GROMACS version: Anything before 2021
GROMACS modification: No
I’m trying to install GROMACS via CLI on Linux. I’ve noticed that following the install steps, I get the same issue for several different versions at this step:
cmake … -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON
Namely, it cannot download the regression file. If you go to the download page for one of these pre-2021 releases, I noticed that all of the regression test links (1) have a link like this: http://**gerrit.**gromacs.or (can’t put >2 links, so I shortened URL) and (2) if you click on them you get a 403 forbidden error.
On a newer, 2021-and-later GROMACS version, the regression test link is like this:
And clicking the link works (likewise, the CLI install process works as well). Swapping the “gerrit” for “ftp” doesn’t work in the original case.
I know these older versions are no longer supported, but wondering if there is a way to install them still? I need them to run some code that worked on an older version (has the “Group” cutoff-scheme, but the newer ones only accept “Verlet”… but that throws off the program given the other parameters in the *.mdp file).
Also I tried the version in this question ( gromacs.bioexcel.eu/t/unable-to-install-older-version-of-gromacs/4230), and ran into the same issue with the group cutoff-scheme.
