Here is one:

# rpm -q --qf "%{name}.%{arch}\n"  -f /lib/libgcc_s.so.1
libgcc.i386

# rpm -q --qf "%{name}.%{arch}\n"  -f \
/usr/lib/gcc/x86_64-redhat-linux/4.3.0/32/libgcc_s.so
gcc.x86_64

# ls -l /usr/lib/gcc/x86_64-redhat-linux/4.3.0/32/libgcc_s.so
/usr/lib/gcc/x86_64-redhat-linux/4.3.0/32/libgcc_s.so
-> /lib/libgcc_s.so.1

i.e. an x86_64 package depending on an i386 package.


Now try to install /lib/libgcc_s.so.1 in an x86_64 mock chroot.

I am trying to package a package which needs to build and run some bits
"-m32 compiled on x86_64". Works in a normal (multilib'ed x86_64)
environment, but I haven't managed to get this working in mock.
