Re: can't find crt1.o. egcs powerpc-linux cross-compile problem.

["Charles Gauthier" <Charles.Gauthier@iit.nrc.ca>]

WARNING: I do not really know what I am talking about! But here is my guess:

crt1.o is on your PowerPC Linux box ;-)

It's a binary that came with the OS. You were expected to copy it to your host
machine. Presummably, the source code is available in the Linux source
distribution (don't ask me which one.)

My guess is based on the idea that -target=powerpc-linux picked up
egcs/gcc/config/rs6000/linux.h, which includes egcs/gcc/config/rs6000/sysv4.h.
This latter header file has:

#ifndef STARTFILE_LINUX_SPEC
#define STARTFILE_LINUX_SPEC "\
%{!shared: %{pg:gcrt1.o%s} %{!pg:%{p:gcrt1.o%s} %{!p:crt1.o%s}}} \
%{mnewlib: ecrti.o%s} \
%{!mnewlib: crti.o%s %{!shared:crtbegin.o%s} %{shared:crtbeginS.o%s}}"
#endif

which is were the attemp to link with crt1.o comes from.

Hope this helps.

BTW, you might be able to provide a stub to satisfy the linker during
configuration. Look at newlib/newlib/libc/sys/rtems/crt0.c for an idea.
