Hi,

Many thanks for your response.

# CMAKE\_LINKER was

CMAKE\_LINKER:FILEPATH= **/usr/bin/ld**

# Then I have changed it to, as you suggested (though here is no ld file)

CMAKE\_LINKER:FILEPATH= **/home/khademul/bin/gcc11/bin/ld**  
//ADVANCED property for variable: CMAKE\_LINKER  
CMAKE\_LINKER-ADVANCED:INTERNAL=1

# However the problem persists and remains the same.

cmake .. -DGMX\_BUILD\_OWN\_FFTW=ON -DREGRESSIONTEST\_DOWNLOAD=ON -DMPI\_C\_COMPILER=mpicc -DGMX\_MPI=on -DCMAKE\_INSTALL\_PREFIX=/home/khademul/bin/gromacs -DCMAKE\_C\_COMPILER=/home/khademul/bin/gcc11/bin/gcc -DCMAKE\_CXX\_COMPILER=/home/khademul/bin/gcc11/bin/g++ **-DCMAKE\_LINKER** =/home/khademul/bin/gcc11/bin/ld

## I do not have root permission and CMAKE, GCC etc installed locally. (default things are tool old version)

module load openmpi-1.8-x86\_64  
module load tools/openBLAS-0.2.18  
module load lib/OpenBLAS-0.3.9  
module load compilers/python-3.6.2-gcc

# cmake version 3.20.0-rc4

# gcc version 11.2.0

thanks, # any more suggestions?
