NI4882 GPIB support for Linux 64bit?

[Dennis Nicklaus <nicklaus@fnal.gov>]

I'm trying to build asyn support for arch = linux-x86_64 to use with GPIB over ethernet.

I seem to be bumping into a problem where it is looking for libgpibapi.a and that library only exists in the 32bit NI library:

$ ls /usr/local/natinst/ni4882/lib
cib.o               liblvgpibconf.so.15.1.0*   libniGPIBsys.so.15.1.0*
libgpibapi.so.15.1.0*       libni4882.so.15.1.0*       ni4882.o
libgpibenumsvc.so.15.1.0*  libni488config.so.15.1.0*

ls /usr/local/natinst/ni4882/lib64
libni4882.so.15.1.0*  libni488config.so.15.1.0*  libniGPIBsys.so.15.1.0*  ni4882.o

If I point the asyn Makefile at  /usr/local/natinst/ni4882/lib64, it complains it can't find libgpibapi.a and if I point it at /usr/local/natinst/ni4882/lib (32 bit version), it rightly complains that libgpibapi.so is incompatible.

Am I forced to build everything for 32bit if I need GPIB asyn?
