[mpich-discuss] Error building mpich-3.1.2 on Solaris 10 with gcc-4.9.0

[Siegmar Gross]

Hi,

thank you very much for all answers to my problems building
MPICH on Solaris with gcc-4.9.0. Today I tried to build
mpich-master-v3.2a1. Unfortunately I have had the same problems.

I have attached the files in the archive
mpich-3.2-SunOS.sparc.64_gcc_only-m64.tar.gz

It was a little bit more complicated to get this one as far as
the build with just "CFLAGS=-m64". Adding "-D__EXTENSIONS__" broke
the build process. Adding "-D_XOPEN_SOURCE=500" didn't solve the
problem, because Solaris expects "-D_XOPEN_SOURCE=600". Using this
flag wasn't helpful, because you redefined it to "500" in file
mpich-master-v3.2a1/src/mpi/romio/adio/common/ad_read.c, so that I
had to add "-D_STDC_C99" to keep "600". Another problem came from
file /usr/include/sys/statvfs.h ("FSTYPSZ" wasn't defined). Looking
into the file showed the following.

...
#define _FSTYPSZ        16
#if !defined(_XPG4_2) || defined(__EXTENSIONS__)
#ifndef FSTYPSZ
#define FSTYPSZ _FSTYPSZ
#endif
...

Finally I could build MPICH with "CFLAGS=-m64 -std=c99 -D_STDC_C99
-D_POSIX_C_SOURCE=200112L -D_XOPEN_SOURCE=600 -DFSTYPSZ=_FSTYPSZ"
to the same point as with "CFLAGS=-m64". In both cases libmpicxx.so
wasn't available. I have attached the files for this build process
in the archive mpich-3.2-SunOS.sparc.64_gcc.tar.gz. Please let me
know if you need anything else.

Kind regards

Siegmar
