--- Comment #1 from jhyang at andrew dot cmu.edu --- I successfully installed abinit-7.10.2 in Cygwin. When making the file however, I receive a 'fatal error' message and a request to submit a full fug report. Here is the error (similar to what was reported by pascu...@me.com): Fatal Error: Can't open module file '/cygdrive/c/users/Julia/Downloads/abinit-7.10.2/src/mods/m_linalg_interfaces.mod0' for writing at (1): No such file or directory Thank you for your time and help.
