Hi, |
2 |
|
3 |
After searching the web without much success, maybe somebody in here can |
4 |
direct me into the right direction: |
5 |
I have a software that is providing swig bindings to (among other |
6 |
languages) python, and I'd like to have an ebuild for that and get |
7 |
binding for python2 and python3 at the same time. Building the thing works |
8 |
fine for python2 and python3 on the commandline, but I cannot get my |
9 |
ebuild to build for both python2 and python3 versions. It will build for |
10 |
whatever is set as default python interpreter, but will not find the |
11 |
libraries for the other one. |
12 |
|
13 |
This is what the ebuild reports (with python3 being default): |

This is what I get on the commandline when building: |

The ebuild itself is quite straight-forward (I think), just using |
60 |
cmake-utils to pass on USE flags to options (ENABLE_SWIG_PYTHON2 and |
61 |
ENABLE_SWIG_PYTHON3 in this case). This part works as far as I can see. Is |
62 |
there anything else to consider? Somehow the ebuild environment appears to |
63 |
be different from what I have on the commandline so that the second python |
64 |
version isn't properly found. |
