------- Additional Comments From docbill+bugzilla at freeshell.org  2006-09-09 08:48 -------
I've figured out this is strictly a cross compiling issue.  For example, when
building wine on an AMD64.  The following is a simple test that demonstraits the
fundamental problem.  Perhaps some form of this test could be added as a
configure test to determine when my patch is neccessary...

mkdir foo
cd foo
echo "void foo(){}" > test.c
i686-pc-linux-gnu-gcc --shared -fPIC -o libwine.so test.c
cd ..
echo "extern void foo();int main(){foo();return 0;}" > bar.c
i686-pc-linux-gnu-gcc bar.c -Lfoo -lwine

In a cross compiling envirnoment, where wine has already been installed this
will result in an error like:
/tmp/ccAZcI8P.o: In function `main':
bar.c:(.text+0x12): undefined reference to `foo'
collect2: ld returned 1 exit status

If you run an strace on the last command, you can see the problem is the cross
compile libraries are added to the search path prior to the library path
specified on the command line.  In my case I see:

execve("/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld",
["/usr/lib/gcc/x86_64-pc-linux-gnu"..., "--eh-frame-hdr", "-m", "elf_i386",
"-dynamic-linker", "/lib/ld-linux.so.2", "/usr/lib/gcc/x86_64-pc-linux-gnu"...,
"/usr/lib/gcc/x86_64-pc-linux-gnu"..., "/usr/lib/gcc/x86_64-pc-linux-gnu"...,
"-L/emul/linux/x86/lib", "-L/emul/linux/x86/usr/lib", "-Lfoo",
"-L/usr/lib/gcc/x86_64-pc-linux-g"..., "-L/usr/lib/gcc/x86_64-pc-linux-g"...,
"-L/usr/lib/gcc/x86_64-pc-linux-g"..., "-L/lib/../lib32", ...], [/* 73 vars */]) = 0
