Subject: [OMPI users] OpenMPI 1.8.0 + PGI 13.6 = undeclared variable __LDBL_MANT_DIG__
From: Filippo Spiga (spiga.filippo_at_[hidden])

Dear all,
  I am trying to compile Open MPI 1.8 with PGI 13.6. I am using on purpose this old version of PGI because of results and performance comparisons with old benchmarks. I run configure in this way:

./configure CC=pgcc CXX=pgCC FC=pgf90 F90=pgfortran CFLAGS="-noswitcherror" FCFLAGS="-noswitcherror" CXXFLAGS="-noswitcherror" --prefix=/usr/local/Cluster-Users/fs395/openmpi-1.8.0/pgi-13.6 --with-hwloc=internal --enable-mca-no-build=btl-usnic --with-verbs

and here where configure got stuck:

make[2]: Entering directory `/home/fs395/archive/openmpi-1.8/build/opal/datatype'
  CC opal_convertor.lo
PGC-S-0039-Use of undeclared variable __LDBL_MANT_DIG__ (../../../opal/util/arch.h: 268)
PGC/x86 Linux 13.6-0: compilation completed with severe errors
make[2]: *** [opal_convertor.lo] Error 1
make[2]: Leaving directory `/home/fs395/archive/openmpi-1.8/build/opal/datatype'
make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory `/home/fs395/archive/openmpi-1.8/build/opal'
make: *** [install-recursive] Error 1

Any suggestions? Googling does not help much...
