LD_LIBRARY_PATH doesn't seem to work

Question

I\'m trying to compile a test file:

gcc -o test  test.c -lg2c

but I get the error:

/usr/bin/ld: cannot find -lg2c

Answer 1

Make sure that you export LD_LIBRARY_PATH after modifying it. Otherwise GCC won't be able to see the modified version.

LD_LIBRARY_PATH=/usr/lib/gcc/x86_64-redhat-linux/3.4.6:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
gcc -o test test.c -lg2c
