-wxWindows 2.0 for Motif installation
-------------------------------------
-
-IMPORTANT NOTE: If you experience problems installing, please
-re-read this instructions and other related files (todo.txt,
-bugs.txt etc.) carefully before mailing wxwin-users or
-the author. Preferably, try to fix the problem first and
-then send a patch to the author.
-
-- Prerequisites: Motif 1.2 or above, or Lesstif
- (not yet tested). Motif 2.0 and above may also be suitable.
+wxWidgets for Motif installation
+--------------------------------
+
+IMPORTANT NOTE:
+
+ If you experience problems installing, please re-read these
+ instructions and other related files (todo.txt, bugs.txt and
+ osname.txt for your platform if it exists) carefully before
+ mailing wx-users or the author. Preferably, try to fix the
+ problem first and then send a patch to the author.
+
+ When sending bug reports tell us what version of wxWidgets you are
+ using (including the beta) and what compiler on what system. One
+ example: wxMotif 2.8.1, gcc 2.95.4, Redhat 6.1
+
+First steps
+-----------
-- Download the files wx200gen.zip and wx200mot.zip, and
- documentation in a preferred format, such as wx200htm.zip
- or wx200pdf.zip.
+- Prerequisites: Motif 1.2 or above, or Lesstif. Motif 2.0 and
+ above may also be suitable.
-- Make a directory such as ~/wx and unzip the files into this
- directory. Use the -a option if available to convert the ASCII
- files to Unix format. Don't worry about files being
- overwritten: they should be identical anyway.
+- Download wxX11-x.y.z.tgz, where x.y.z is the version number.
+ (wxMotif is included in the wxX11 distribution).
+ Download documentation in a preferred format, such as
+ wxWidgets-HTML.zip or wxWidgets-PDF.zip.
- (See http://www.cdrom.com/pub/infozip/ if you don't have zip/unzip
- already installed. Zip isn't the same as gzip!)
+- Make a directory such as ~/wx and unarchive the files into this
+ directory.
- It is recommended that you install bison and flex; using yacc
and lex may require tweaking of the makefiles. You also need
- Xpm (see comments in the Notes section below).
+ libXpm (see comments in the Notes section below) if you want to have
+ XPM support in wxWidgets (recommended).
+
+- You can now use configure to build wxWidgets and the samples.
+
+ Using configure is the only way to build the library. If it doesn't
+ work for you for whatever reason, please report it (together with detailed
+ information about your platform and the (relevant part of) contents of
+ config.log file) to wx-dev@lists.wxwidgets.org.
-- You now have the option of using the configure-based system,
- or the simple makefile system. Configure is more hard to debug
- if things go wrong, but may be easier to use if they go OK :-)
- Makefiles are easier to tweak.
COMPILING USING CONFIGURE
=========================
-- You can use the wxGTK configure system to make wxMotif, or
- you can follow the following steps to use the simpler (but
- less automatic) makefile system. If using configure, the
- following script should make the library and samples, when
- run from the top-level wxWindows directory (see also 'makewxmotif'
- in this directory). Make this script executable with the command
- chmod a+x makewxmotif.
+* The simplest case
+-------------------
- -------:x-----Cut here-----:x-----
- # makewxmotif
- # Sets permissions (in case we extracted wxMotif from zip files)
- # and makes wxMotif.
- # Call from top-level wxWindows directory.
- # Note that this uses standard (but commonly-used) configure options;
- # if you're feeling brave, you may wish to compile with threads.
- # -- Julian Smart
- chmod a+x configure config.sub config.guess setup/general/* setup/shared/*
- ./configure --with-shared --with-motif --without-gtk --with-debug_flag --with-debug_info --without-threads
- make makefiles
- make
- -------:x-----Cut here-----:x-----
+If you compile wxWidgets on Linux for the first time and don't like to read
+install instructions just do (in the base dir):
- This script will build wxMotif using shared libraries.
+> ./configure --with-motif
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
-- Change directory to a sample e.g. samples/minimal, and type make.
- The binary will end up under the Linux (or other appropriate) subdirectory.
+Afterwards you can continue with
-- To build an application outside the wxWindows hierarchy, you can
- use `wx-config --cflags` when compiling source files and `wx-config --libs`
- when linking, where wx-config is in the wxWindows root directory.
- These invocations return the appropriate flags for the compiler.
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
-- When compiling certain utilities such as Dialog Editor, you may find
- that the makefile refers to wx-config as above. Unless you have used
- "make install" to install wxWindows, wx-config won't be found, so
- either edit the makefile to hard-wire the flags, or place wx-config
- where it will be found by the makefile.
