wxWidgets 2.6.3 for MGL installation ------------------------------------ IMPORTANT NOTE: wxMGL is currently in need of some work to bring it up to the standard of some of the other wxWidgets ports. 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 wxwin-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: wxMGL 2.6.2, gcc 2.95.3, Redhat 7.0 First steps ----------- - Download SciTech MGL library from http://www.scitechsoft.com. The downloads page is here (you need MGL version 5.0beta7 or newer): http://scitechsoft.com/products/dev/mgl_download/mgl_down.html Install MGL according to provided instructions. In particular, make sure that MGL_ROOT and NUCLEUS_PATH environment variables are set before attempting to build wxMGL. Make sure you installed all MGL components, including the "fonts" package (it's called mgl_-font.tar.gz in Linux version). It is important to have SciTech's basic fonts in $(MGL_ROOT)/fonts directory (you may want to add Arial TrueType font for better output quality) and basic cursors in $(MGL_ROOT)/cursors. wxMGL depends on their presence. - Download wxMGL-x.y.z.tgz, where x.y.z is the version number. Download documentation in a preferred format, such as wxWidgets-HTML.zip or wxWidgets-PDF.zip. - Make a directory such as ~/wx and unarchive the files into this directory. - You can now use configure or makefiles to build wxWidgets and the samples. In case of problems, please use GNU make. COMPILING ========= Following systems are supported by wxMGL so far: - Unix (Linux etc.) - MS-DOS (DJGPP and Watcom compilers) * Compiling using configure ---------------------------- These instructions apply to installation on a Unix system (such as Linux). Please see below for information on using configure on non-Unix platforms. If you compile wxWidgets on Linux for the first time and don't like to read install instructions just do (in the base dir): > ./configure --with-mgl > make > su > make install > ldconfig > exit Afterwards you can continue with > make > su > make install > ldconfig > exit If you want to remove wxWidgets on Unix you can do this: > su > make uninstall > ldconfig > exit You can set many options to configure. Type > ./configure --help and you will get a list of supported options. * Using wxMGL library built with configure ------------------------------------------- 'make install' will install wx-config script that can (and should) be used to get compiler flags that are needed to build your program. wx-config --cxxflags will output necessary C++ compiler flags and wx-config --libs will list all needed libraries. See an example of wxWidgets application makefile: minimal: minimal.o $(CC) -o minimal minimal.o `wx-config --libs` minimal.o: minimal.cpp mondrian.xpm $(CC) `wx-config --cxxflags` -c minimal.cpp -o minimal.o * Using configure to build MS-DOS version ------------------------------------------ Even though configure is a Unix script, you can use it to build MS-DOS version of the wxMGL library. There are two possible ways to achieve this: you can either cross-compile from Unix or compile natively. Either way you will needed the DJGPP port of GCC compiler freely available from: http://www.delorie.com/djgpp/getting.html Scitech MGL must be compiled natively, and to do this you will need to download the following files (from the current/v2 and current/v2gnu directories). You should get the latest versions available rather than the exact versions shown below, they are just an example of what to look for: djdev203.zip B 1,530,778 020811 DJGPP development kit 2.03 bnu2161b.zip B 3,483,132 050708 GNU Binutils 2.16.1 for DJGPP V2 gcc344b.zip B 3,772,211 050527 GNU GCC 3.4.4 for DJGPP V2 gpp344b.zip B 4,026,725 050527 