LIB_PATH for cross compiling

LIB_PATH for cross compiling

[Michael Habermann]

Hi!

I cross compile from i386 to ppc. If I compile a simple C program, the
linker searchs the libc.so.6 in the /lib path instead of the
/usr/local/powerpc-linux/lib. If I specify the path explicit, it works.

I've tried to make changes in binutils/ld/Makefile and
binutils/ld/genscripts, but found no solution.

How can I change the search path of the linker so that I can simply replace
gcc with powerpc-linux-gcc for simple programs?

I know the question has been asked several times before, but I've not found
an answer in the mailing list that I can use.

I think you need to edit the file "/usr/local/powerpc-linux/lib/libc.so".
You will find it is a text file that looks like this:

/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a )

change "/lib" and "/usr/lib" to be "/usr/local/powerpc-linux/lib" in the above
file (do it automatically with a script as part of the installation of glibc).
Cheers!

Thank you, thank you! This solved the problem.
