Hi Volodya,

Thanks for your help.

I am using OBJ as an output as it is a valid source for a library, and this 
was how I could 'wedge' in the test script execution to the compilation 
dependency model. If I move the .check file to being a dependency requirement 
instead of a source, bjam doesn't call my script. With the current approach I 
am using, the script is being called, but unfortunately does not prevent 
other sources such as the CPP files from being compiled on failure, although 
at least the overall build is marked as a fail, which is still very useful.

Here's the script I am currently using:

<check.jam>
import type ;
type.register CHECK_SCRIPT : check ;
import generators ;
generators.register-standard check.run_script : CHECK_SCRIPT : OBJ ;
actions run_script
{
    echo Running checking script...
    rm -f $(<)
    $SHELL $(>)
    if test $? -eq 0 ; then
        touch $(<)
        exit 0
    else
        exit 1
    fi
}
</check.jam>

<Jamfile>
import check ;

lib mylib
    : # sources
    [ glob *.cpp ]
    $(LIB)/build/mytest.check
    ;
</Jamfile>

Many thanks again,
