open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I have been trying to install for the last couple of days telemac but without any luck. Although I have come up with many barriers, i believe i have come to the last one. When I try to compile, there is a gfortran error regarding the location of a file or directory, and the problem is quite clear: the configuration file is not putting backslashes properly. No idea how to solve this, already have tried several changes no luck. Please find attached the error message and the configuration file.
