Hi What abt System.map... Can u check if symbols are there.
yes, they are, as well as in vmlinux. In my top level Makefile I find: $(NM) vmlinux | grep -v '\(compiled\)\|\(\.o$$\)\|\( [aUw] \)\|\(\.\.ng$$\)\|\(LASH[RL]DI\)' | sort > System.map but I think that in the step of making zvmlinux, unneeded symbols _may_ be stripped off, because i cannot find all the symbols in the target (in /proc/ksyms or with ksyms -a). Am i right? Thank you for answering, anyway. Cheers Ibon.

I'm trying to write a simple module for an 8xx board using the SMC2. Everything works, till I try to insmod it: I get m8xx_cpm_alloc and m8xx_cpm_hostalloc as unresolved symbols. I think that arch/ppc/8xx_io/commproc.c is properly compiled (I can see both symbols on vmlinux), but somehow the build process strips them off as they are unused (i cannot see them in /proc/ksyms in the target). Is that right? Any clue to solve it? (having them in the target kernel without modifying the original sources) Many regards. ibon -- Ibon Gotxi Garcia [off-list ref]
