   1 wxWidgets for MGL installation
   2 ------------------------------
   3
   4 IMPORTANT NOTE:
   5
   6   wxMGL is currently in need of some work to bring it up to the
   7   standard of some of the other wxWidgets ports.
   8
   9   If you experience problems installing, please re-read these
  10   instructions and other related files (todo.txt, bugs.txt and
  11   osname.txt for your platform if it exists) carefully before
  12   mailing wxwin-users or the author. Preferably, try to fix the
  13   problem first and then send a patch to the author.
  14
  15   When sending bug reports tell us what version of wxWidgets you are
  16   using (including the beta) and what compiler on what system. One
  17   example: wxMGL 2.8.0, gcc 2.95.3, Redhat 7.0
  18
  19 First steps
  20 -----------
  21
  22 - Download SciTech MGL library from http://www.scitechsoft.com. The
  23   downloads page is here (you need MGL version 5.0beta7 or newer):
  24   http://scitechsoft.com/products/dev/mgl_download/mgl_down.html
  25
  26   Install MGL according to provided instructions. In particular, make sure that
  27   MGL_ROOT and NUCLEUS_PATH environment variables are set before attempting to
  28   build wxMGL.
  29
  30   Make sure you installed all MGL components, including the "fonts" package
  31   (it's called mgl_<ver>-font.tar.gz in Linux version). It is important to have
  32   SciTech's basic fonts in $(MGL_ROOT)/fonts directory (you may want to add
  33   Arial TrueType font for better output quality) and basic cursors in
  34   $(MGL_ROOT)/cursors. wxMGL depends on their presence.
  35
  36 - Download wxMGL-x.y.z.tgz, where x.y.z is the version number.
  37   Download documentation in a preferred format, such as
  38   wxWidgets-HTML.zip or wxWidgets-PDF.zip.
  39
  40 - Make a directory such as ~/wx and unarchive the files into this
  41   directory.
  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 below 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:
 115     http://www.delorie.com/djgpp/getting.html
 116
 117 Scitech MGL must be compiled natively, and to do this you will need to download
 118 the following files (from the current/v2 and current/v2gnu directories). You
 119 should get the latest versions available rather than the exact versions shown
 120 below, they are just an example of what to look for:
 121
 122 djdev203.zip B   1,530,778 020811 DJGPP development kit 2.03
 123 bnu2161b.zip B   3,483,132 050708 GNU Binutils 2.16.1 for DJGPP V2
 124 gcc344b.zip  B   3,772,211 050527 GNU GCC 3.4.4 for DJGPP V2
 125 gpp344b.zip  B   4,026,725 050527 GNU C++ Compiler 3.4.4 for DJGPP V2
 126
 127 If you want to build wxMGL natively using the DJGPP compiler, you will have to
 128 install a couple of Unix utilities. I think the following is the minimum that
 129 will work:
 130
 131 bsh204b.zip  B     454,308 020106 GNU Bash shell 2.04 for DJGPP V2
 132 fil41b.zip   B   1,738,170 030830 GNU fileutils 4.1 for DJGPP V2
 133 find41b.zip  B     306,826 010505 GNU findutils 4.1 for DJGPP V2
 134 grep24b.zip  B     254,997 000116 GNU Grep 2.4 for DJGPP V2
 135 mak3791b.zip B     272,798 020106 GNU Make 3.79.1 for DJGPP V2
 136 sed414b.zip  B     159,920 050331 GNU Sed 4.1.4 for DJGPP V2
 137 shl2011b.zip B   1,195,021 020419 GNU sh-utils 2.01 for DJGPP V2
 138
 139 You'll probably also want a debugger:
 140 gdb611b.zip  B   1,585,648 040629 GNU GDB Debugger 6.1.1 for DJGPP V2
 141
 142 And maybe some of these:
 143 faq230b.zip  B     679,865 000203 FAQ 2.30 for DJGPP v2.03
 144 dif281b.zip  B     402,859 040911 GNU Diffutils 2.8.1 for DJGPP V2
 145 gwk314b.zip  B     968,667 050321 GNU Awk 3.1.4 for DJGPP V2
 146 gzip135b.zip B     146,138 041215 GNU gzip 1.3.5 for DJGPP V2
 147 lss374b.zip  B     199,805 020405 GNU Less 374 for DJGPP V2
 148 pat254b.zip  B     114,250 040326 GNU Patch 2.5.4 for DJGPP V2
 149 tar112ab.zip B     236,427 000305 GNU Tar 1.12a for DJGPP V2
 150 whic211b.zip B      86,296 000911 GNU which 2.11 for DJGPP V2
 151
 152 The system you compile on must support long file names. You can use Windows 9x
 153 or an x86 version of Windows 2000/XP or later. For example:
 154
 155 C:\>set MGL_ROOT=c:/scitech
 156 C:\>set DJGPP=c:/djgpp/djgpp.env
 157 C:\>PATH=c:\djgpp\bin
 158 C:\>set PS1=\w\$
 159 C:\>bash
 160 c:/$ mkdir build
 161 c:/$ cd build
 162 c:/build$ ../wxWidgets/configure
 163 c:/build$ make
 164 c:/build$ cd samples/minimal
 165 c:/build/samples/minimal$ make
 166
 167 Cross-compilation is very easy. It works like ordinary compilation with
 168 configure, you only have to specify the target:
 169
 170 > ./configure --with-mgl --build=i586-linux --host=i586-pc-msdosdjgpp
 171 > make
 172
 173 For this to work, you must have installed a cross compiler on your system.
 174
 175 Linux rpms are available here:
 176     http://ap1.pp.fi/djgpp/gcc/cross-compiler/index.html
 177
 178 NetBSD has a binary package which can be installed with:
 179     # pkg_add cross-i386-msdosdjgpp
 180
 181 For other systems you will need to obtain the djgpp sources and compile them
 182 yourself.
 183
 184
 185 * Building wxMGL for MS-DOS using Watcom C/C++
 186 -----------------------------------------------
 187
 188 <Note: this section is currently out of date>
 189
 190 You will need Watcom C/C++ compiler version 11 or newer (Watcom is going to be
 191 OpenSourced by SciTech, check out http://www.openwatcom.org).
 192
 193 1. Edit $(WXDIR)\include\wx\univ\setup.h to suit your needs (in same way as you
 194    do when compiling wxMSW).
 195
 196 2. Go to $(WXDIR)\src\mgl and run
 197    > wmake -f makefile.wat all
 198
 199 3. You can compile the samples by typing 'wmake -f makefile.mgl all' in sample
 200    directory if this file is available. If it is not, copy makefile.wat to
 201    makefile.mgl and replace the line that says
 202
 203        !include $(WXDIR)\src\makeprog.wat
 204
 205    with
 206
 207        !include $(WXDIR)\src\mgl\makeprog.wat
 208
 209
 210 Compilation notes for MGL with gcc
 211 ----------------------------------
 212
 213 The mvis library doesn't compile with current versions of gcc. However wxMGL
 214 does not use this part of MGL, so it can be taken out of the compile, e.g.:
