That allowed it to build, but the llvm backend does not work once installed. I get an error like:

$ lfortran hello.f90
sh: line 1: clang: command not found
The command 'clang -o a.out a.out.tmp.o  -L"/usr/bin/../share/lfortran/lib" -Wl,-rpath,"/usr/bin/../share/lfortran/lib" -llfortran_runtime -lm' failed.

I think it points to something still being misconfigured, either in the PKGBUILD, or lfortran's build system.

The error message from using makepkg is coming from the wasm backend, but I don't believe the clean chroot method built the wasm backend, and hence didn't encounter the error. Is this distribution intended to include the wasm backend? If not, what about my environment is causing it to try and be included?

The message about missing clang is true (it's not installed on my system), but the PKGBUILD doesn't list it as a dependency, and there's not a version available in official repos that would be compatible with the listed requirement of llvm11. So do we really still need to stick to llvm11, or could we just list both llvm and clang?

Not sure what's wrong, It compile fine in a clean chroot. Try to compile it using "extra-x86_64-build" instead of "makepkg" as described here

I still get a build error:

Any help would be appreciated.

Updated to 0.17.0, latest version as per https://lfortran.org/download/

Version 0.18.0 is available now. Any chance this could be updated to it?

Ok, now it should compile fine.

Can't install on two machines.

I can't install it on either an Arco box and an Almost fresh Arch box, In both machines I get the same error when compiling:
