[SOLVED] GCC multilib: cannot find shared library

Question

Hi,
I'm trying to compile a systemc program to a 32-bit executable on arch x86_64.  I'm using GCC multilib.  Program compiles fine, but I get the following error when trying to run.
/home/[myusername]/workspace/systemc_test/Debug/systemc_test: error while loading shared libraries: libsystemc-2.3.1.so: cannot open shared object file: No such file or directory
Compiler:
g++ -std=c++0x -DSC_INCLUDE_DYNAMIC_PROCESSES -I/usr/local/systemc/include -O0 -g3 -Wall -c -fmessage-length=0 -m32 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o" "../main.cpp"
Linker:
g++ -L/usr/local/systemc/lib-linux -m32 -o "systemc_test" ./main.o -lsystemc
ls /usr/local/systemc/lib-linux/
libsystemc-2.3.1.so  libsystemc.a  libsystemc.la  libsystemc.so  pkgconfig
What am I doing wrong?  For the record, this works fine on Ubuntu (64-bit with multilib) using the same version of the systemc library, compiled and installed in exactly the same manner.
Thanks!

You're correct -- doesn't find that path.
ldd systemc_test
linux-gate.so.1 (0xf77ac000)
    libsystemc-2.3.1.so => not found
    libstdc++.so.6 => /usr/lib32/libstdc++.so.6 (0xf768f000)
    libm.so.6 => /usr/lib32/libm.so.6 (0xf7643000)
    libgcc_s.so.1 => /usr/lib32/libgcc_s.so.1 (0xf7628000)
    libc.so.6 => /usr/lib32/libc.so.6 (0xf7465000)
    /lib/ld-linux.so.2 (0xf77ad000)
Adding /usr/local/systemc/lib-linux to LD_LIBRARY_PATH solves the problem.  I used a script under /etc/profile.d/ to set this at session start, so I now consider this solved.  Out of curiousity, is it possible to avoid having to do this?
