Hi everyone,


I built Darshan 3.1.4 with OpenMPI 2.0.2 and gcc 7.2.1 using the following configure flags:


./configure --with-mem-align=8 --with-log-path-by-env=DARSHAN_LOGPATH --with-jobid-env=NONE CC=mpicc --prefix=/usr/local/darshan-3.1.4-ompi


I have also attached the config.log file. When I run my application with LD_PRELOAD, Darshan does not create any trace file and neither does it complain:


[miahw@bedale bin]$ export DARSHAN_LOGPATH=.
[miahw@bedale bin]$ LD_PRELOAD=/usr/local/darshan-3.1.4-ompi/lib/libdarshan.so mpirun -n 4 ./bt.A.4.mpi_io_full
[ ... lots of application output ... ]
[miahw@bedale bin]$ ls
bt.A.4  bt.A.4.mpi_io_full  btio.full.out  inputbt.data

As you can see, there is no trace file in the current working directory. Any help will be greatly appreciated.

Thanks in advance,
Wadud.
