Hi,

I want to crosscompile Allegro for using it with djgpp under Debian Gnu/Linux. I have a working crosscompiler ($ i386-pc-msdosdjgpp-gcc -v Using built-in specs. Target: i386-pc-msdosdjgpp Configured with: ./configure -v --prefix=/usr --target=i386-pc-msdosdjgpp --disable-nls --host=i686-pc-linux-gnu --enable-languages=c,c++,fortran --enable-version-specific-runtime-libs --with-headers=/usr/i386-pc-msdosdjgpp/include Thread model: single gcc version 4.2.2 ) and have executed "fix.sh djgpp", patched xmake.sh to use ff. values:

XC_PATH=/usr/local/i386-pc-msdosdjgpp/ XPREFIX=i386-pc-msdosdjgpp- INSTALL_BASE=/usr/local/i386-pc-msdosdjgpp .. CPATH=$CPATH:$XC_PATH/include export CROSSCOMPILE MINGDIR DJDIR NATIVEPATH PATH XPREFIX CPATH

Then the "xmake.sh depend" was processed successfully. But if I try to run "xmake.sh" or "xmake.sh all" there I got the errors: ... src/i386/icsprite.c: In function 'compile_sprite': src/i386/icsprite.c:71: warning: implicit declaration of function '_unix_get_page_size' src/i386/icsprite.c:71: warning: implicit declaration of function 'mmap' src/i386/icsprite.c:71: error: 'MAP_SHARED' undeclared (first use in this function) src/i386/icsprite.c:71: error: (Each undeclared identifier is reported only oncesrc/i386/icsprite.c:71: error: for each function it appears in.) src/i386/icsprite.c:71: warning: assignment makes pointer from integer without a cast src/i386/icsprite.c:71: warning: assignment makes pointer from integer without a cast src/i386/icsprite.c:71: warning: implicit declaration of function 'mremap' src/i386/icsprite.c:71: error: 'MREMAP_MAYMOVE' undeclared (first use in this function) src/i386/icsprite.c:71: warning: assignment makes pointer from integer without a cast ... make: *\ [obj/djgpp/alleg/icsprite.o] Error 1

I downloaded allegro as allegro-4.2.2.tar.gz from your Website.

Please could you help me to fix this possible bug?

Since the problem is in ASM blitter code you can try to dissable ASM. I'm not sure how is that done for crosscompiling. I guess you should pass ALLEGRO_USE_C=1 (x)make.

The problem seem to be at the beginning of src/i386/opcodes.h. Apparently, gcc #defines linux even when crosscompiling for DOS. You can easily fix that until a solution is found.

Since the problem is in ASM blitter code you can try to disable ASM. I'm not sure how is that done for crosscompiling. I guess you should pass ALLEGRO_USE_C=1 (x)make.
