First, you misunderstand AIX. On AIX shared libraries *are*
archives. Shared libraries are archives of shared objects and non-shared
objects. If you copied libc.a from AIX, it is a shared library.


Understood. I didn't know that.

	Second, collect2.c reverts to scanning libraries with "nm" when
cross-compiling:

#ifdef CROSS_COMPILE
#undef OBJECT_FORMAT_COFF
#undef MD_EXEC_PREFIX
#undef REAL_LD_FILE_NAME
#undef REAL_NM_FILE_NAME
#undef REAL_STRIP_FILE_NAME
#endif


What then must I do to get this cross toolchain to work? The target nm command doesn't understand the file format of libc.a:

/root # /usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm /usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/lib/libc.a

frexp.o:
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: frexp.o: no symbols

...

ptrgl_64_64.o:
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: ptrgl_64_64.o: no symbols
/usr/local/cross-tools/powerpc-ibm-aix4.2.1.0/bin/nm: : File format not recognized


Thanks David.
