Yes, this is possible, and it probably should be done this way. But currently there are a few steps before this can happen. It’s in my todo list. Sorry that I can’t have a better answer at the moment.

As far as I understand, the FORTRAN bindings are auto generated by a python script. Would there be a way to get the result of the configure test for float128 to trigger or not the generation of the real128 and complex128 bindings?

Or is there a preprocessor variables that stores the result of this test?
