[fpc-pascal] Cross-compiling from 64-bit Linux to 32-bit Linux

I already had this installed and had many libraries available in /usr/lib32/

I added this and the problem was still the same. It seems the linker can't
find the libX11 library to link against. Your reply about 'locate crti.o'
gave me an idea.

I did the following...

$ locate libX11.so
/usr/lib/libX11.so
/usr/lib/libX11.so.6
/usr/lib/libX11.so.6.2.0
/usr/lib32/libX11.so.6          <-- missing unversioned libX11.so
/usr/lib32/libX11.so.6.2.0

I noticed the "unversioned" libX11.so is missing from the /usr/lib32/
directory. I manually added a symbolic link and it solved the linking -lX11
problem, but then prompted about -lXft.  I did a another locate and it had
the same problem. Added another "unversioned" symbolic for libXft.so and
now my project successfully links!!!  :-)

Thanks for getting me onto the right track.

What location in the wiki will be appropriate for such information, in case
somebody else gets stuck with cross-compiling and a similar linking problem?

I used packages.ubuntu.com to search for packages that contain libX11.so. I
noticed that only from Ubuntu 9.04 (Jaunty) does the ia32-libs include the
unversioned symbolic link. I made a mistake in my original post, I am
actually running Ubuntu 8.04.2 (Hardy) 64-bit.
