GROMACS version: 2019.4  
GROMACS modification: Yes/No

Dear gromacs users,

I have tried to install the gromacs-2019.4 version that I used in another system.  
But when I issue the command below  
`cmake .. -DGMX_BUILD_OWN_FFTW=ON \ -DREGRESSIONTEST_DOWNLOAD=OFF \ -DGMX_GPU=ON \ -DCUDA_TOOLKIT_ROOT_DIR=/apps/cuda/10.0 \ -DGMX_MPI=ON \ -DGMX_SIMD=AVX2_256 \ -DCMAKE_INSTALL_PREFIX=/home01/x2051a02/apps/gromacs-2019.4-plumed-build \ -DREGRESSIONTEST_PATH=/home1/x2051a02/apps/regressiontests-2019.4/`

AND The CMake error occured  
REGRESSIONTEST\_PATH invalid. The path needs to contain gmxtest.pl.

So I used the other option below  
cmake … -DGMX\_BUILD\_OWN\_FFTW=ON \   
-DREGRESSIONTEST\_DOWNLOAD=ON   
-DGMX\_GPU=ON   
-DCUDA\_TOOLKIT\_ROOT\_DIR=/apps/cuda/10.0   
-DGMX\_MPI=ON   
-DGMX\_SIMD=AVX2\_256   
-DCMAKE\_INSTALL\_PREFIX=/home01/x2051a02/apps/gromacs-2019.4-plumed-build

Then I got the erorr message below:

I just checked and the download that is failing for you seems to be working fine for me. This might have multiple issues, but two most likely ones are

- a temporary issue on the server side
- a firewall that does not allow you to download

A quick-fix last resort option is to disable the regressiontests in CMake, though I would not recommend.

Also, have a look at this topic, which is almost identical:

> Hi Chetna, From [http://manual.gromacs.org/documentation/current/install-guide/index.html:](http://manual.gromacs.org/documentation/current/install-guide/index.html:) Alternatively, you can download and unpack the GROMACS regression test suite [http://gerrit.gromacs.org/download/regressiontests-2020.3.tar.gz](http://gerrit.gromacs.org/download/regressiontests-2020.3.tar.gz) tarball yourself and use the advanced cmake option REGRESSIONTEST\_PATH to specify the path to the unpacked tarball, which will then be used for testing Give that a try.
