No CMake_Fortran_COMPILER could be found.

Hi,
I was following the SHARPy Installation Guide and on step 4 of the quick installation, where I had to prepare UVLM and xbeam for compilation using gfortran and g++, I ran the “cmake ..” command and ran into this error (attached). I am currently running a macOS Big Sur Version 11.2.3. I’ve tried downloading a Fortran compiler, but I keep encountering the same issue.
Thank you for your help in advance!

Hello,

I might be wrong on this but let's try a few things. I assume you have gfortran installed. If you run on the shell which gfortran what do you get?

The issue that CMAKE is showing is that it cannot find the compiler, you can manually specify where to look for it by running:
FC=/path/to/gfortran CXX=path/to/gcc cmake ..

Give this a go see if it works. If not we'll try and figure something out

Here's what I get.

Then I'm afraid your gfortran installation is broken. You probably need to cleanup and reinstall it. Try again once that's done by deleting the build folder, creating it again and running the FC=/usr/local/bin/gfortran CXX=/usr/bin/g++ cmake .. command.

Ok, thank you, that worked!
Now, where do I get the SHARPy variables?

You are not looking for the correct directory. When you do source <path> that path is relative. In your case you are in the build directory hence you need to go up a directory to find bin (source ../bin/sharpy_vars.sh). Using the TAB key to autocomplete the available options at each level is always helpful
