Thank you Jeff and Min!

Would you know if MPICH 3.2 has the same issue?
I would rather use an older version instead, as long as it builds.

Many thanks,
Gus Correa

_Static_assert comes from C11.

src/include/mpir_assert.h does a direct test for C11 support based upon the GCC version, which is unsafe since ICC (and other non-GCC compilers) define these macros.

/* GCC 4.6 added support for _Static_assert:
 * http://gcc.gnu.org/gcc-4.6/changes.html */
#if (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 6)) && !defined __cplusplus
#define HAVE_C11__STATIC_ASSERT 1
#endif

MPICH needs to test for _Static_assert properly using configure.  You should file a GitHub issue to track this.

    Hi MPICH experts

    I am trying to build MPICH 3.2.1 with Intel
    compilers (icc, ifort).
    C++ is disabled.

    The configuration step goes well,
    but make fails,
    after a lot of stuff is compiled,
    with the error below (undefined reference to `_Static_assert').

    FYI, the OS is Linux Fedora Core 26:

    Linux 4.15.17-200.fc26.x86_64 #1 SMP Thu Apr 12 18:28:26 UTC 2018
    x86_64 x86_64 GNU/Linux

    The Intel compiler version is 12.1.6:
    ifort (IFORT) 12.1.6 20120928
    icc (ICC) 12.1.6 20120928

    The Intel compiler environment is set the standard way
    recommended by Intel:

    source /path/to/intel/bin/compilervars.sh intel64


    Any help is appreciated.