+If you want to remove wxWidgets on Unix you can do this:
-COMPILING USING MAKEFILES
-=========================
+> su <type root password>
+> make uninstall
+> ldconfig
+> exit
-- Choose a .env file from src/makeenvs that matches your
- environment, and copy it to src/make.env. These are the
- settings read by wxWindows for Motif makefiles.
+* The expert case
+-----------------
-- Edit src/make.env to change options according to your local
- environment. In particular, change WXDIR to where wxWindows is
- found on your system, or set the WXWIN environment variable
- before compilation, e.g.:
+If you want to do some more serious cross-platform programming with wxWidgets,
+such as for GTK and Motif, you can now build two complete libraries and use
+them concurrently. For this end, you have to create a directory for each build
+of wxWidgets - you may also want to create different versions of wxWidgets
+and test them concurrently. Most typically, this would be a version configured
+with --enable-debug and one without.
- export WXWIN=/home/jacs/wx2
+For building three versions (one GTK, one Motif and a debug version of the GTK
+source) you'd do this:
- Please feel free to contribute settings files for your environment.
+mkdir buildmotif
+cd buildmotif
+../configure --with-motif
+make
+cd ..
-- Change directory to src/motif and type:
+mkdir buildgtk
+cd buildgtk
+../configure --with-gtk
+make
+cd ..
- make -f makefile.unx motif
+mkdir buildgtkd
+cd buildgtkd
+../configure --with-gtk --enable-debug
+make
+cd ..
- This should make the library libwx_motif.a in the lib
- directory. Note that this makefile system does not build shared
- libraries, only static ones (that is, the wxWindows library will be
- linked statically; to see remaining dependencies on shared libraries,
- type e.g. ldd minimal_motif).
+Note that since wxWidgets-2.6.0 you can install all those libraries
+concurrently, you just need to pass the appropriate flags when using them.
-- Make a sample, such as the minimal sample:
+* The simplest errors
+---------------------
- cd samples/minimal
- make -f makefile.unx motif
+You get errors during compilation: The reason is that you probably have a
+broken compiler. GCC 2.8 and earlier versions and egcs are likely to cause
+problems due to incomplete support for C++ and optimisation bugs. Best to use
+GCC 2.95 or later.
- and run the resulting minimal_motif binary.
+You get immediate segfault when starting any sample or application: This is
+either due to having compiled the library with different flags or options than
+your program - typically you might have the __WXDEBUG__ option set for the
+library but not for your program - or due to using a compiler with optimisation
+bugs.
-Troubleshooting
+* The simplest program
+----------------------
+
+Now create your super-application myfoo.app and compile anywhere with
+
+g++ myfoo.cpp `wx-config --libs --cxxflags` -o myfoo
+
+* General
+---------
+
+The Unix variants of wxWidgets use GNU configure. If you have problems with
+your make use GNU make instead.
+
+If you have general problems with installation, see the wxWidgets website at
+
+ http://www.wxwidgets.org/
+
+for newest information. If you still don't have any success, please send a bug
+report to one of our mailing lists (see my homepage) INCLUDING A DESCRIPTION OF
+YOUR SYSTEM AND YOUR PROBLEM, SUCH AS YOUR VERSION OF MOTIF, WXMOTIF, WHAT
+DISTRIBUTION YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect,
+but I tried...
+
+* GUI libraries
---------------
-- If you have trouble compiling the file y_tab.c, or have strange
- linking errors, check whether you're using a C or C++ compiler for this file.
- You should specify a C compiler in the CCLEX variable in src/make.env.
- You could also try using bison and flex instead of yacc and
- lex.
+wxWidgets/Motif requires the Motif library to be installed on your system. As
+an alternative, you may also use the free library "lesstif" which implements
+most of the Motif API without the licence restrictions of Motif.
+
+You can get the newest version of the Lesstif from the lesstif homepage at:
+
+ http://www.lesstif.org/
+
+* Additional libraries
+----------------------
+
+wxWidgets/Motif requires a thread library and X libraries known to work with
+threads. This is the case on all commercial Unix-Variants and all
+Linux-Versions that are based on glibc 2 except RedHat 5.0 which is broken in
+many aspects. As of writing this, virtually all Linux distributions have
+correct glibc 2 support.
+
+You can disable thread support by running
+
+./configure --disable-threads
+make
+su <type root password>
+make install
+ldconfig
+exit
+
+* Building wxMotif on OS/2
+--------------------------
+
+Please send comments and question about the OS/2 installation
+to Stefan Neis <Stefan.Neis@t-online.de> and patches to
+the wxWidgets mailing list.
