Hi,
I am trying to compile OpenMPI 1.7.3 with pgc++ (14.1) as C++ compiler. During
configure it fails with
checking if C and C++ are link compatible... no
The error from config.log is:
configure:18205: checking if C and C++ are link compatible
configure:18230: pgcc -c -DNDEBUG -fast conftest_c.c
configure:18237: $? = 0
configure:18268: pgc++ -o conftest -DNDEBUG -fast conftest.cpp conftest_c.o
>&5
conftest.cpp:
"conftest.cpp", line 21: error: "_GNU_SOURCE" is predefined; attempted
redefinition ignored
#define _GNU_SOURCE 1
^
"conftest.cpp", line 86: error: "_GNU_SOURCE" is predefined; attempted
redefinition ignored
#define _GNU_SOURCE 1
^
"conftest.cpp", line 167: warning: statement is unreachable
return 0;
^
2 errors detected in the compilation of "conftest.cpp".
When I use pgcpp instead of pgc++ OpenMPI configures and builds.
I am using
CXX=pgcpp|pgc++ CC=pgcc FC=pgfortran F77=pgfortran CFLAGS=-fast FCFLAGS=-fast
FFLAGS=-fast CXXFLAGS=-fast ./configure
--with-hwloc=/shared/apps/rhel-6.2/tools/hwloc-1.7.1 --enable-hwloc-pci
--with-cuda --prefix=/home-2/jkraus/local/openmpi-1.7.3/pgi-14.1/cuda-5.5.22
to configure OpenMPI. Any Idea what caused the errors with pgc++?
Thanks
