源码编译 openblas for windows on arm

参考 https://github.com/OpenMathLib/OpenBLAS/wiki/How-to-build-OpenBLAS-for-Windows-on-ARM64

环境

os: win11
cpu: arm64

llvm 编译器

https://github.com/llvm/llvm-project/releases/
我下载的是 LLVM 18.1.8 ： https://github.com/llvm/llvm-project/releases/download/llvmorg-18.1.8/LLVM-18.1.8-woa64.exe

运行LLVM-18.1.8-woa64.exe安装到路径 C:\workspace\tools\LLVM

flang

https://github.com/kaadam/flang/releases

我下载这个压缩包 v0.3 版本： https://github.com/kaadam/flang/releases/download/v0.3/flang_woa_2021_11_30.zip

解压到路径 C:\workspace\tools\flang_woa

编译

配置环境变量
在openblas源码目录下
打开powershell ，输入：

$env:Path += ";C:\workspace\tools\LLVM\bin;C:\workspace\tools\flang_woa\bin"

cmake 编译

# 创建构建目录
mkdir build
cd build# 配置 CMake
cmake .. `-G "Ninja" `-DCMAKE_INSTALL_PREFIX=C:\workspace\program\openblas `-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=Windows# 构建 OpenBLAS
cmake --build . --config Release# 安装 OpenBLAS
cmake --build . --target install --config Release