+
+In the following list, the version numbers indicate the configuration that
+was actually used by myself, newer version should cause no problems and
+even older ones are expected to work most of the time.
+
+You'll need OS/2 Warp (4.51) or eCS(1.0), X-Free86/2 (3.3.6 or newer),
+Lesstif (0.92.7 or newer), emx (0.9d fix 4), a Unix like shell (pdksh-5.2.14
+or ash), Autoconf (2.57), GNU file utilities (3.13), GNU text utilities (1.19),
+GNU shell utilites (1.12), m4 (1.4), sed (2.05), grep (2.0), Awk (3.0.3),
+GNU Make (3.75).
+
+Preferably, you should have Posix/2 installed and C(PLUS)_INCLUDE_PATH and
+LIBRARY_PATH set up accordingly, however, wxGTK will even work without it.
+Presence of Posix/2 will be auto-detected.
+
+Open an OS/2 prompt and switch to the directory above.
+Set MAKESHELL or MAKE_SHELL (which one is needed depends on the version of
+make) to a Unix like shell, e.g.
+SET MAKESHELL=ash
+If you have a really deficient version of GNU make, it might even be
+necessary to set SHELL or even COMSPEC to a unix like shell as well.
+Depending on your installation you might want to also set INSTALL, for me
+it tends to try to use the system's tcpip\pcomos\install.exe which causes
+problems, e.g.
+SET INSTALL=<path_to_src_directory>/install-sh -c
-- Solaris compilation with gcc: if the compiler has problems with the variable argument
- functions, try putting the gcc fixinclude file paths early in the
- include path.
+Notice that the delivered configure scripts are fully OS/2 aware, so you
+can simply run
+ ash -c "configure --with-motif"
+and make and possibly make install as described above.
+
+To verify Lesstif installation, configure will try to compile a
+sample program that requires X headers/libraries to be either
+available via C_INCLUDE_PATH and LIBRARY_PATH or you need to
+explicitly set CFLAGS prior to running configure.
+
+* Building wxMotif on SGI
+-------------------------
+
+Using the SGI native compilers, it is recommended that you
+also set CFLAGS and CXXFLAGS before running configure. These
+should be set to :
+
+CFLAGS="-mips3 -n32"
+CXXFLAGS="-mips3 -n32"
+
+This is essential if you want to use the resultant binaries
+on any other machine than the one it was compiled on. If you
+have a 64bit machine (Octane) you should also do this to ensure
+you don't accidently build the libraries as 64bit (which is
+untested).
+
+The SGI native compiler support has only been tested on Irix 6.5.
+
+* Building wxMotif on Cygwin
+----------------------------
+
+The normal build instructions should work fine on Cygwin. The one difference
+with Cygwin is that when using the "--enable-shared" configure option (which
+is the default) the API is exported explicitly using __declspec(dllexport)
+rather than all global symbols being available.
+
+This shouldn't make a difference using the library and should be a little
+more efficient. However if an export attribute has been missed somewhere you
+will see linking errors. If this happens then you can work around the
+problem by setting LDFLAGS=-Wl,--export-all-symbols. Please also let us know
+about it on the wx-dev mailing list.
+
+* Create your configuration
+---------------------------
+
+Usage:
+ ./configure [options]
+
+If you want to use system's C and C++ compiler,
+set environment variables CXX and CC as
+
+ % setenv CC cc
+ % setenv CXX CC
+ % ./configure options
+
+to see all the options please use:
+
+ ./configure --help
+
+The basic philosophy is that if you want to use different
+configurations, like a debug and a release version,
+or use the same source tree on different systems,
+you have only to change the environment variable OSTYPE.
+(Sadly this variable is not set by default on some systems
+in some shells - on SGI's for example). So you will have to
+set it there. This variable HAS to be set before starting
+configure, so that it knows which system it tries to
+configure for.
+
+Configure will complain if the system variable OSTYPE has
+not been defined. And Make in some circumstances as well...
+
+
+* General options
+-------------------
+
+Given below are the commands to change the default behaviour,
+i.e. if it says "--disable-threads" it means that threads
+are enabled by default.
-Other Notes
+Many of the configure options have been thoroughly tested
+in wxWidgets snapshot 6, but not yet all (ODBC not).
+
+You have to add --with-motif on platforms, where Motif is
+not the default (on Linux, configure will default to GTK).
+
+ --with-motif Use either Motif or Lesstif
+ Configure will look for both.
