The good news first: it compiles now. The problem I described in the previous mail was that libjc was linked with the option "-module" (so it can be dlopen()ed) and this is not portable. I removed the -module and now it compiles.
I stripped out lots of ELF specific stuff, so my version could be interesting for a port to windows too. I just don't want to commit it to "trunk" yet because it's completely untested. @Archie Cobbs: Is the "-module" really important for libjc? If yes we'd have to find a portable solution for this... To make it compile I left the funtion "_jc_dynamic_invoke(...)" in the file "libjc/arc/ppc/arch_functions.c" empty, but this function is needed to run JCHEVM (it calls C functions and is needed for JNI AFAICS). Maybe somebody with more PPC experience can help me with porting this function from i386. Cheers, David.
