Hello MPICH community. Recently we had a report of a regression on the MVAPICH discuss list and I've found that the regression appears in MPICH-3.1.2 itself.

We plan on just removing the _XOPEN_SOURCE lines but thought that you'd like to know about this so that it could be fixed in MPICH as well. Thanks!

so, on solaris we needed to put back _XOPEN_SOURCE lines with --enable-strict in order to bring in pread/pwrite declarations, I think. but i had forgotten about the caddr_t time compile issue. thanks for the report. ==rob

Thanks for the report Adam. We'll review the fix and ticket and see what we do to prevent this from appearing in future releases.

Hello MVAPICH team, While building MV2-2.1a on our systems, I'm getting the following error:

In file included from /usr/include/linux/lustre_user.h:46, from /usr/include/lustre/lustre_user.h:54, from adio/ad_lustre/ad_lustre.h:30, from adio/ad_lustre/ad_lustre_rwcontig.c:20: /usr/include/sys/quota.h:221: error: expected declaration specifiers or '...' before 'caddr_t' make[3]: *** [adio/ad_lustre/ad_lustre_rwcontig.lo] Error 1

This happens while trying to build mvapich2-2.1a/src/mpi/romio/adio/ad_lustre/ad_lustre_rwcontig.c.

This is due to an incompatibility with Lustre 2.4. I first saw this with MV2-1.9, it was fixed in MV2-2.0, but now it's back with MV2-2.1a.

The problem lines are here, which can be found starting at line 5:

#ifdef _STDC_C99 #define _XOPEN_SOURCE 600 #else #define _XOPEN_SOURCE 500 #endif

The solution before was to not define _XOPEN_SOURCE in this file. If I comment out these definitions, I've verified that MV2-2.1a builds.

Here is a related MPICH ticket reported by Yan Li and Jerome Vienne:
