[gmx-users] MDRun Compile issue

[Weiner, Michael]

I am trying to build gromacs 2018.2 on an intel-based HPC that i manage. i have the main program built but i want to build MDrun openmp support. I am using the latest version of Intel Parallel Studio XE (2018.3) in order to compile, as well as the latest boost (1.67.0), gsl (2.5) and openmil (3.1.1) sources. Here is my attemt/configuration to build mdrun with openmpi:


---------------------------------

rm -rf *
export CC=icc
export CXX=icpc

export  GROMACS_INSTALL_DIR=/cm/shared/apps/gromacs/2018.2

export CMAKE_PREFIX_PATH=/cm/shared/apps/boost/1.67.0:/cm/shared/apps/gsl/2.5

export CFLAGS="-O3 -fast-transcendentals -ftz -fma -fp-model fast=2 -qopt-calloc  -fp-speculation=fast -fpic -ip -no-prec-div -xHOST -qopenmp"

export CXXFLAGS=$CFLAGS
export LDFLAGS=$CFLAGS

export MPICC=mpiicc

cmake \
-DCMAKE_VERBOSE_MAKEFILE=TRUE \
-DCMAKE_INSTALL_PREFIX=$GROMACS_INSTALL_DIR \
-DGMX_GPU=OFF  -DGMX_MPI=ON -DGMX_OPENMP=OFF \
-DGMX_EXTERNAL_BLAS=OFF \
-DGMX_BUILD_MDRUN_ONLY=ON \
-DGMX_FFT_LIBRARY=fftw3  -DGMX_BUILD_OWN_FFTW=ON  .. && make -j25 mdrun && make  install-mdrun

 --------------------------


It gets 95% of the way through the build and fails with the following:

Can anyone provide any insights as to why this is failing and perhaps give me some pointers to get it to  compile?
