I am experimenting using boost.build to build a Qt4 application. The version of boost.build is V2 M12, and Qt4 version 4.4.1.  The compiler is VS2005 on Windows.  

The Qt4 is not enabled in the global user-config.jam file.

In jamroot file,

import qt4 ;

if ! [ qt4.initialized ]

{

    ECHO "Use QT4 from the custom path" ;

    using qt4 : c:/qt4 ;

}

On my computer, the Qt4 lib filenames do not have version suffix “4”, So I modified one line in Qt4. The project compiled just fine.

However, I would like to use qt4 from a path relative to the current source directory. Our convention is to place third party libs in a directory relative to the current source location, such as ../../lib/qt4.

If I changed the Qt4 path to relative path, the project failed to compile:

if ! [ qt4.initialized ]

{

    ECHO "Use QT4 from the custom path" ;

    using qt4 : ../../lib/qt4 ;

}

It looks that qt4.jam module does not handle relative path. Is there a patch or workaround?
