I'm trying to use a FC6 64bit to AIX 5.3.0 gcc crosscompiler I built. The
program I'm compiling is just hello world:
#include <stdio.h>
int main()
{
printf("Hello world\n");
return 0;
}
The command line I'm using to compile is:
[EMAIL PROTECTED] ~]$ powerpc-ibm-aix5.3.0-gcc test.c
When I try to run the resultant binary on an AIX 5.3.0 system is:
bash-2.05b# ./a.out
exec(): 0509-036 Cannot load program ./a.out because of the following errors:
0509-150 Dependent module libc.a(shr.o) could not be loaded.
0509-022 Cannot load module libc.a(shr.o).
0509-026 System error: A file or directory in the path name does not
exist.
Running objdump on the exectuable shows that the rpath is referring to the
library paths on the host system, not the target system:
[EMAIL PROTECTED] ~]$ powerpc-ibm-aix5.3.0-objdump -s a.out | grep -A20 -B2

I compiled binutils with the following options:
../configure --target=powerpc-ibm-aix5.3.0 x86_64-redhat-linux --prefix=/usr
--exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc
--datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64
--libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com
--mandir=/usr/share/man --infodir=/usr/share/info --enable-shared
--disable-werror --with-build-sysroot=/usr/powerpc-ibm-aix5.3.0/sys-root
--with-sysroot=/usr/powerpc-ibm-aix5.3.0/sys-root
Since I built binutils with the sysroot option, and I verified that gcc is
passing --sysroot=/usr/powerpc-ibm-aix5.3.0/sys-root, the rpath should have that
part of the paths stripped out. Preferrably, any paths that are outside of the
sysroot should not be included either.
Now if I pass rpath to the linker, the resulting binary works:
[EMAIL PROTECTED] ~]$ powerpc-ibm-aix5.3.0-gcc -Wl,-rpath,/usr/lib test.c
On AIX system:
bash-2.05b# ./a.out
Hello world
It looks like the problematic code is in aix.em:
if (command_line_blibpath != NULL)
libpath = command_line_blibpath;
else if (command_line.rpath != NULL)
libpath = command_line.rpath;
else if (search_head == NULL)
libpath = (char *) "";
else
{
size_t len;
search_dirs_type *search;
len = strlen (search_head->name);
libpath = xmalloc (len + 1);
strcpy (libpath, search_head->name);
for (search = search_head->next; search != NULL; search = search->next)
{
size_t nlen;
nlen = strlen (search->name);
libpath = xrealloc (libpath, len + nlen + 2);
libpath[len] = ':';
strcpy (libpath + len + 1, search->name);
len += nlen + 1;
}
}
