hi Jim
Will it help if i post my jam-root file? Its included below:
import python ;
if ! [ python.configured ]
{
ECHO "notice: no Python configured in user-config.jam" ;
ECHO "notice: will use default configuration" ;
using python ;
}
# Specify the path to the Boost project. If you move this project,
# adjust this path to refer to the Boost root directory.
use-project boost
: "C:/Program Files/boost/boost_1_42" ;
# Set up the project-wide requirements that everything uses the
# boost_python library from the project whose global ID is
# /boost/python.
project
: requirements <library>/boost/python//boost_python ;
# Declare the three extension modules. You can specify multiple
# source files after the colon separated by spaces.
python-extension hello : TestWrap.cpp ;
# A little "rule" (function) to clean up the syntax of declaring tests
# of these extension modules.
local rule run-test ( test-name : sources + )
{
import testing ;
testing.make-test run-pyd : $(sources) : : $(test-name) ;
}
>From what you said, its seems the Test1.cpp file needs to be listed under
the extension modules, is it?
Its as if bjam is totally ignoring Test1.cpp. Any definition/declaration in
Test1.cpp file doesn't work.
