[Darshan-users] Trouble building 3.2.0

[Carns, Philip H.]

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:

--enable-mmap-logs
--without-mpi

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

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.

thanks,
-Phil

Subject: [Darshan-users] Trouble building 3.2.0

Good morning,

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,

./configure --with-log-path=/darshan-logs --with-jobid-env=NONE CC=mpicc --enable-mmap-logs --enable-group-readable-logs --without-mpi

The configure seems to run fine, but when I use "make", I get the following errors:


$ make
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
lib/darshan-core.c: In function ‘darshan_init_mmap_log’:

Makefile:120: recipe for target 'lib/darshan-core.po' failed
make: *** [lib/darshan-core.po] Error 1


I've tried a few alternatives:

- CC=gcc instead of CC=mpicc
- not using the "--with-out-mpi" option and using CC=mpicc
- Running "make clean" a few times

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).

Thanks!

Jeff
