wxWidgets 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 2.8.0, 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. Linux rpms are available here: http://ap1.pp.fi/djgpp/gcc/cross-compiler/index.html NetBSD has a binary package which can be installed with: # pkg_add cross-i386-msdosdjgpp For other systems you will need to obtain the djgpp sources and compile them yourself. * 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!
