[Darshan-users] undefined reference to __wrap_printf

Hi Teng,
First of all, I actually just got darshan 3.1.4 to properly generate a
log when using static linking. I'm not sure what was leading to the
problem I had earlier, but after reconfiguring and rebuilding the
library, it works for me now. I also confirmed the nightly tests were
working correctly -- the log files were going to another spot that I
wasn't expecting, so missed them the first time around. You may want to
try something similar -- just rebuilding everything from scratch and
trying again. I've also run into this problem in the past whenever I was
accidentally pointing to an mpich build that defaults to using shared
libraries rather than the static ones, so that could be another thing to
check.
As for the error you are getting with Darshan 3.1.3, I've actually never
seen someone hit that before. That error would be due to the libz
compression functions (deflate) returning some sort of error. Not
exactly sure what could cause that, but is the application opening a
really large amount of files or something like that? I suppose it's
possible the compression routines could be running out of memory if
there is too much log data they are trying to compress, but have never
seen that happen before. If you aren't already, it might be worth trying
a test program that does very basic I/O just to confirm that we can get
Darshan working. One that we frequently use is mpi-io-test -- there is a
version of this code in the darshan source @
darshan-test/regression/test-cases/src. You could try just building that
and running it (it doesn't take any command line parameters) to see if
that works?
Thanks,
--Shane
