   1 wxWidgets 2.5 for MGL installation
   2 ------------------------------------
   3
   4 IMPORTANT NOTE:
   5
   6   If you experience problems installing, please re-read these
   7   instructions and other related files (todo.txt, bugs.txt and
   8   osname.txt for your platform if it exists) carefully before
   9   mailing wxwin-users or the author. Preferably, try to fix the
  10   problem first and then send a patch to the author.
  11
  12   When sending bug reports tell us what version of wxWidgets you are
  13   using (including the beta) and what compiler on what system. One
  14   example: wxMGL 2.5.1, gcc 2.95.3, Redhat 7.0
  15
  16 First steps
  17 -----------
  18
  19 - Download SciTech MGL library (version 5.0) from http://www.scitechsoft.com.
  20   The downloads page is here (you need MGL version 5.0beta7 or newer):
  21   http://www.scitechsoft.com/products/embedded/mgl_home.html
  22
  23   Install MGL according to provided instructions. In particular, make sure that
  24   MGL_ROOT and NUCLEUS_PATH environment variables are set before attempting to
  25   build wxMGL.
  26
  27   Make sure you installed all MGL components, including the "fonts" package
  28   (it's called mgl50b7-font.tar.gz in Linux version). It is important to have
  29   SciTech's basic fonts in $(MGL_ROOT)/fonts directory (you may want to add
  30   Arial TrueType font for better output quality) and basic cursors in
  31   $(MGL_ROOT)/cursors. wxMGL depends on their presence.
  32
  33 - Download wxMGL-x.y.z.tgz, where x.y.z is the version number.
  34   Download documentation in a preferred format, such as
  35   wxWidgets-HTML.zip or wxWidgets-PDF.zip.
  36
  37 - Make a directory such as ~/wx and unarchive the files into this
  38   directory.
  39
  40 - It is recommended that you install bison and flex; using yacc
  41   and lex may require tweaking of the makefiles.
  42
  43 - You can now use configure or makefiles to build wxWidgets and the samples.
  44   In case of problems, please use GNU make.
  45
  46
  47 COMPILING
  48 =========
  49
  50 Following systems are supported by wxMGL so far:
  51  - Unix (Linux etc.)
  52  - MS-DOS (DJGPP and Watcom compilers)
  53
  54
  55 * Compiling using configure
  56 ----------------------------
  57
  58 These instructions apply to installation on a Unix system (such as Linux). Please
  59 see bellow for information on using configure on non-Unix platforms.
  60
  61 If you compile wxWidgets on Linux for the first time and don't like to read
  62 install instructions just do (in the base dir):
  63
  64 > ./configure --with-mgl
  65 > make
  66 > su <type root password>
  67 > make install
  68 > ldconfig
  69 > exit
  70
  71 Afterwards you can continue with
  72
  73 > make
  74 > su <type root password>
  75 > make install
  76 > ldconfig
  77 > exit
  78
  79 If you want to remove wxWidgets on Unix you can do this:
  80
  81 > su <type root password>
  82 > make uninstall
  83 > ldconfig
  84 > exit
  85
  86 You can set many options to configure. Type
  87
  88 > ./configure --help
  89
  90 and you will get a list of supported options.
  91
  92
  93 * Using wxMGL library built with configure
  94 -------------------------------------------
  95
  96 'make install' will install wx-config script that can (and should) be used
  97 to get compiler flags that are needed to build your program. wx-config --cxxflags
  98 will output necessary C++ compiler flags and wx-config --libs will list all
  99 needed libraries. See an example of wxWidgets application makefile:
 100
 101 minimal: minimal.o
 102         $(CC) -o minimal minimal.o `wx-config --libs`
 103
 104 minimal.o: minimal.cpp mondrian.xpm
 105         $(CC) `wx-config --cxxflags` -c minimal.cpp -o minimal.o
 106
 107
 108 * Using configure to build MS-DOS version
 109 ------------------------------------------
 110
 111 Even though configure is a Unix script, you can use it to build MS-DOS version
 112 of the wxMGL library. There are two possible ways to achieve this: you can
 113 either cross-compile from Unix or compile natively. Either way you will needed
 114 the DJGPP port of GCC compiler freely available from http://www.djgpp.org. You will
 115 also need DJGPP version of SciTech MGL (this must be built using native tools).
 116
 117 Cross-compilation is very easy. It works like ordinary compilation with configure,
 118 you only have to specify the target:
 119
 120 > ./configure --with-mgl --build=i586-linux --host=i586-pc-msdosdjgpp
 121 > make
 122
 123 If you want to build wxMGL natively using DJGPP compiler, you will have to install
 124 a couple of Unix utilities. The easiest way to get them is to install the Cygwin
 125 package (available from RedHat, see http://freshmeat.net/search/?q=cygwin for exact
 126 URL). Cygwin contains win32 compiler, so make sure you did *not* install it! Once
 127 you have Cygwin utilities and DJGPP compiler in your PATH, run bash.exe and type
 128
 129 > ./configure --with-mgl
 130 > make
 131
 132 in wxWidgets top directory. You can build wxMGL in MS-DOS with configure, sorry.
 133
 134
 135 * Building wxMGL for MS-DOS using Watcom C/C++
 136 -----------------------------------------------
 137
 138 You will need Watcom C/C++ compiler version 11 or newer (Watcom is going to be
 139 OpenSourced by SciTech, check out http://www.openwatcom.org).
 140
 141 1. Edit $(WXDIR)\include\wx\univ\setup.h to suit your needs (in same way as you
 142    do when compiling wxMSW).
 143
 144 2. Go to $(WXDIR)\src\mgl and run
 145    > wmake -f makefile.wat all
 146
 147 3. You can compile the samples by typing 'wmake -f makefile.mgl all' in sample
 148    directory if this file is available. If it is not, copy makefile.wat to
 149    makefile.mgl and replace the line that says
 150
 151        !include $(WXDIR)\src\makeprog.wat
 152
 153    with
 154
 155        !include $(WXDIR)\src\mgl\makeprog.wat
 156
