Building dev-util/boost-build on a profile with SYMLINK_LIB=no and with USE=python will fail with:

In file included from command.c:17:0:
jam.h:42:20: fatal error: Python.h: No such file or directory
compilation terminated.
In file included from compile.c:13:0:
jam.h:42:20: fatal error: Python.h: No such file or directory
compilation terminated.
In file included from debug.c:7:0:
jam.h:42:20: fatal error: Python.h: No such file or directory
compilation terminated.
In file included from function.c:7:0:
lists.h:51:20: fatal error: Python.h: No such file or directory
compilation terminated.
...

and more messages like this.

The reason seems to be that the build.jam script looks for python under /usr/lib only, but on a SYMLINK_LIB=no profile there may be no python2.7 under /usr/lib (it is under /usr/lib64 instead). The attached patch fixes the problem.

This bug is similar to bug#503624, bug#503746, bug#503064.

Works fine. Minor issues:
- you forgot to inherit multilib.eclass;
- ${EROOT} variable always contains trailing '/'.

Updated the patch as suggested above. It was good to know about ${EROOT}'s trailing slash (the ebuild currently has the trailing slash by the way). Haven't tested it, though.

I see eutils (inherited) already includes multilib, but it is probably better to be explicit if using get_libdir.

This patch may have to also be applied to the other versions - 1.53.0, 1.54.0, 1.55.0.

Hello,

Excuse, I am not sure what about I will say, it's just a suggestion, but what about pkg-config?

Example: pkg-config --cflags --libs python-2.7

Ouput: -I/usr/include/python2.7 -lpython2.7

The problem is the differences between the char of the USE flags python2_7 and python-2.7, which the last is required by pkg-config ; therefore, I can't be a better help to solve this correctly.

Best regards.

Should be fixed in bug #496446
