Issues about cmake ..

[WangYun1995]

Hi aamaricci,

The information returned after that I input cmake .. is shown below

 CMake Deprecation Warning at CMakeLists.txt:4 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Does it mean that the installation fail?

Hi, this is error message from Cmake which, in order, - informs you that you're using a too old version of Cmake and - informs you that MPI can not be found in your system. By default SciFortran uses MPI, so if you do *not* want to use it you should set the cmake variable USE_MPI=False. This is done using the option -D: $cmake .. -DUSE_MPI=False this will analyze your system without checking for MPI. If everything goes well a suitable Makefile is created and you can compile/install the library as usual: $make $make install $make post-install Cheers. A

But my cmake version is the latest release , i.e. "CMake 3.19.1".

[aamaricci]

Check that the version you are using is actually the one you are invoking $cmake --version
Anyway this is only a warning, the error message comes from missing MPI.

[WangYun1995]

Actually, I checked the version by invoking cmake --version.

So I didn't understand why this warning appears.

[aamaricci]

I see. I guess you can safely ignore this warning and compile without MPI support. Everything should be fine. Cheers. A
