SuiteSparse网址：DrTimothyAldenDavis/SuiteSparse: The official SuiteSparse library: a suite of sparse matrix algorithms authored or co-authored by Tim Davis, Texas A&M University. (github.com)

主要编译命令：

    mkdir -p build && cd build     cmake ..     cmake --build .     sudo cmake --install .    

一、arm64架构不匹配

错误信息：

-macosx_version_min has been renamed to -macos_version_min ld: warning: ignoring duplicate libraries: ‘-lgcc’, ‘-lgcc_s.1.1’ ld: warning: ignoring file ‘/Desktop/SuiteSparse-dev/build/AMD/CMakeFiles/AMD.dir/Source/amd_1.c.o’: found architecture ‘arm64’, required architecture ‘x86_64’

解决：

cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 .. 

二、CholMOD编译问题

Desktop/SuiteSparse-dev/SuiteSparse_config/SuiteSparse_config.h:684:6: error: expected ‘)’ void SUITESPARSE_BLAS_DGEMV( Desktop/SuiteSparse-dev/SuiteSparse_config/SuiteSparse_config.h:593:37: note: expanded from macro ‘SUITESPARSE_BLAS_DGEMV’ #define SUITESPARSE_BLAS_DGEMV SUITESPARSE_BLAS ( dgemv , DGEMV )

CholMOD编译有问题，解决方案参考：Issues · DrTimothyAldenDavis/SuiteSparse (github.com)

具体操作，在CmakeLists.txt中添加：

# 添加 BLAS_UNDERSCORE 定义到 C 编译器标志 set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -DBLAS_UNDERSCORE")  # 添加 BLAS_UNDERSCORE 定义到 C++ 编译器标志 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DBLAS_UNDERSCORE") 

三、gmp和mpfr架构不匹配

ld: warning: ignoring file ‘/opt/homebrew/Cellar/mpfr/4.2.1/lib/libmpfr.6.dylib’: found architecture ‘arm64’, required architecture ‘x86_64’

ld: warning: ignoring file ‘/opt/homebrew/Cellar/gmp/6.3.0/lib/libgmp.10.dylib’: found architecture ‘arm64’, required architecture ‘x86_64’

需要重新下载x86_64架构的包，那么需要重新下载inter架构的intel，下载命令如下：

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"  

需要先确保新的 Homebrew 路径在你的 PATH 中。编辑 ~/.zshrc 并添加：

export PATH="/usr/local/bin:$PATH" 

这个路径保证brew首先用/usr/local下的针对intel的brew包，然后再用下面的命令下载x86的包：

arch -x86_64 brew install mpfr gmp 

Note:

• 完成上面步骤后，需要删掉build重新构建SuiteSparse

• 记得添加路径：

  export CPPFLAGS="-I/usr/local/opt/gmp/include $CPPFLAGS" export LDFLAGS="-L/usr/local/opt/gmp/lib $LDFLAGS"
