[Boost-build] Need help in using qt4 in relative path

Subject: [Boost-build] Need help in using qt4 in relative path

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?
