[cmake-developers] CMAKE :: mingw make files with response file for includes

[Jayakumar, Lenindarbi]

Hello,

I have encountered a problem with response file usage for includes.
My project is using tasking compiler.

Issue:
Response file link flag "CMAKE_C_RESPONSE_FILE_LINK_FLAG" is not customizable for include paths.
Cmake generated the *.rsp file always using @ but this is not accepted by tasking compiler. Tasking compiler expects -f instead of @.

...
C_INCLUDES = @CMakeFiles/dummyTarget/includes_C.rsp

This issue is only with includes response file. For objects, CMAKE_C_RESPONSE_FILE_LINK_FLAG works.

Project setup:
set(CMAKE_C_RESPONSE_FILE_LINK_FLAG "-f ")
set(CMAKE_C_USE_RESPONSE_FILE_FOR_OBJECTS 1)
set(CMAKE_C_USE_RESPONSE_FILE_FOR_INCLUDES 1)

Possible cause:

The @ symbol is hardcoded in "cmMakefileTargetGenerator::AddIncludeFlags" function in file https://gitlab.kitware.com/cmake/cmake/blob/master/Source/cmMakefileTargetGenerator.cxx.

  if (useResponseFile) {
    std::string name = "includes_";
    name += lang;
    name += ".rsp";
    std::string arg = "@" +
      this->CreateResponseFile(name.c_str(), includeFlags,
                               this->FlagFileDepends[lang]);
    this->LocalGenerator->AppendFlags(flags, arg);
  }

However, the implementation should be like in "cmMakefileTargetGenerator::CreateObjectLists" function.

    // Lookup the response file reference flag.
    std::string responseFlagVar = "CMAKE_";
    responseFlagVar +=
      this->GeneratorTarget->GetLinkerLanguage(this->ConfigName);
    responseFlagVar += "_RESPONSE_FILE_LINK_FLAG";
    const char* responseFlag = this->Makefile->GetDefinition(responseFlagVar);
    if (!responseFlag) {
      responseFlag = "@";
    }
