Hi guys, |
| 21 |
|
| 22 |
I don't like that solution at all. What will happen if you have system wide |
| 23 |
singular and sage-singular? |
| 24 |
If you add this file there is a good chance that someone wanting to use the |
| 25 |
system provided singular will end up using sage-singular. |
| 26 |
|
| 27 |
Just for the purpose of testing for side effects, I installed singular-3.1.1. |
| 28 |
revdep-rebuild didn't pick up on sage-core after that. Probably because |
| 29 |
libsingular lacks an soname and is completely unversioned. |
| 30 |
|
| 31 |
No. sage-env takes care of telling sage where to look. There is no real |
| 32 |
perfect solution so long as we have ship sage-singular. |
| 33 |
For now I would put a file in /etc/revdep-rebuild masking the offending |
| 34 |
libraries. |
| 35 |
50sage-core: |
| 36 |
#Those files look for a version of libsingular that will be located through |
| 37 |
# LD_LIBRARY_PATH at run-time. |
| 38 |
LD_LIBRARY_MASK="lib1.so lib2.so lib3.so" |
| 39 |

Of course that means that revdep-rebuild cannot pick up the fact that |
| 42 |
they are broken. Which of course it may not be able to do anyway because |
| 43 |
of the lack of versioning. |
| 44 |
On the positive side a change in sage-singular will always coincide with |
| 45 |
a change of sage-core so there shouldn't be any trouble. |
