The problem exists in PGI 18 but not PGI 17. This seems like a PGI bug rather than an MPICH one. Jeff On Fri, Jul 20, 2018 at 8:24 AM, Jeff Layton <[email protected]> wrote:

I fixed this problem and I get the exact same error. Again, I grepped config.log and found the following.

I'm not an expert but it looks like configure sends an unknown option to pgcc (-qversion). Then there appear to be some problems in mpich when built with pgcc.

Any comments or thoughts?

Thanks!

Dooh. Thanks - I'll try this and see what happens.

Thanks!

Hello,

I'm trying to build mpich-3.2.1 with the PGI 18.4 Community Edition compilers. However, I get an error when running configure. The configure line is,

./configure --prefix=/home/laytonjb/bin/pgi-18.4-mpich-3.2.1

The error I get is,

[laytonjb@laytonjb-Lenovo-G50-45 mpich-3.2.1]$ ./conf.jeff Configuring MPICH version 3.2.1 with '--prefix=/home/laytonjb/bin/pgi-18.4-mpich-3.2.1' 'CC=/opt/pgi/linux86-64/18.4/bin/pgcc' 'CPP=/opt/pgi/linux86-64/18.4/bin/pgcc' 'CXX=/opt/pgi/linux86-64/18.4/bin/pgg++' 'FC=/opt/pgi/linux86-64/18.4/bin/pgfortran'

pgg++ seems to be typo, duno whether this is related.

I've briefly looked through the config.log and this is all that stands out:

$ grep -i error config.log pgcc-Error-Unknown switch: -qversion PGC/x86-64 Linux 18.4-0: compilation completed with severe errors PGC-S-0035-Syntax error: Recovery attempted by replacing identifier error by ';' (conftest.c: 14) PGC/x86-64 Linux 18.4-0: compilation completed with severe errors | Syntax error PGC-S-0035-Syntax error: Recovery attempted by replacing identifier error by ';' (conftest.c: 14) PGC/x86-64 Linux 18.4-0: compilation completed with severe errors | Syntax error configure:5951: error: in `/home/laytonjb/src/mpich-3.2.1': configure:5953: error: C preprocessor "/opt/pgi/linux86-64/18.4/bin/pgcc" fails sanity check HAVE_ERROR_CHECKING='' MPI_MAX_ERROR_STRING=''

I'm not sure how to fix this error. I've attached the config.log file in case this helps.

Thanks for any and all help.

Jeff
