People on IRC might already have noticed, but I was playing a bit with crosscompiling from mingw->*nix. The first successes are in, though this is only the initial procedure.
To compile linux lazarus on windows: (the procedure from freebsd will not differ much, the cprt0 copying is not needed for FreeBSD) Requirements: - FPC 1.9.6 or higher. 1.9.4 migh work, but untested. - ftp://freepascal.stack.nl/pub/fpc/contrib/cross/mingw/binutils-2.15-win32-i386-linux.zip - A FPC CVS repository. (anything 1.9.6+ that is buildable will do) - a lazarus tree. (anything buildable from the same period will do) - Lots of libraries from the target linux system. One of the FPC servers is some SUSE, that's what I used, but it should be pretty generic. - Assume normally installed FPC, and being able to build e.g. lazarus on windows - some knowledge about how libs are named on linux. Additional docs: - lazarus docs, specially what libs are needed to build lazarus - buildfaq http://www.stack.nl/~marcov/buildfaq.pdf can be examined if something goes wrong and for background info. 1) Download ftp://freepascal.stack.nl/pub/fpc/contrib/cross/mingw/binutils-2.15-win32-i386-linux.zip 2) extract it and move the i386* files to <fpcbindir>\bin\i386-win32 (e.g. c:\pp\bin\i386\win32) 3) enter FPC source dir 4) make clean 5) make OS_TARGET=linux all 6) make OS_TARGET=linux install INSTALL_PREFIX=<fpcbindir> 7) prepare the lib directory as in below instructions, I used d:\fpc\linuxlib to store them. 8) go to <fpcbindir>\units\i386-linux\rtl and copy cprt21.o over cprt0.o 9) enter lazarus dir 10) edit lazarus.pp and add {$linklib dl} and {$linklib gmodule} somewhere in the source. 11) (on one line) make OS_TARGET=linux all OPT="-gl -Fld:\fpc\linuxlib -Xr/usr/lib -FL/usr/lib/ld-linux.so.2 " If some linker error (most specifically linker can't find -l<something>) then 12) manually edit link.res if needed (see below for gtk remarks) and adapt the -l<x> names at the bottom of the files. I had to add -1.2 to all gtk libs, to keep them apart from gtk2 13) run ppas.bat to restart the linker ----------- Libraries These are the libraries I collected for both lazarus and the textmode IDE (lazarus doesn't need pthread). I gathered these from the target system, and renamed all from lib<name>.so.x.y to lib<name>.so. libgcc.a and a few others are easiest found by doing gcc -v and look for a line like: "Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.5/specs" then some of the libs are in /usr/lib/gcc-lib/i486-linux/3.3.5/ Some other good locations are /lib /usr/lib /usr/local/lib /usr/x11R6/lib and /opt/gnome/lib libpthread.so.0 libdl.so libc.so ld-linux.so.2 crtbegin.o crtbeginS.o crtbeginT.o crtend.o crtendS.o crtn.o crti.o libgcc.a libX11.so libXi.so libglib-1.2.so libgmodule-1.2.so.0 libgdk_pixbuf.so libgdk-1.2.so libgtk-1.2.so libXext.so libm.so libdl.so.2 libgmodule-1.2.so Note that some files exist twice, with a .so.x suffix and just .so. These are required because some other lib had a dependancy to that exact name (so the form lib<name>.so.x) we can't symlink on windows, so I simply copied it. Making mistakes with renaming is not that bad, there will be chances to fix it. Make sure all crt* and a file "libc.so" are available before your first attempt, otherwise generating link.res will go wrong. (Yes, Peter, that was my fault with the crt<x> files, forgot the -Fl :-) libgcc.a is the only .a In my case compilation for step 11 will go ok, but the linker will complain it can't find libgtk.so and the other libraries marked with -1.2 This is because on the target system, libgtk is gtk 2.0, while we want gtk1.2 for lazarus. To fix this I manually added -1.2 to the corresponding -l lines in the bottom of the link.res file that was generated by step 11 and reran ppas.bat I crosscompiled the texmode IDE also this way, same tricks, only you need ncurses as extra lib. I also crosscompiled the threading demo "tmt1" _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
