I am open to proposals to do this better. Make conflicting
libstdc++5 and libstdc++5-3.3 packages is not suitable, as with the
first package dependent on libstdc++5-3.3 you are forced to install
this version anyway.
that will happen when gcc-3.3 becomes the default compiler.
It will happen earlier than that. Anything linked with the
libstdc++5-3.3 (even through using the 3.2 headers) will get
dependencies to libstdc++5-3.3.
meantime gcc-3.2 is the default so i don't think there are any
packages out there that depend on the (hypothetical) libstdc++5-3.3.
Any package that is built from now on will have such a dependency.
It is not hypothetical, since libstdc++5-3.3 exists today.
gcc-3.3 the default compiler and keep everything in sync (the
development headers and the library that is) since it looks like you
really want to use gcc-3.3 anyway.
That wouldn't achieve the desired testing. For gcc 3.3, it must be
tested that both the compiler and the library is completely binary
compatible between 3.2 and 3.3. If Debian is not testing that, nobody
There is any reason to believe that they are indeed compatible, and
various procedures have been used to establish that trust, including
regression test suites in gcc itself. However, none of these tests can
replace testing the compatibility "in the wild". These test must happen
before gcc 3.3 is released, so that potential incompatibilities can be
corrected before the compiler goes into production use.
Now, if Debian would use gcc 3.3 as the system compiler, the efficiency
of the testing would be reduced: everything would be compiled with gcc
3.3 after a while, and potential incompatibilities would be hidden by
the fact that the compiler and its library are probably more compatible
within a version than across versions.
