cmake - 通过 `add_subdirectory`添加的库遇到 “No rule to make target while compiling..”错误

Question

我正在尝试清理legacy C-FORTRAN FLOSS code，并且遇到了一个非常奇怪的错误。通过top add_subdirectory file中的CMakeLists.txt添加了一些库/文件夹。在cmake ..文件夹中运行build命令会成功生成MakeFile(除了some minor warnings可能为假阳性)。但是，当使用make进行编译时，出现了一个奇怪的错误:

Scanning dependencies of target umfpack
mingw32-make[2]: Leaving directory '/path/to/elmerfem/build'
mingw32-make[2]: Entering directory '/path/to/elmerfem/build'
[ 46%] Building C object umfpack/src/umfpack/CMakeFiles/umfpack.dir/umfpack_timer.c.o
mingw32-make[2]: *** No rule to make target '/mingw64/include/cblas.h', needed by 'umfpack/src/umfpack/CMakeFiles/umfpack.dir/umfpack_tictoc.c.o'.  Stop.
mingw32-make[2]: Leaving directory '/path/to/elmerfem/build'
mingw32-make[1]: *** [CMakeFiles/Makefile2:265: umfpack/src/umfpack/CMakeFiles/umfpack.dir/all] Error 2
mingw32-make[1]: Leaving directory '/path/to/elmerfem/build'
mingw32-make: *** [Makefile:163: all] Error 2

which I don't know how to debug. In this case the /mingw64/include/cblas.h exists, and the prior CMake outputs:

-- Looking for Fortran sgemm
-- Looking for Fortran sgemm - found
-- Found BLAS: /mingw64/lib/libopenblas.dll.a
-- Looking for Fortran cheev
-- Looking for Fortran cheev - found
-- A library with LAPACK API found.
-- ------------------------------------------------
--   BLAS library:   /mingw64/lib/libopenblas.dll.a
--   LAPACK library: /mingw64/lib/libopenblas.dll.a

Show that BLAS and LAPACK have been successfully found.

I would appreciate it if you could help me know what is the problem and how I can fix it. Thanks for your kind support in advance.

The environment is:

• MSYS2: MSYS_NT-10.0-18363
• Windows Version 1909
• cmake version 3.15.5
• GNU Make 4.3
• gcc.exe (Rev1, Built by MSYS2 project) 9.3.0

P.S.1. I just tested the code on macOS and it compiled with no problem. So it seems to be a Windows/MSYS2 specific problem.

P.S.2. I was told that I should install suitesparse library so I did

 pacman -S mingw64/mingw-w64-x86_64-suitesparse

它没有帮助。

P.S.3。 在this Tweet之后，我还应阐明我正在使用MSYS2的CMake和GNU Make软件包，如here和here所述。

Answer 1

运行mingw64.exe(不是msys2.exe)。

确保安装以下软件包:mingw-w64-x86_64-cmakemingw-w64-x86_64-makemingw-w64-x86_64-suitesparse和C/C++，Fortran编译器。

注意:所有已安装的软件包必须在mingw64目录中。

更改CMakeLists.txt中的WITH_MPI值:

SET(WITH_MPI FALSE ...

查找cmake的路径并使用以下命令进行制作:$ where cmake.exe和$ where mingw32-make.exe
为了简单起见，请使用alias命令:

alias my_cmake=/d/msys64/mingw64/bin/cmake.exe
alias my_make=/d/msys64/mingw64/bin/mingw32-make.exe

在elmer存储库中创建构建目录，然后:

my_cmake -G "MinGW Makefiles" ..

my_make
