Gcc compiler not finding object files

kareempj · 04-20-2012, 11:55 AM

Hey guys, I am having another problem with my gcc compiler. I has been installed correctly yet when I try to compile I keep getting this error:

/export/software/gcc-4.5.1/libexec/gcc/x86_64-unknown-linux-gnu/4.5.1/f951: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory

However when I go to that location I am seeing the libmpc.so.2 file so I am wondering why I keep getting this error when trying to compile!

Please any help given will be greatly appreciated

can you show us the full command? Maybe a -L flag is missing.

The command I am issuing is gcc test.c, where test is a simple hello world program!

there is a libmpc related package. I do not know your os, but I think this package is missing.

what operating system is this and HOW did you install gcc

for example :
IF this is a red hat based os like fedora
you NEED to install the development group and the development libraries
not just gcc ONLY

without knowing the needed information all i can say is

install the development environment for your distro
how you do that depends on what you are using

If your libraries are in a non-standard location (i.e. not /usr/lib, /usr/lib64 or the like) you need to set LD_LIBRARY_PATH to point to them, e.g.:

export LD_LIBRARY_PATH=/export/software/gcc-4.5.1/lib64 # note (change lib64 to lib if on a 32 bit system).

To make ld always search in a particular directory for libraries, you can modify /etc/ld.so.conf.
