[Averty, B. <bru...@ed...>]

Hi,

got installed in april the gpiblib 3.1.92 with the National Instruments
PCI-GPIB card, works great !!! (good job, total respect)

I have download the  3.1.97 last week, and boom !! error : "libgpib: error
locking board mutex!"

I have the same error what ever I use (my own programs, ibtest, ...)

any ideas ?

You're probably still using part of 3.1.92 somewhere.  Make sure your=20
programs are linking against libgpib-3.1.97, delete all files installed=20
from the old library, and delete any old gpib modules from=20
/lib/modules/<kernel_version>/misc.

Err, nevermind about that, I should improve those error messages.  You=20
need to run gpib_config now after loading the kernel modules.  See the=20
INSTALL file.
