[ Background: tr1 is a set of extensions to the C++ Standard Library |
| 2 |
giving various useful things like hash tables and smart pointers. There |
| 3 |
are partial implementations included in g++-4.1 and boost and full |
| 4 |
implementations available from Dinkumware. It is likely that a lot of |
| 5 |
C++ apps will start using it in the not too distant future. ] |

What is the best way to handle packages that require parts of tr1? The |
| 8 |
options appear to be: |
| 9 |
|
| 10 |
* Hard dep upon boost. This sucks for g++-4.1 users. |
| 11 |
|
| 12 |
* Hard dep upon g++-4.1, which isn't available for all archs. This |
| 13 |
doesn't even work because there's no guarantee that >=4.1 is being used |
| 14 |
even if it's installed. |
| 15 |
|
| 16 |
* || ( ) deps, and hope that if the user has 4.1 installed then they're |
| 17 |
using it. Since library implementations aren't runtime switchable, this |
| 18 |
will lead to breakages if users upgrade gcc and then remove boost. |

None of these are particularly nice... |
