<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have encountered a problem with response file usage for includes.<o:p></o:p></p>
<p class="MsoNormal">My project is using tasking compiler.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>Issue:<o:p></o:p></b></p>
<p class="MsoNormal">Response file link flag “CMAKE_C_RESPONSE_FILE_LINK_FLAG” is not customizable for include paths.<o:p></o:p></p>
<p class="MsoNormal">Cmake generated the *.rsp file always using @ but this is not accepted by tasking compiler. Tasking compiler expects -f instead of @.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">…<o:p></o:p></p>
<p class="MsoNormal">C_INCLUDES = <b><span style="color:red">@</span></b>CMakeFiles/dummyTarget/includes_C.rsp<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This issue is only with includes response file. For objects, CMAKE_C_RESPONSE_FILE_LINK_FLAG works.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>Project setup:<o:p></o:p></b></p>
<p class="MsoNormal">set(CMAKE_C_RESPONSE_FILE_LINK_FLAG "-f ")<o:p></o:p></p>

<p class="MsoNormal">set(CMAKE_C_USE_RESPONSE_FILE_FOR_INCLUDES 1)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>Possible cause:<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The @ symbol is hardcoded in “cmMakefileTargetGenerator::AddIncludeFlags” function in file https://gitlab.kitware.com/cmake/cmake/blob/master/Source/cmMakefileTargetGenerator.cxx.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> if (useResponseFile) {<o:p></o:p></p>
<p class="MsoNormal"> std::string name = "includes_";<o:p></o:p></p>
<p class="MsoNormal"> name += lang;<o:p></o:p></p>
<p class="MsoNormal"> name += ".rsp";<o:p></o:p></p>
<p class="MsoNormal"> std::string arg = "@" +<o:p></o:p></p>
<p class="MsoNormal"> this->CreateResponseFile(name.c_str(), includeFlags,<o:p></o:p></p>

<p class="MsoNormal"> this->LocalGenerator->AppendFlags(flags, arg);<o:p></o:p></p>
<p class="MsoNormal"> }<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, the implementation should be like in “cmMakefileTargetGenerator::CreateObjectLists” function.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Lookup the response file reference flag.<o:p></o:p></p>
