Error in installing gromac-5.1.4

[cblau]

Hi jishrat,

I’m sorry, I missed to make one connection - with GROMACS2020 we had some trouble installing on cygwin, see the forum post here:

Installation error after make: strcmp instead of strdup?

Hi jyang, That is a specific cygwin issue that you are experiencing - for security reasons, cygwin dumped the strdup function from <string.h>. I reported this as a bug to be fixed in a later gromacs version here Until then you can either: use WSL (Windows subsystem for Linux) instead of cygwin in tmpi_init.cpp you can try replacing in lines 476 and 478 with threads[i].argv[j] = strndup( (*argv)[j] , 1000); (note the extra n in there) This I did not try, because I don’t have cygwin inst…

If that as an option for you, I would recommend to try using the windows subsystem for linux. I know it’s another thing to install and keep track of, but in my experience, it perfroms superior to cygwin and will pay of quickly.