+
+The following options handle the kind of library you want to build.
+
+ --disable-threads Compile without thread support. Threads
+ support is also required for the
+ socket code to work.
+
+ --disable-shared Do not create shared libraries.
+
+ --enable-monolithic Build wxWidgets as single library instead
+ of as several smaller libraries (which is
+ the default since wxWidgets 2.5.0).
+
+ --disable-optimise Do not optimise the code. Can
+ sometimes be useful for debugging
+ and is required on some architectures
+ such as Sun with gcc 2.8.X which
+ would otherwise produce segvs.
+
+ --enable-profile Add profiling info to the object
+ files. Currently broken, I think.
+
+ --enable-no_rtti Enable compilation without creation of
+ C++ RTTI information in object files.
+ This will speed-up compilation and reduce
+ binary size.
+
+ --enable-no_exceptions Enable compilation without creation of
+ C++ exception information in object files.
+ This will speed-up compilation and reduce
+ binary size. Also fewer crashes during the
+ actual compilation...
+
+ --enable-no_deps Enable compilation without creation of
+ dependency information.
+
+ --enable-permissive Enable compilation without checking for strict
+ ANSI conformance. Useful to prevent the build
+ dying with errors as soon as you compile with
+ Solaris' ANSI-defying headers.
+
+ --enable-mem_tracing Add built-in memory tracing.
+
+ --enable-dmalloc Use the dmalloc memory debugger.
+ Read more at www.letters.com/dmalloc/
+
+ --enable-debug Equivalent to --enable-debug_info plus
+ --enable-debug-flag.
+
+ --enable-debug_info Add debug info to object files and
+ executables for use with debuggers
+ such as gdb (or its many frontends).
+
+ --enable-debug_flag Define __DEBUG__ and __WXDEBUG__ when
+ compiling. This enable wxWidgets' very
+ useful internal debugging tricks (such
+ as automatically reporting illegal calls)
+ to work. Note that program and library
+ must be compiled with the same debug
+ options.
+
+* Feature Options
+-----------------
+
+Many of the configure options have been thoroughly tested
+in wxWidgets snapshot 6, but not yet all (ODBC not).
+
+When producing an executable that is linked statically with wxGTK
+you'll be surprised at its immense size. This can sometimes be
+drastically reduced by removing features from wxWidgets that
+are not used in your program. The most relevant such features
+are
+
+ --without-libpng Disables PNG image format code.
+
+ --without-libjpeg Disables JPEG image format code.
+
+ --without-odbc Disables ODBC code.
+
+ --without-libtiff Disables TIFF image format code.
+
+ --without-expat Disable XML classes based on Expat parser.
+
+ --disable-threads Disables threads. Will also
+ disable sockets.
+
+ --disable-sockets Disables sockets.
+
+ --disable-dnd Disables Drag'n'Drop.
+
+ --disable-clipboard Disables Clipboard.
+
+ --disable-streams Disables the wxStream classes.
+
+ --disable-file Disables the wxFile class.
+
+ --disable-textfile Disables the wxTextFile class.
+
+ --disable-intl Disables the internationalisation.
+
+ --disable-validators Disables validators.
+
+ --disable-accel Disables accel.
+
+Apart from disabling certain features you can very often "strip"
+the program of its debugging information resulting in a significant
+reduction in size.
+
+Please see the output of "./configure --help" for comprehensive list
+of all configurable options.
+
+
+* Compiling
-----------
-- Better installation and makefile systems are
- required. A revised configure system is in preparation.
+The following must be done in the base directory (e.g. ~/wxMotif
+or ~/wxWin or whatever)
+
+Now the makefiles are created (by configure) and you can compile
+the library by typing:
+
+ make
+
+make yourself some coffee, as it will take some time. On an old
+Pentium 200 around 40 minutes. During compilation, you may get a few
+warning messages depending in your compiler.
+
+If you want to be more selective, you can change into a specific
+directory and type "make" there.
+
+Then you may install the library and its header files under
+/usr/local/include/wx and /usr/local/lib respectively. You
+have to log in as root (i.e. run "su" and enter the root
+password) and type
+
+ make install
+
+You can remove any traces of wxWidgets by typing
+
+ make uninstall
+
+If you want to save disk space by removing unnecessary
+object-files:
+
+ make clean
+
+in the various directories will do the work for you.
