If you look at the .la file with a text editor it should be human- readable and
should contain a line like 'libdir=/usr/lib' which tells where libtool thought
that the real .a (or .so) library was to be installed.

I downloaded linux-gpib-3.2.09, did make and make install.
I don't see libgpib.a anywhere on my machine: not in the same
directory as libgpib.la nor where I compiled.
It appears that at some point, libgpib.a has gotten renamed to
libgpib.la in Linux GPIB package library. There has been some
references of libgpib.a in older Linux GPIB package library (at least
old version, I see a reference of it).
I have not tracked down far enough to see where the reference to
libgpib.a is made in Asyn (the assumption is that I need to change a
few lines somewhere).

I have no experience with your specific problem, but I do know that a
libXXX.la file is usually a version of a library created by an
application that uses GNU libtool before it is installed using 'make
install'.

Did you compile the National Instruments libgpib.la program yourself?
If so, try doing a 'make install' in that directory which in my
experience will cause the appropriate libgpib.a file to be created and
installed in the appropriate location. If you can't do that because you
don't have write access to the target directory you might need to re-run
the ./configure program in the GPIB build area specifying a
--prefix=/path/to/somewhere.


As an alternative, you can try looking for a hidden directory in the
same directory as the libgpib.la file which I think will contain the
actual libgpib.a file that you're looking for.

HTH,
