Re: PCMCIA GPIB help with linux-gpib-4.3.0

Dave,

Thanks for the tip. I changed the Makefile per your instructions, but that
didn't seem to work. As a workaround, I went into the drive directory and
commented out all of the #ifdef(GPIB_CONFIG_PCMCIA) lines and built the
kernel and that worksI think. After doing $ sudo gpib_config --minor 0, the
output of $ dmesg | grep gpib, shows:
