Hi, Dave! Build failed on first compilation because fstat64 and stat64 defined twice. Likely because of these functions inlining in /usr/include/sys/stat.h.

I'll see if there's a more pleasant way around this, but in the meantime is it acceptable for you to pass "--enable-strict=c99" instead? The problem occurs because your compiler still responds to the "long long" type but disables the "LLONG_MAX" constant when asked for c89 mode. -Dave On Nov 14, 2012, at 4:14 PM CST, Yauheni Zelenko wrote:

Hi!

I'm trying to compile MPICH 3.0 rc1 on Red Hat Enterprise Linux 5 and compilation failed because of undefined LLONG_MAX.

LLONG_MAX definition in /usr/include/limits.h is depend on C99 condition. -std=c89 is passed to GCC.

My configure options:

./configure --prefix=${InstallDir} \ --with-pm=hydra --with-device=ch3:nemesis \ --disable-chekpointing \ --enable-strict --enable-fast=O3 \ --disable-f77 --disable-fc \ CC=/grid/common/pkgs/gcc/v4.4.5/bin/gcc CFLAGS="-m32 -fPIC" \ CPP=/grid/common/pkgs/gcc/v4.4.5/bin/cpp \ CXX=/grid/common/pkgs/gcc/v4.4.5/bin/g++ CXXFLAGS="-m32 -fPIC" \ CXXCPP=/grid/common/pkgs/gcc/v4.4.5/bin/cpp
