Hi Elliot, Did you look at my online instructions? You can also use a prebuilt distribution as Arjen suggests. If you’re not actually on the mailing list but just sending to it so didn’t see that, he recommended http://www.equation.com/servlet/equation.cmd?fa=fortran . You would still need to make sure your PATH is set so that gfortran and the other binaries you’d need are visible. Unless you are adept with the Windows command line, you should look into a graphical development environment. The problem with those is that most don’t support Fortran well or at all. The two free, cross-platform ones I know that do are Geany and Code::Blocks. Geany is more like a nice editor with some buttons for compiling and running (and it can run a Makefile) whereas Code::Blocks is closer to a traditional IDE. Both may expect you to be using gfortran and would require some configuration if you wanted to use the Intel oneAPI option. Easy to do, but an extra step to keep in mind. VSCode is all the rage but I fought with it just to try to use it for C++ and didn’t want even to try Fortran. > On Apr 25, 2022, at 9:57 PM, Elliot Cramer wrote: > > Windows 10; how can we do this? > Elliot > > On 4/23/2022 10:00 PM, Jerry D wrote: >> Elliot, >> >> Let me know what system you want the compiler to run on? >> >> Linux, Windows, PowerPC? >> >> I can guide you through installing on some of these. >> >> Usually we build it from source.
