Re: [CMake] How to link the output of a custom command (VS2013) when the output is an obj file, since LinkObjects is hardcoded to false?

[Nick Georghiou]

Hi,

 

Thanks for the quick reply. I enabled asm language and it now links. 

 

Apologies for the noob question; 

 

Thanks Nick

Hi,

why don't you just add the asm file to your add_library() call and enable the 
ASM language?

Hi,

 

I have the custom command provided below which successfully creates mydll.obj 
in the correct intermediate directory. However the LinkObjects property of the 
custom command within Visual Studio 2013 is set to false and therefore the 
object file is not linked. Upon inspection of the CMake code, it seems that the 
LinkObjects property is hardcoded to false and there is no cmake option to 
specify otherwise.

 

Is there another way to get the object file to link that I am missing. Any help 
on this would be greatly appreciated.

My custom command:

 

add_custom_command(

OUTPUT "$(IntDir)mydll.obj" 

COMMAND ml64.exe /c /nologo /Fo"$(IntDir)mydll.obj" /Zi "%(FullPath)" 

MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/mydll.asm)

CMake code in file cmVisualStudio10TargetGenerator.cxx:

 

if(this->LocalGenerator->GetVersion()

> cmGlobalVisualStudioGenerator::VS10)

  {

  // VS >= 11 let us turn off linking of custom command outputs.

  this->WritePlatformConfigTag("LinkObjects", i->c_str(), 3);

  (*this->BuildFileStream ) << "false\n";

  }

}
