Dear OpenMPI folks,
I tried to compile the OpenMPI version 1.5.1 on a CentOS 5.5 computer
with the default GCC shipped with the distribution, which is
gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)
The configuration failed:
....
configure:156412: checking location of libltdl
configure:156425: result: internal copy
configure:156709: WARNING: Failed to build GNU libltdl. This usually
means that something
configure:156711: WARNING: is incorrectly setup with your environment.
There may be useful information in
configure:156713: WARNING: opal/libltdl/config.log. You can also
disable GNU libltdl, which will disable
configure:156715: WARNING: dynamic shared object loading, by configuring
with --disable-dlopen.
configure:156717: error: Cannot continue
The configuration line was was follows:
$ ./configure --with-openib --with-devel-headers
--enable-contrib-no-build=vt --enable-mpi-threads CFLAGS=-O3 -ffast-math
-mtune=opteron -m32 CXXFLAGS=-O3 -ffast-math -mtune=opteron -m32
FFLAGS=-O3 -ffast-math -mtune=opteron -m32 FCFLAGS=-O3 -ffast-math
-mtune=opteron -m32 F77=gfortran LDFLAGS=-O3 -ffast-math -mtune=opteron
-m32 --prefix=/....../MPI/openmpi-1.5.1mt/linux32/gcc
With a newer version of GCC, version 4.2.4 (and also gcc version
4.5.1) the configuration completed fine.
Does there an error in my way of configuring, or is there a problem in
the configure itself? I think the non-ability to configure and build
OpenMPI with the default compiler on CentOS 5.5 is still a problem, also
other versions of GCC seem not to have the same issue.
Best wishes,
Paul
