A toolchain to compile Fortran to Webassembly, and a few projects using it.
Blog post: https://chrz.de/2020/04/21/fortran-in-the-browser/
Docker image: https://hub.docker.com/r/stargate01/f90wasm
This project was originally published in 2020. Today, in 2024, the FORTRAN compiler landscape has changed quite a bit – while FORTRAN still does not enjoy first-class WebAssembly support in the LLVM toolchain, it is now possible to set up a much more sane toolchain by applying a few patches to LLVM.
Dr George W Stagg has published an excellent writeup of his LLVM modifications, and the application of the resulting toolchain to several real-world projects. Specifically, the WebR project and a cool BLAS-based in-browser digit classifier.
Run ./f90wasm/build.sh to build the docker image locally. A pre-compiled image is available on the Docker Hub.
Run ./test/test.sh to compile the test application, and host it on http://localhost:8080 . Use ./test/clean.sh to remove compiled test binaries.
