Which Fortran compilers are usable on Raspberry Pi?

#1

Which Fortran compilers are usable on Raspberry Pi, e.g., model 4B?

Here is the information about such a model with the recommended Raspberry Pi OS, which is 32-bit.

gfortran is readily available by a simple sudo apt install gfortran, which is great. Do you know other compilers that are compatible with Raspberry Pi? Thank you very much.

I think ARM has a version of FLANG/CLANG that runs on LInux. Don’t know what it would take to get it to run on a PI (if it does at all). DuckDuckGo is your friend

Thank you @rwmsu . I had a try, but failed. The installer complained something like “incorrect binary file format”. I am not sure whether it is due to the fact that the OS is 32-bit.

What is the operational system put on the memory chip/available to you? From the characteristic red swirl shown top left on the home page of Raspbian/Rasperry Pi OS here tailored to the device, one can assume the OS is an off-spring of Linux Debian. Running synaptics (maybe this requires once a sudo apt-get install synaptics) likely offers you gfortran (.or. gcc). As by today, Debian 12/bookworm (branch testing) reached version 12.2.0-14 (release/package for both).

For a more detailed view per release of the OS, see e.g., the table compiled by distrowatch; it states gcc 10.2.1 is offered for the OS shipped by 2022-09-26.

Thank you @nbehrnd . The OS is the “Raspberry Pi OS, the recommended operating system for most users”. It is based on Debian.

As you said, gfortran is readily available with apt. I hope to know whether there is any other, in case someone here has some experience.

I think there is a 64 bit version of the Raspberry Pi OS but I don’t know if its officially maintained. Installing that instead of the 32 bit version might be an option.
