Just to make sure, I just performed a stage 1 install in a separate dir. I |
| 14 |
found it did select the new 3.4 compiler. It indeed did not uninstall the old |
| 15 |
compiler, BUT told you to run "emerge -e system" Requiring the whole of |
| 16 |
system to be recompiled. That means everything, including the 3.3 compiler |
| 17 |
according to pretend. Indeed that means you'll end up with a 3.3 compiler |
| 18 |
besides a 3.4 one instead of having a 3.3 libstdc++. If that bothers you, |
| 19 |
just uninstall the 3.3 compiler and be done. It is the crippled compiler that |
| 20 |
doesn't support c++ anyway, ensuring that nothing has been built against 3.3 |
| 21 |
libstdc++ yet. |

The crippled gcc will be replaced by the "emerge -e system" that bootstrap.sh |
| 32 |
tells you to perform. As such the system is not broken that much, but |
| 33 |
bootstrap.sh might indeed be "fixed" to special case this situation more. It |
| 34 |
would however require a rebuild of gcc. The reason being that this rebuild |
| 35 |
specifies a dependency on libstdc++3 which then would not be longer provided. |
| 36 |
Binary packages might however assume it's existence (from source will use the |
| 37 |
3.4 libstdc++). |
| 38 |
|
| 39 |
The "way around this" would be to change bootstrap.sh back to building a |
| 40 |
minimal version of the current version that is then used to compile the rest |
| 41 |
of the system, including the C library and gcc itself. Between this however |
| 42 |
the original bootstrap compiler could be removed. |
| 43 |
|
| 44 |
This however goes deep into bootstrapping a linux system. A complicated matter |
| 45 |
that is not for the weak of heart. |
