If you notice that platform-specific headers by getarch.exe are not generated correctly, It could be due to a known debug runtime DLL issue for arm64 platforms. config Release Known issue getarch.exe execution error G Ninja -DCMAKE_C_COMPILER=clang -DBUILD_WITHOUT_LAPACK=1 -DNOFORTRAN=1 -DDYNAMIC_ARCH=0 -DTARGET=ARMV8 -DARCH=arm64 -DBINARY=64 -DUSE_OPENMP=0 -DCMAKE_SYSTEM_PROCESSOR=ARM64 -DCMAKE_CROSSCOMPILING=1 -DCMAKE_SYSTEM_NAME=WindowsĬmake -build. Build static library with BLAS routines using CMakeĬlassic flang has compatibility issues with cmake hence only BLAS routines can be compiled with CMakeĬmake.

Ensure that it is accessible in environment variables CPATH, LIBRARYPATH, and LDLIBRARYPATH. However the problem is that it does not find OpenBLAS: BLAS++ requires a BLAS library and none was found. Build OpenBLAS static library with BLAS and LAPACK routines with Makeįollowing command can be used to build OpenBLAS static library with BLAS and LAPACK routines It clones successfully and CMake than lets BLAS++ search for any BLAS implementation. The following steps describe how to build the static library for OpenBLAS with and without LAPACK 1. There is no installer for classic flang and the zip package can be extracted and the path needs to be added to environment PATH. Download and install classic flang for windows on armĬlassic flang is the only available FORTRAN compiler for windows on arm for now and a pre-release build can be found here Run the LLVM installer and ensure that LLVM is added to environment PATH. Thus, to configure and build a CMake based project, you can run the following commands: cmake -G Ninja -DCMAKEBUILDTYPE Release cmake -build.Download and install clang for windows on armįind the latest LLVM build for WoA from LLVM release pageĮ.g: LLVM 12 build for WoA64 can be found here MSYS2 provided CMake defaults to Ninja (but this is not the default in upstream CMake, so its safest to explicitly specify it).
