LFortran Compiles PRIMA: LFortran can now compile and execute libprima/PRIMA, marking the eighth production-grade third-party code. PRIMA is a Fortran package for solving general nonlinear optimization problems without derivatives.

• Compilation Steps: Set up the environment with conda create -n lfortran lfortran=0.46.0 make cmake and git clone https://github.com/Pranavchiku/prima.git. Then, set environment variables for macos or linux and run git clean -dfx, FC="lfortran --cpp" cmake -S. -B build -DCMAKE_INSTALL_PREFIX=$(pwd)/install && cmake --build build --target install to build and compile. For optimizations, use FC="lfortran --cpp --fast".
• Benchmarks: Compared LFortran with GFortran without optimizations on a MacBook Air M2. Compiling cobyla took 5.284s with LFortran and 6.881s with GFortran. In examples, LFortran was sometimes slower and sometimes faster than GFortran.
