git pull
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh

Configure and build OpenBLAS

For native you can use cmake:

cd build
git clone https://github.com/OpenMathLib/OpenBLAS.git
cd OpenBLAS
git checkout v0.3.24
cd build
cmake -DCMAKE_INSTALL_PREFIX=${PWD}/../.. ..

For emscripten use make:

cd build
git clone https://github.com/OpenMathLib/OpenBLAS.git
cd OpenBLAS
git checkout v0.3.24
emmake make install libs shared CC=emcc HOSTCC=gcc TARGET=RISCV64_GENERIC NOFORTRAN=1 C_LAPACK=1 USE_THREAD=0 NO_SHARED=1 PREFIX=${EMSDK}/upstream/emscripten/cache/sysroot
