replace the compiler in boost build v2

Question

I would like to hook a compiler tool in the boost build.

Note that I do not want to replace the compiler, that is easy:

using msvc : : : <compiler>mycompiler ;

What I am looking for is my tool to be literally placed in front of the execution line. Something similar to the unit-test launcher option.

using msvc : : : <compiler-launcher>launcher ;

to result in

launcher <the original line here>

Ideas how I can do that hopefully without need to change the existing code.

Answer 1

I think this there is currently no support for this, so you are stuck with the <compiler> option. I can think of two possible ways to accomplish this:

1. Try setting the compiler to <compiler>"launcher cl" or

2. Create a batch file which would create the appropriate command line and then use it as a <compiler>cl_wrapper.bat

   That batch file could look something like this:

   cl_wrapper.bat

   @launcher cl.exe %*
