Hello MVAPICH team,
I was trying to build shared libraries for MVAPICH2-1.4.1 using the
tarball downloaded from the MVAPICH webpage. I am using the following
configure command:
./configure \
--prefix=/usr/local/tools/mvapich2-intel-debug-1.4.1 \
--enable-sharedlibs=gcc \
--enable-f77 --enable-f90 --enable-cxx \
--enable-fast=O0 --enable-g=dbg
--enable-error-checking=runtime --enable-error-messages=all
--enable-nmpi-as-mpi \
--enable-debuginfo \
--with-pmi=slurm --with-pm=no \
--with-rdma=gen2 --with-ib-include=/usr/include
--with-ib-lib=/usr/lib64 \
--enable-registration-cache \
--enable-romio --with-file-system=lustre+nfs+ufs \
--disable-mpe --without-mpe && \
The build seems to complete, but the shared objects are missing from the
lib directory. When I trace back through the build output, I see the
following error.
make[2]: Entering directory
`/tmp/dpkg-mkdeb.trTLU12767/src/build-mvapich-long-path-hack-enabled-ofa-intel-debug'
(cd lib &&
/tmp/dpkg-mkdeb.trTLU12767/src/build-mvapich-long-path-hack-enabled-ofa-intel-debug/src/util/createshlib
--mode=link -version-info "1:1" -o libmpich.la -rpath
/usr/local/tools/mvapich2-intel-debug-1.4.1/lib -lpmi -lpthread
-lrdmacm -libverbs -libumad -lrt -ldflags "" -lpmi -lpthread
-lrdmacm -libverbs -libumad -lrt )
/usr/bin/ld: cannot find -ldflags
It seems that createshlib should be stripping the -ldflags as an input
parameter, but instead it must be passing it on to the linker, which
then fails to build the shared object.
