incorrect library path in 3.0.1?

[Nick Papadonis <npapadon at yahoo dot com>]

Just a note on this.  I have experienced the same problem with GCC
3.0.

I believe it is from the GCC 3.0 compilation.  I set the install prefix
for /usr/local/lib, however this is not reflected in the compiled gcc
executable.  Is there a build problem here?  Setting the
LD_LIBRARY_PATH=/usr/local/lib solves the problem.

$ 1014 ~/build/vx5r -> gcc --version
3.0.1

$ 1006 ~ -> gcc -print-search-dirs
install: /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/
programs: =/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/:/usr/lib/gcc/i686-pc-linux-gnu/3.0.1/:/usr/lib/gcc/i686-pc-linux-gnu/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/../../../../i686-pc-linux-gnu/bin/i686-pc-linux-gnu/3.0.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/../../../../i686-pc-linux-gnu/bin/

Hi Ed

If you add '/usr/local/lib' to your LD_LIBRARY_PATH environment variable
that should allow the shared objects (libraries) to get picked up.

LD_LIBRARY_PATH is usually defined in your '.cshrc' script (or whatever you
use).

Another answer is to rename the GCC '.so' modules to '.so.save' and then the
loader will pick up the '.a' versions of the libraries and statically link
them with your program. Makes programs bigger but they have less libraries
to lose!
