Most likely it was compiled with gcc ...
Running "strings -a library.a" may reveal more.

The most relevant info here is the *exact* error message.
The next most relevant are the failing link line, the version of
gcc you are using, and whether the library is "C" or "C++".

Unfortunately, you didn't provide any relevant details.
Perhaps you should read this:

Assuming the library is C++, the most likely problem is that you
are trying to link g++-3.x compiled code with g++-2.9x.

Code compiled by different versions of g++ is not link-compatible.
If you want to use that library, you must compile/link your code
with the same version of g++ the library was compiled with (the
strings command above will tell you which versions that was).

Possible; unlikely.
