Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Dear all,

A naive grep tells me the IAR compiler detection sets CMAKE_CXX_LINK_FLAGS
in its compiler detection.

If I use `CMAKE_CXX_LINK_FLAGS`, I have to pass the option manually, which is 
not convenient. I was looking for something more automatic:

  1.  I set `cxx_std_14` in `target_compile_feature` of my `CMakeLists.txt`;
  2.  Then `CMAKE_CXX14_STANDARD_COMPILE_OPTION` is added to the compiler flags 
(which is the case);
  3.  Then `CMAKE_CXX14_STANDARD_LINK_OPTION` (or 
`CMAKE_CXX14_STANDARD_COMPILE_OPTION` by default) is added to the linker flags.

I cannot find in the documentation if such a thing is possible. Is it?

Best regards,

Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Hello all,

So, I managed to configure my `Fujitsu-CXX.cmake` file to use the Fujitsu C++ 
compiler with MPI as well. The problem of not detecting headers of the STL 
(like `array`) was due to the fact the C++ standard flag was not set correctly.

I am facing another problem though: the linker needs the C++ standard flag to 
be set, which is not something GCC needs. I could not find a way to make 
`CMAKE_CXX**_STANDARD_COMPILE_OPTION` applied to the linker as well. What I am 
missing?

Best regards,

Robert,

so that all users could benefit from the improved compiler detection :)
That is my plan! If I can make a compiler module which works well enough, I 
will submit it as a merge request.

Regarding the detection of MPI with FindMPI, I failed to detect the MPI 
compiler using `MPI_CXX_COMPILER_FLAGS`. But using the normal Fujitsu compiler 
binary (not the wrapper) and setting `MPI_CXX_COMPILER`, I can detect it.

The problem is now that it does not detect the STL anymore at compiling time: 
"error: namespace "std" has no member "array"" (note that I used to build the 
project with a hand made Makefile, so the source code is valid). I checked the 
`include` directory of the compiler and it contains the Array header, though. 
In other warnings, I clearly see that this `include` directory is used. What is 
wrong here?

Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Thank you for your answer.

This means I have to override 
`/usr/share/cmake/Modules/Compiler/Fujitsu-DetermineCompiler.cmake`? This is 
not unfeasible, but it may seems tricky to my users. Since detecting compiler 
version is not a crucial task, maybe I will keep this file as it and 
concentrate on other ones.

Another question I have is regarding MPI. The `find_package(MPI REQUIRED)` 
directive fails with "Could NOT find MPI (missing: MPI_CXX_FOUND)". I have no 
clue on how to help the detection of MPI. The compiler I give to CMake is 
actually an MPI wrapper that only needs one argument to enable MPI features. I 
tried with some exotic-named GCC compilers at my lab (which are MPI wrappers as 
well) and it could detect MPI with no problem. Where should I start?

Best regards,

I believe the only way is to have your version of

CMake. When it comes to known compilers CMake explicitly includes the
version it ships.

Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Robert,

Thank you for the advice.

As I want to take account of compiler version, I overrided the 
`Fujitsu-DetermineCompiler.cmake` file by copy-pasting and editing it in the 
folder of `CMAKE_MODULE_PATH`. However, the installation 
`Fujitsu-DetermineCompiler.cmake` file is always used instead. What should I do?

Best regards,

For an initial implementation I would base the work on the PGI
compiler module (
https://gitlab.kitware.com/cmake/cmake/blob/v3.14.3/Modules/Compiler/PGI-CXX.cmake
) not the GNU-CXX module.
This will allow you to add a new compiler with only meta-language
flags ( cxx_std_11, cxx_std_14, ... ) and you avoid the complexity of
having to manually build the feature tables.

Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Kai,


Thanks for your answer and for your presentation. So, I will try to add support 
for this Fujitsu compiler. Is there a list of the common compile features that 
I can base me upon? I plan use `GNU-CXX.cmake` as a source of inspiration.


If I succeed to complete the `Fujitsu-CXX.cmake` file, I will propose it as a 
merge request.

