sci-libs/scipy: disable parallel build completely. |
| 9 |
|
| 10 |
After 4 years discussion and debugging, we conclude that Python 3 is |
| 11 |
deeply broken in parallel builds for anything involving compiling of |
| 12 |
C/C++/fortran code. The problem is universal, regardless how |
| 13 |
dev-python/numpy is built. |
| 14 |
|
| 15 |
Numpy and scipy upstream cannot do anything about this. We bite the |
| 16 |
bullet and disable parallel build of scipy completely. |
| 17 |
|
| 18 |
Thanks to all who have contributed to this heroic marathon |
| 19 |
debugging. We regret that only a workaround can be provided at this |
| 20 |
moment. |
