[pkoning2]

Downloaded ior 3.3.0, tried ./configure, which failed:

See config.log' for more details
Tried ./configure --without-mpiio -- that switch was accepted but the terminal output is identical, same failure to configure.

Can you share config.log?

[pkoning2]

Here it is.
config.log

Error message is quite clear. You need either Open MPI or MPICH installed to build.

[pkoning2]

Ok, but isn't the intent of --without-mpiio to say "I don't want to use Open MPI"?

[JulianKunkel]

Good guess but this can be easily misread. It is about MPI IO not about MPI itself. No worries. Is your goal to really build without MPI ? Paul Koning ***@***.***> schrieb am Do., 29. Juli 2021, 20:25:

My goal was simply to do a basic build to explore the tool for the first time. I don't know MPI. Will read the documentation more carefully. Thanks!

[pkoning2]

Hm. The documentation says to run configure as usual, no mention of any dependencies. What are they (and if not obvious, where can these be found)?

[JulianKunkel]

I suppose you did resolve the issue?
