dear sir:
i'm using aocc v3 to compile the openmpi v4.1.0 which is okay to build the openmpi. however, i used the openmpi with aocc to compile the hdf5 v1.12.0. it encountered the following problems :
make[3]: Entering directory '/home/hctseng/src/hdf5-1.12.0/tools/src/h5diff'
CCLD h5diff
ld.lld: error: undefined symbol: nl_socket_alloc

i'm wondering how to correctly use the aocc3 to compile hdf5?
ps : i'm using the following options to compile openmpi :
$ ./configure --prefix=/opt/ompi/4.1.0_aocc_3.0.0 CC=clang CXX=clang++ FC=flang --enable-mpi-fortran --enable-shared=yes --enable-static=yes --enable-mpi1-compatibility --enable-mpi-cxx --enable-mca-no-build=btl-uct --enable-mca-no-build=btl-uct --with-pmix --with-hcoll=/opt/mellanox/hcoll --with-knem=/opt/knem-1.1.4.90mlnx1 --with-xpmem=/opt/xpmem --with-verbs=yes
it went though well.
using the following options to compile hdf5 :
$ ./configure --prefix=/opt/hdf5/1.12.0_ompi_4.1.0_aocc_3.0.0 CC=mpicc CXX=mpicxx FC=mpifort CFLAGS="-fPIC" CXXFLAGS="-fPIC" FCFLAGS="-fPIC" --enable-static --enable-shared --enable-parallel --enable-static-exec --enable-hl --enable-cxx --enable-unsupported
it failed with the libibverbs.a
could any guru help this? thank you in advance.
best, sam