GNU C++ Compiler 3.4.4 for DJGPP V2 If you want to build wxMGL natively using the DJGPP compiler, you will have to install a couple of Unix utilities. I think the following is the minimum that will work: bsh204b.zip B 454,308 020106 GNU Bash shell 2.04 for DJGPP V2 fil41b.zip B 1,738,170 030830 GNU fileutils 4.1 for DJGPP V2 find41b.zip B 306,826 010505 GNU findutils 4.1 for DJGPP V2 grep24b.zip B 254,997 000116 GNU Grep 2.4 for DJGPP V2 mak3791b.zip B 272,798 020106 GNU Make 3.79.1 for DJGPP V2 sed414b.zip B 159,920 050331 GNU Sed 4.1.4 for DJGPP V2 shl2011b.zip B 1,195,021 020419 GNU sh-utils 2.01 for DJGPP V2 You'll probably also want a debugger: gdb611b.zip B 1,585,648 040629 GNU GDB Debugger 6.1.1 for DJGPP V2 And maybe some of these: faq230b.zip B 679,865 000203 FAQ 2.30 for DJGPP v2.03 dif281b.zip B 402,859 040911 GNU Diffutils 2.8.1 for DJGPP V2 gwk314b.zip B 968,667 050321 GNU Awk 3.1.4 for DJGPP V2 gzip135b.zip B 146,138 041215 GNU gzip 1.3.5 for DJGPP V2 lss374b.zip B 199,805 020405 GNU Less 374 for DJGPP V2 pat254b.zip B 114,250 040326 GNU Patch 2.5.4 for DJGPP V2 tar112ab.zip B 236,427 000305 GNU Tar 1.12a for DJGPP V2 whic211b.zip B 86,296 000911 GNU which 2.11 for DJGPP V2 The system you compile on must support long file names. You can use Windows 9x or an x86 version of Windows 2000/XP or later. For example: C:\>set MGL_ROOT=c:/scitech C:\>set DJGPP=c:/djgpp/djgpp.env C:\>PATH=c:\djgpp\bin C:\>set PS1=\w\$ C:\>bash c:/$ mkdir build c:/$ cd build c:/build$ ../wxWidgets/configure c:/build$ make c:/build$ cd samples/minimal c:/build/samples/minimal$ make Cross-compilation is very easy. It works like ordinary compilation with configure, you only have to specify the target: > ./configure --with-mgl --build=i586-linux --host=i586-pc-msdosdjgpp > make For this to work, you must have installed a cross compiler on your system. Ready made binaries are not available for very many systems, so usually this means you must obtain the djgpp sources and compile them yourself. NetBSD does have a binary package which can be installed with: # pkg_add cross-i386-msdosdjgpp You can also try asking on the wx-dev mailing list. If someone else has already built a cross-compiler for you platform they may be willing to send you the binaries. * Building wxMGL for MS-DOS using Watcom C/C++ ----------------------------------------------- You will need Watcom C/C++ compiler version 11 or newer (Watcom is going to be OpenSourced by SciTech, check out http://www.openwatcom.org). 1. Edit $(WXDIR)\include\wx\univ\setup.h to suit your needs (in same way as you do when compiling wxMSW). 2. Go to $(WXDIR)\src\mgl and run > wmake -f makefile.wat all 3. You can compile the samples by typing 'wmake -f makefile.mgl all' in sample directory if this file is available. If it is not, copy makefile.wat to makefile.mgl and replace the line that says !include $(WXDIR)\src\makeprog.wat with !include $(WXDIR)\src\mgl\makeprog.wat Compilation notes for MGL with gcc ---------------------------------- The mvis library doesn't compile with current versions of gcc. However wxMGL does not use this part of MGL, so it can be taken out of the compile, e.g.: --- scitech/src/makefile.orig 2004-04-15 20:36:32.000000000 +0100 +++ scitech/src/makefile 2005-04-26 01:50:12.000000000 +0100 @@ -88,7 +88,7 @@ # Target to build libraries for one compiler for SciTech MGL Graphics Library -all_mgl: $(T_PM) $(T_GCONSOLE) $(T_SNAP) $(T_TECH) $(T_MVIS) $(T_FIXED) \ +all_mgl: $(T_PM) $(T_GCONSOLE) $(T_SNAP) $(T_TECH) $(T_FIXED) \ $(T_GM) $(T_GLUT) $(T_MGL) @$(ECHO) ============================================================================= @$(ECHO) DONE: Single compiler MGL build completed successfully!
