GROMACS version:2020.2  
GROMACS modification: No  
Hello, everyone  
I’ve been trying to install GROMACS 2020.2 but in the make command I’ve encountered these errors which I don’t really understand since I don’t have much knowledge in make and compilations. The commands I’ve done after making the build directory were:

cmake … -DGMX\_BUILD\_OWN\_FFTW=ON -DREGRESSIONTEST\_DOWNLOAD=ON  
make

The make process stops at the very end. These are the messages I get:  
[0%] Built target fftwBuild  
[0%] Built target scanner  
[3%] Built target thread\_mpi  
[4%] Built target tng\_io\_obj  
[6%] Built target tng\_io\_zlib

[23%] Built target linearalgebra

make[1]: \*\*\* [share/template/CMakeFiles/template.dir/all] Error 2

make: \*\*\* [all] Error 2

Can anyone help me with some insights of what might be causing this error and what could be done to solve it?

Hi, I had similar link problems but solved it by defining some options explicitly.

cmake … -DGMX\_BUILD\_OWN\_FFTW=ON -DREGRESSIONTEST\_DOWNLOAD=ON -DBUILD\_SHARED\_LIBS=ON -DGMX\_PREFER\_STATIC\_LIBS=OFF -DGMX\_FFT\_LIBRARY=fftw3 -DCMAKE\_CXX\_COMPILER=/usr/local/bin/g++ -DCMAKE\_C\_COMPILER=/usr/local/bin/gcc  
make

Hope it helps.

Hi, I used the cmake like you suggested, but I still get the same error.  
Any clues on the solution?  
Thanks for any help you can provide.
