Object File Collision Detection Part II: Visual Studio C++ modules about premake-core

[larioteo]

Hello again,

Today, I found a relatively easy fix with an custom override, but certain conditions must be met for it to work. I've set objdir globally under the solution (workspace) with this value "%{wks.location}/Cache/%{prj.name}/%{cfg.buildcfg}". So I don't need to set it per project anyway.

Than, I tried to set Output Files under Project Properties and realized that they are stored separately under the global ClCompile.

It looks like this in the project file:

Notice that Premake updates these properties in the project file:

So it seems that the settings don't interfere, which is nice.

It also looks like that Premake with this new approach doesn't generate the numbered object files, which is also a nice side effect.

require("vstudio")
premake.override(premake.vstudio.vc2010.elements, "clCompile", function(base, prj)
    local m = premake.vstudio.vc2010
    local calls = base(prj)

    if premake.project.iscpp(prj) then
		table.insertafter(calls, premake.xmlDeclaration,  function()

			premake.w('<ModuleOutputFile>$(IntDir)\\%%(RelativeDir)</ModuleOutputFile>')
			premake.w('<ObjectFileName>$(IntDir)\\%%(RelativeDir)</ObjectFileName>')
		end)
    end

    return calls
end)
