Subject: Re: [OMPI users] Can not turn off C++ build.

Hi Jeff,
   Thanks. I am just running the Intel 13.0.1 compiler on the Quarry
cluster at IU. It would be very odd to have a serious issue without
users complaining. I tried running it again with C++ turned on with:

  ./configure CC=icc CFLAGS="-xT -O2" F77=ifort FFLAGS="-xT -O2"
FC=ifort FCFLAGS="-xT -O2" CXX=icpc --enable-static --disable-shared
--with-threads=posix --prefix=/N/soft/rhel6/openmpi/intel/openmpi-1.6.3

The block ends very similarly to how it acted with g++:

*** C++ compiler and preprocessor
checking whether we are using the GNU C++ compiler... yes
checking whether icpc accepts -g... yes
checking dependency style of icpc... gcc3
checking how to run the C++ preprocessor... icpc -E
checking for the C++ compiler vendor... intel
checking if icpc supports -finline-functions... yes
configure: WARNING: -finline-functions has been added to CXXFLAGS
checking if C and C++ are link compatible... yes
checking for C++ optimization flags... -O3 -DNDEBUG -finline-functions
checking size of bool... 0
checking alignment of bool... configure: WARNING: *** Problem running
configure test!
configure: WARNING: *** See config.log for details.
configure: error: *** Cannot continue.

Checking the config.log and picking it up around config 16462:
