I have tried every possible combination of specifying pre-post build actions in my premake script for a csharp project (targetted at mono), doing just simple things like:

      configuration "Debug"
                defines { "DEBUG" }
                flags { "Symbols","Unsafe" }
                targetdir "bin/debug"
                prebuildcommands
                {
                "echo 'here!'"
 
                }
                 postbuildcommands { "echo 'here!'" }

and, right out of the documentation:

configuration "not windows"
   prebuildcommands { "echo 'here!'" }

But nothing I can do will get the actions added to tho csproj:

  <!-- To modify your build process, add your task inside one of the targets below and uncomment it.
       Other similar extension points exist, see Microsoft.Common.targets.
  <Target Name="BeforeBuild">
  </Target>
  <Target Name="AfterBuild">
  </Target>
  -->

I am using premake 4.3

Am I doing something wrong here?

I am working with a c# project that needs depends on C++ libs for unmanaged calls.
When I specify a c++ project as a "link", the xbuild action for mono simply ignores it:

/media/storage/development/repos/local/Toolkit/Toolkit.sln: warning : Ignoring vcproj 'ToolCore'.
(ToolCore is the c++ project, Toolkit is the C# project).

Right now, it looks like I am just going to have to make a script that will tell compile all of my c++, then call premake on the c#. It would be really nice if I could just run the c# build, and have it build the c++ as a prebuild action... but this doesn't seem to be supported...

Is this a bug, or intentional?

If chaining build actions worked as documented, then I could simply make a build action that would call the premake script for the c++ project, and then call the premake action for the c# project (see my previous post on the help forum).
