Question

I am using gcc to compile a program which I need to link to a C library with non-standard name; it is called stuff.a instead of libstuff.a.

I cannot change the name of the file (permission issues).

I don’t want to include the full library (i.e. using gcc program.c stuff.a -oprogram)

I want to compile as gcc program.c -L/path/to/library/ -lstuff -oprogram but gcc will not find the library (because it is not called libstuff.a).

I am working on a Linux box.

How can I get the (dynamic) linking done?

EDIT:

Thank you all, and my apologies for a poorly worded question.

I did not even have a shared object (I thought I could link dynamically to an *.a file), so this confused many of you. Again, apologies for my ignorance.

What I ended up doing is creating the shared object in a local directory, appending the location to my LD_LIBRARY_PATH environment variable, and linking again.

It works like a charm (from 1.3M executable down to 5.8K).

Thanks again.

Assuming that a shared object version of the static library does not exist, it might be necessary to create one. Remember that the static library stuff.a is just an ar archive.

ar -x stuff.a
gcc -shared *.o -o libstuff.so

This assumes you want to link against it as a shared library and not simply compile it into your binary.