If you want to add support to your specific compiler, you could add or extend 
another Fujitsu-DetermineCompiler.cmake
file and append your CMAKE_MODULE_PATH in order to CMake to find it. You 
probably also need to adjust
*Fujitsu-CXX.cmake, Fujitsu-CXX-FeatureTests.cmake and so on.

I gave a talk a few years ago that shortly explains the whole process of CMake 
initialization and compiler verification which
you can find here:

Hello Cmake community,

I would like to use Cmake to build research simulation programs in a Fujitsu 
supercomputer environment. Unfortunately, it seems that Cmake (version 3.14) 
does not support any compile feature for the Fujitsu C++ compiler (FCCpx, 
version 2.0.0 P-id: T01815-02 (Jul 12 2018 13:13:18)). I add I am pretty new to 
Cmake. Searching for similar issues, I found only this 
[thread](https://cmake.org/pipermail/cmake-developers/2014-August/010989.html), 
which talk about basic support of the compiler.

I tested it on a simple project, and the line:

```cmake
target_compile_features(test PUBLIC cxx_std_11)
```

fails with this message:

```
CMake Error at CMakeLists.txt:15 (target_compile_features):
  target_compile_features no known features for CXX compiler

  "Fujitsu"

  version .

```

So, it seems that the compiler is detected (without its version), but compile 
features are not known. To be sure, I ran this simple test to list any 
supported features:

```cmake
cmake_minimum_required(VERSION 3.1.0 FATAL_ERROR)
project(foobar CXX)
message("Your C++ compiler supports these C++ features:")
foreach(i ${CMAKE_CXX_COMPILE_FEATURES})
message("${i}")
endforeach()
```

and no feature are listed.

So, what should I do from now on? Are there some people here using Cmake with 
Fujitsu who could help me? Should I propose a patch with the different compile 
features of the compiler? Or should I address it to Fujitsu?

Thanks for your help,

Re: [CMake] Support of compile features for Fujitsu C++ Compiler

[Kai Wolf]

If you want to add support to your specific compiler, you could add or extend 
another Fujitsu-DetermineCompiler.cmake
file and append your CMAKE_MODULE_PATH in order to CMake to find it. You 
probably also need to adjust
*Fujitsu-CXX.cmake, Fujitsu-CXX-FeatureTests.cmake and so on.

I gave a talk a few years ago that shortly explains the whole process of CMake 
initialization and compiler verification which
you can find here:

Greetings,

[CMake] Support of compile features for Fujitsu C++ Compiler

[Zehner Paul]

Hello Cmake community,

I would like to use Cmake to build research simulation programs in a Fujitsu 
supercomputer environment. Unfortunately, it seems that Cmake (version 3.14) 
does not support any compile feature for the Fujitsu C++ compiler (FCCpx, 
version 2.0.0 P-id: T01815-02 (Jul 12 2018 13:13:18)). I add I am pretty new to 
Cmake. Searching for similar issues, I found only this 
[thread](https://cmake.org/pipermail/cmake-developers/2014-August/010989.html), 
which talk about basic support of the compiler.

I tested it on a simple project, and the line:

```cmake
target_compile_features(test PUBLIC cxx_std_11)
```

fails with this message:

```
CMake Error at CMakeLists.txt:15 (target_compile_features):
  target_compile_features no known features for CXX compiler

  "Fujitsu"

  version .

```

So, it seems that the compiler is detected (without its version), but compile 
features are not known. To be sure, I ran this simple test to list any 
supported features:

```cmake
cmake_minimum_required(VERSION 3.1.0 FATAL_ERROR)
project(foobar CXX)
message("Your C++ compiler supports these C++ features:")
foreach(i ${CMAKE_CXX_COMPILE_FEATURES})
message("${i}")
endforeach()
```

and no feature are listed.

So, what should I do from now on? Are there some people here using Cmake with 
Fujitsu who could help me? Should I propose a patch with the different compile 
features of the compiler? Or should I address it to Fujitsu?

Thanks for your help,
