Re: [Boost-build] Using Boost.Build with Boost.Python: Three Questions; "Copy" Rule

Hi Jurko,

Many thanks for your help. This answers almost all of my questions. I have one problem though.

I need to copy test_hello.py (a Python test harness for the Python extension "hello") to each variant of the build directory:

(project root)\build\msvc-8.0\debug\link-static\threading-multi\
(project root)\build\msvc-8.0\release\link-static\threading-multi\

How can I achieve this using the builtin install rule? I've tried a number of things, but a copy of the file doesn't appear.

Many thanks once again!

Best wishes,
Paul

   You can specify it either for your project target (see
http://www.boost.org/doc/tools/build/doc/html/bbv2/advanced/projects.html)
as in:

     project my-project : build-dir C:\Haleluya

or you can specify it using the --build-dir command line option (see http://www.boost.org/doc/tools/build/doc/html/bbv2/advanced/invocation.html).

   Depends what your 'hello' target does. Did you try running 'bjam hello variant=debug' and 'bjam hello variant=release'? Did that create the DLL files you need? If it did not then the install target got no such DLL targets as sources...

   I believe that the install rule (a.k.a. stage) you are using is exactly what you need. :-)

   Hope this helps.

   Best regards,
     Jurko Gospodnetiæ
