Thanks for the bug report Jeff. I confirmed it on my laptop (different software environment) too. t looks like the problem is with the combination of these two configure options:</div>

In principle that should be a valid config, I think. We'll look into it.</div>

In the mean time, can run without the --enable-mmap-logs option? I'm guessing the --without-mpi is the more important of the two for you.

<div dir="ltr">Good morning,<br>
<br>
I've been trying to build version 3.2.0 using the Ubuntu 18.04 gcc-7.5.0 compiler set along with mpich 3.3.2. My configuration command is,<br>
<br>
<span style="font-family:monospace">./configure --with-log-path=/darshan-logs --with-jobid-env=NONE CC=mpicc --enable-mmap-logs --enable-group-readable-logs --without-mpi</span><br>
<br>
The configure seems to run fine, but when I use "make", I get the following errors:<br>
<br>
<br>
<span style="font-family:monospace">$ make<br>
mpicc -DDARSHAN_CONFIG_H=\"darshan-runtime-config.h\" -I . -I. -I./../ -g -O2 -D_LARGEFILE64_SOURCE -shared -fpic -DPIC -DDARSHAN_PRELOAD -c lib/darshan-core.c -o lib/darshan-core.po<br>

^~<br>
Makefile:120: recipe for target 'lib/darshan-core.po' failed<br>
make: *** [lib/darshan-core.po] Error 1</span><br>
<br>
<br>
I've tried a few alternatives:<br>
<br>
- CC=gcc instead of CC=mpicc<br>
- not using the "--with-out-mpi" option and using CC=mpicc<br>
- Running "make clean" a few times<br>
<br>
I'm curious why, despite the "--without-mpi" option, it appears to want/need an MPI implementation (but I may be way off base here).<br>
<br>
Thanks!<br>
