* General
----------
wxGTK uses GNU configure. If you have problems with your make use GNU
make instead.
* Create your configuration
-----------------------------
Usage:
./configure options
If you want to use system's C and C++ compiler,
set environment variables CC and CCC as
% setenv CC cc
% setenv CCC 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
-------------------
The following options handle the kind of library you want to build.
--with-shared Create shared libraries.
--without-optimise Do not optimise the code.
--with-profile Add profiling info to the
object files. Currently
broken.
--with-mem_tracing Add built-in memory tracing.
Not yet.
--with-debug Add debug info to object
files.
* Feature Options
-------------------
When using the Windows version of wxWindows, it is possible
to edit the file /include/wx/msw/setup.h in order to enable
or disable some features of wxWindows so that the resulting
binaries get smaller.
As I don't yet care for binary size and target mainly at
producing a shared library, wxGTK's configure system auto-
matically enables all features, as long as they are already
implemented.
* Additional libraries
-----------------------
[Note: Currently wxGTK will compile out-of-the-box
with no extra libraries required. Support for
OpenGl, threads, Python and hopefully ODBC
support will soon be added.]
wxGTK requires the GTK (The Gimp Toolkit) to be installed,
which probably makes sense.
There will be a few more features of wxGTK, which will
require further libraries (on some platforms). These
features will be optional. I hope to teach configure
to check that out automatically.
Thread support:
Requires pthreads under Linux without glibc or glibc 2.
OpenGl:
Requires OpenGl or MesaGl.
Python scripting language support:
Requires Python.
* Compiling
-------------
First you have to create all makefiles in all subdirectories:
make makefiles
Dependencies are generated automatically using
make depend
Now the makefiles are created you can compile everything is as simple
as typing:
make
make yourself some coffee, as it will try to compile
ALL the files in this distribution.
if you want to be more selective:
make src will build only the base libraries
make utils will build the utils
make samples will build the samples
make other will build the other samples
make user will build the files in the directory other
Depending on the configuration of some files, the libraries
and binaries will be placed in different directories.
The "global" binaries and libraries will be placed in:
bin/$(OSTYPE) and
lib/$(OSTYPE) respectively
"local" binaries and libraries will be placed in:
(basedir of that application)/$(OSTYPE).
This is also the place where all the object-files will go.
If you want to conserve disk space by removing unnecessary
object-files:
make clean_obj
will do the work for you.
* Creating a new Project
--------------------------
I propose to put all contributed programs in the directory
"user", with a directory of its own.
This directory then should include the following files:
Makefile (You can copy this one from any application in samples
probably you will not need to edit this one. There is
only one case where you might be interested in changing
this file, but about that see later.)
Makefile.in (This is the base application-Makefile template, from
which the actual Makefile for each system is created.
More about this later)
put ALL your source code along with all the other stuff you need for
your application in this directory (subdirectories are welcome).
** Something about Makefiles
------------------------------
On general principle it should only contain ONE line, which is as follows:
include ../../src/gtk/setup/general/makeapp
this will include all the necessary definitions for creating the applications
the only case where you might want to add another line is the following:
this version of configure also supports creation of source archives of the
application for easy distribution and updates to newer version of wxxt.
For this purpose all files in the application-directory will be put into
a gziped tar-file in the full notation user/<your application>/*
if you want to include some other files that you want "more visible", like
a README.<yourApp> or a shell script for easy
compilation/installation/distribution, then you have to add a variable
DISTRIBUTE_ADDITIONAL=<your files>
to the Makefile.
So it would look like this:
DISTRIBUTE_ADDITIONAL=README.TheApp
include ../../src/gtk/setup/general/makeapp
As we have already talked about distribution the command to create a
distribution is:
make distrib
NOTE: If you are in the base directory of wxxt it will create
distribution packages for wxxt as well as for all packages in the
user directory.
So if you want to create only packages for the files in user,
then go to the directory other and type:
make distrib
or if you only want one application to be created then
enter the specific directory and type there:
make distrib
All the distribution files will be put in the directory
distrib at the base of the wxxt-tree (where also configure
and template.mak can be found).
** Something about Makefile.in
--------------------------------
As you have already seen with Makefile, configure makes a lot of use
if the include statement in make to keep the Makefiles as simple as
possible.
So basically there are only variables to define and then a include command.
Exception to this rule is if you have special rules for some stuff...
These rules should go AFTER the include statement!!!
so the general header looks like this:
# wxGTK base directory
WXBASEDIR=@WXBASEDIR@
# set the OS type for compilation
OS=@OS@
# compile a library only
RULE=bin
and the general footer will look like this:
# include the definitions now
include ../../../template.mak
the key variable is RULE, which defines what make should create
in this directory.
here are some examples:
RULE description
===========================================================================
bin creates a local binary (for a global binary prefix bin with g)
additional variables needed:
BIN_TARGET this gives the name of your application
BIN_OBJ this gives the object files needed to
link the application
optional variables are:
BIN_SRC this gives the list of c/c++ files for
which dependencies will be checked.
(This can be achieved with: make depend)
BIN_LINK this gives commands for additional
libraries needed to link the application
---------------------------------------------------------------------------
bin2 creates two local binaries (for global binaries prefix bin2 with g)
in addition to the variables specified above you MUST also
provide the same variables with BIN2_ instead of BIN_
---------------------------------------------------------------------------
lib creates a local library (for a global binary prefix bin with g)
additional variables needed:
LIB_TARGET this gives the name of your library
LIB_OBJ this gives the object files needed for
the library to be build.
optional variables are:
LIB_SRC this gives the list of c/c++ files for
which dependencies will be checked.
libbin and libgbin are also possible and will need in addition
the variables from bin
---------------------------------------------------------------------------
gslib is similar to lib, but it creates a shared library if the system
supports it.
additional variables needed:
LIB_MAJOR major number of the shared library
LIB_MINOR minor number of the shared library
---------------------------------------------------------------------------
other additional variables:
ADD_COMPILE define additional includes/defines that
are needed to compile the object files
(if you need to reference some directory
utils - like wxGrid -, then please
reference them with the variables defined
in template.mak - e.g.: $(SRCDIR),$(UTILS),
$(SAMPLES),$(OTHERS))
NEEDED_DEFINES lists all the defines that HAVE to be set in
/include/wx/setup.h to compile correctly.
SRC_DIR lists all directories that are needed to
compile. (i.e: lists all the directories,
where there are source-files.) But it is
also needed to clean an object and for
machines, for which make does not support
VPATH
currently there are the following compiling rules provided:
object files are created for the following file extensions:
.c .cc .cpp
Please have a closer look at the Makefiles in this distribution.
* Platforms configure is working with
---------------------------------------
Please report build succes on any machine. Especially non-
Linux operating systems (which I don't have).
