The final linking of the resulting executable will be done on a FreeBSD machine. Som entries in "binutils/ld/configure.tgt" that may be relevant i[3456]86-*-bsd) targ_emul=i386bsd ;; i[3456]86-*-bsd386) targ_emul=i386bsd ;; i[3456]86-*-bsdi*) targ_emul=i386bsd ;; i[3456]86-*-aout) targ_emul=i386aout ;; i[3456]86-*-netbsd*) targ_emul=i386nbsd ;; i[3456]86-*-elf*) targ_emul=elf_i386 ;; i[3456]86-*-freebsdelf*) targ_emul=elf_i386 ;; The only FreeBSD entry I found was "i386-freebsdelf". Is this the target to use? I know FreeBSD can run most software that is compiled for BSDi but why not all? Is the problem shared libraries? The "*.o" files produced has to be linkable with the standard FreeBSD 2.2.1 linker. I read that ELF is supported by FreeBSD but does it require kernel or some other configuration? Will the libraries, like "libc.a" link with object files in ELF? If someone has a Web page on the topic of cross compiling to FreeBSD please let me know the URL. I have searched and searches and ...... Hmmm...I just managed to create a cross compiler for freebsdelf, after hours of trial and error, but running it on a simple program % /myinst/bin/i386-freebsdelf-gcc -o foo.o foo.c /myinst/i386-freebsdelf/lib/crt0.o: file not recognized: \ File format not recognized The "crt0.o" was copied from FreeBSD 2.2.1 so I know for sure I got something wrong ;-) /kgb
