The only reference is here, in asyn/Makefile

ifeq ($(LINUX_GPIB),YES)
SRC_DIRS += $(ASYN)/linuxGpib
asyn_SRCS_Linux += drvLinuxGpib.c
DBD += drvLinuxGpib.dbd
asyn_LIBS += gpib
endif

You see that it does not refer explicitly to libgpib.a, it just refers to gpib.  The lib and .a are implicit.  I think it may be hard to get make to look for the .la file, even if it would work.  From Andrew's message it seems like you need to find how to turn the .la file in a .a file.

Subject: Re: Asyn 4.8 compile error with Linux GPIB

I originally installed the driver from National Instrument.  Then,
when I realized that it appears that Asyn wants to use Linux GPIB
package library, according to asynDriver documentation
(http://www.aps.anl.gov/epics/modules/soft/asyn/R4-8/asynDriver.html#Linux-gpib),
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).
