P.s. Could you sent me a minimal C program linking to libc, and the

I could throw all these experiences with non standard linking in a
little tex doc. ( --nostdlib with and without
to try things out i create a static binary and coerce it to use my
C library instead of the system's one.
this is how i compile my program:
cc -g -DYP -DFreeBSD -Wall -pedantic -ansi -c -I../../libc/include nss-test.c
cc -g -nostdlib -static -L../../libc -o nss-test

I think you'll want LD_LIBRARY_PATH to be:

I don't see why since the only library I use is libc. Anyway, I tried
just for kicks and still got the same error.

I wasn't reading this too closely, but if you're trying to hand feed in
the object files, the C startup object file *MUST* come first in the list

Is that it?
Ok,

Notice here the order it links, and what files it links in. First, if
you're using nostdlib, then you have to call out your own libs, all of
them, and you forgot to do libgcc. I've been able to move the lib calls

Yes, I've done this when trying to track down buffer overflows
i'm working on the C library, and to make debuggin easy i've copied
/usr/src/lib/libc to another directory and only build libc.a.
i've also copied /usr/src/lib/csu/i386-elf to another directory and
have enabled debug symbols on both csu and libc.