+
+* Creating a new Project
+------------------------
+
+1) The first way uses the installed libraries and header files
+automatically using wx-config
+
+g++ myfoo.cpp `wx-config --libs` `wx-config --cxxflags` -o myfoo
+
+Using this way, a make file for the minimal sample would look
+like this
+
+CXX = g++
-- Debugging mode is switched on by default. To compile in non-debug
- mode, remove the -D__WXDEBUG__ switch in make.env (or if using the
- configure system, change --with-debug_flag to --without_debug_flag
- and --with-debug_info to --without-debug_info in the makewxmotif
- script).
+minimal: minimal.o
+ $(CXX) -o minimal minimal.o `wx-config --libs`
-- Some classes can be switched off in include/wx/motif/setup.h,
- if you are having trouble with a particular file. However,
- I'd prefer you to fix the problem and send the fix to me :-) or at
- least let me know about it.
+minimal.o: minimal.cpp
+ $(CXX) `wx-config --cxxflags` -c minimal.cpp -o minimal.o
-- Thread support is switched off by default in setup.h (wxUSE_THREADS)
- because standard Unices often do not have the necessary thread library
- installed. Please see ../docs/gtk/install.txt for more details on this.
- For Linux, the problem is expected to go away with future
- distributions of the operating system.
+clean:
+ rm -f *.o minimal
-- If you run into problems with a missing X11/Xpm.h header, you
- need to install the XPM package. It can be obtained from:
+If your application uses only some of wxWidgets libraries, you can
+specify required libraries when running wx-config. For example,
+`wx-config --libs=html,core` will only output link command to link
+with libraries required by core GUI classes and wxHTML classes. See
+the manual for more information on the libraries.
- ftp://ftp.x.org/contrib/libraries/xpm-3.4k.tar.gz
- http://sunfreeware.com
+2) The other way creates a project within the source code
+directories of wxWidgets. For this endeavour, you'll need
+GNU autoconf version 2.14 and add an entry to your Makefile.in
+to the bottom of the configure.in script and run autoconf
+and configure before you can type make.
- You may need to modify make.env to add -I and -L options pointing to where Xpm
- is installed and possibly change bitmap.cpp to
- include <xpm.h> instead of <X11/xpm.h>
+* Further notes by Julian Smart
+---------------------------------
+
+- You may find the following script useful for compiling wxMotif,
+ especially if installing from zips (which don't preserve file
+ permissions). Make this script executable with the command
+ chmod a+x makewxmotif.
+
+ -------:x-----Cut here-----:x-----
+ # makewxmotif
+ # Sets permissions (in case we extracted wxMotif from zip files)
+ # and makes wxMotif.
+ # Call from top-level wxWidgets directory.
+ # Note that this uses standard (but commonly-used) configure options;
+ # if you're feeling brave, you may wish to compile with threads:
+ # if they're not supported by the target platform, they will be disabled
+ # anyhow
+ # -- Julian Smart
+ chmod a+x configure config.sub config.guess
+ ./configure --with-shared --with-motif --with-debug_flag --with-debug_info --enable-debug --without-threads --without-sockets --without-odbc
+ make
+ -------:x-----Cut here-----:x-----
+
+ This script will build wxMotif using shared libraries. If you want to build
+ a static wxWidgets library, use --disable-shared.
+
+Troubleshooting
+---------------
+
+- Solaris compilation with gcc: if the compiler has problems with the variable
+ argument functions, try putting the gcc fixinclude file paths early in the
+ include path.
+
+- If you operator-related compile errors or strange memory problems
+ (for example in deletion of string arrays), set wxUSE_GLOBAL_MEMORY_OPERATORS
+ and wxUSE_MEMORY_TRACING to 0 in setup.h, and recompile.
+
+- If you get an internal compiler error in gcc, turn off optimisations.
+
+- Problems with XtDestroyWidget crashing in ~wxWindow have been
+ reported on SGI IRIX 6.4. This has not yet been resolved, so
+ any advice here would be very welcome. See bugs.txt for a
+ possible temporary workaround (comment out the final
+ XtDestroyWidget from ~wxWindow in window.cpp).
+
+- Some compilers, such as Sun C++, may give a lot of warnings about
+ virtual functions being hidden. Please ignore these, it's correct C++ syntax.
+ If you find any incorrect instances, though, such as a
+ missing 'const' in an overridden function, please let us know.
+
+Other Notes
+-----------
- Alternatively, edit include/motif/setup.h, set wxUSE_XPM
- to 0, and recompile. You will not be able to load any XPMs,
- though (currently the only supported colour bitmap format).
+- Using configure will create a release build of the library by
+ default: it's recommended to use --enable-debug configure switch
+ while developing your application. To compile in non-debug mode, use
+ --disable-debug configure switch.
