I can't seem to get output from the lfortran jupyter kernel.
I installed via conda install for:
- lfortran
- jupyter
I can run jupyter and select the lfortran kernel. However:
I see no hello world and also no error.
If in a second cell I call new it crashes the kernel.
The global scope in LFortran is special to enable interactivity and usage in a notebook and defines a set of additional rules. You actually don't need a program body to run any Fortran code there, just using the print statement directly will work:
print *, "Hello world!"
The extensions to Fortran available are described here.
Further, a program itself is not supposed to be callable, rather it should execute directly after being declared (this might be a bug in LFortran, reported it in lfortran#648). Instead you might want to declare a subroutine:
subroutine new
print *, "Hello world!"
end subroutine new
And than run it with
call new
