We definitely need to do LAPACK, but we haven’t decided yet if we’ll do some other code first. Right now we are spending some time just fixing bugs that users reported (thank you all!).
Yes, we might be close to get LAPACK working ( based on experience with SciPy, no promises yet ) but need to check thoroughly. We have made efforts in that direction, please find it at Compile Lapack · Issue #1232 · lfortran/lfortran · GitHub. At present, we are analysing what all features are prominently used across codes which we are yet to support, and fixing the reported bugs
