Description Eilif Muller 2006-09-16 04:51:05 UTC
It seems the dev-libs/boost-1.33.1 does not properly install files necessary to build boost.python modules.

For example:

in BOOST_SRC/libs/python/example/

one must edit Jamrules so that:
path-global BOOST_ROOT : /usr/include ;

one must edit boost-build.jam so that:

boost-build /usr/share/boost-build/v1 ;

Then running 
$ bjam test1 
... the build succeeds, but the module does not import because it is not linked to libboost_python.so

The reason for this is can be seen in the report of two missing files:
/usr/include/Jamrules: No such file or directory
/usr/include/libs/python/build/Jamfile: No such file or directory

These two files are in BOOST_SRC/

thus the /usr/includes/boost is insufficent to build boost.python modules.
Additional files need to be installed, perhaps to a new dir such as /usr/share/boost-root.  If then also the include files where put there under /usr/share/boost-root/boost, then 
one must edit Jamrules so that:
path-global BOOST_ROOT : /usr/share/boost-root ;

This should fix the problem.
Comment 1 David 2006-09-29 08:30:28 UTC
I too am having this problem but do not fully understand your fix.  The sentence:

"Additional files need to be installed"

./libs/python/build/Jamfile is included in the boost tarball, but not currently installed by the ebuild.  I agree that it could be put somewhere like /usr/share/boost-root.  However, which file is it looking for when it attempts to access /usr/include/Jamrules?  The Jamrules for the current project?  The Jamrules in the root of the boost tarball?  Or something completely different?

"If then also the include files where put there under"

I would assume this could be symlinked.

Ok. Let's see if I understood the problem correctly:

You're trying to compile the python-examples in the boost-package, right?
Because there are actually ebuilds in portage, which use boost.python and they work without adding files.

As far as I can see, the examples are meant to be built using boost as it is in the tarball. So, please try to set BOOST_ROOT to BOOST_SRC and see if it works.
. boost-build can point to /usr/share/boost-build/v1, that should be ok.

Closing this bug since I really don't think it's a problem we could/should/have to fix (see comments above). If you don't agree, please reopen or contact me.
