That's a bit unexpectedly clever... So... this time: $ make clean all CPU_TARGET=powerpc OS_TARGET=linux FPC=/usr/bin/ppc386 BINUTILSPREFIX=/usr/bin/powerpc-linux-gnu-
And, just like before, it has created a load of powerpc binaries: $ file /tmp/fpc_patchdir/fpc_build/usr/bin/postw32 /tmp/fpc_patchdir/fpc_build/usr/bin/postw32: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), statically linked, stripped So I'm still puzzled that the recipe for creating a cross compiler is actually cross-compiling a compiler and cross-compiling the tools. Of course, compiler/ppcrossppc was created, but it seems as a precursor to creating all the powerpc binaries. So I still think I'm doing it wrong; was my make command line correct to produce an fpc instance that will cross-compile for powerpc-linux? Sam
