I am attempting to install an application. During compilation it fails with the following error:

/usr/bin/ld: cannot find -lemu

I have installed the libemu library, and it now currently resides in /opt/libemu/. However, when I try and compile my application the library is not found. Is there any way to correct this?

EDIT: It also looks like the make is resulting in:
It also looks like the make file is compiling with the following:

gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions 
build/temp.linux-x86_64-2.6/libemu_module.o 
-L/opt/libemu/lib -lemu -o build/lib.linux-x86_64-2.6/libemu.so

I have tried setting my LD_LIBRARY_PATH to /opt/libemu, still doesn’t work – fails with the error mentioned above.

    You need to tell the linker where it is:

    gcc  stuff -L/opt/libemu -lemu

    or:

    gcc  stuff /opt/libemu/libemu.a

    where stuff is your normal compile/link options files etc.

    You can also specify library paths in the LIBRARY_PATH environment variable:

    LIBRARY_PATH=/opt/libemu
export LIBRARY_PATH

    before you run your build. Yet another option is to see where gcc looks for libraries by running:

    gcc --print-search-dirs

    and put your library in one of the listed directories.

    Edit: It is really not clear from your latest info what you are trying to build. Are you trying to turn a static library into a shared library? Most important – What is the exact filename of the library file you have copied into the /opt/libemu directory?
