this is a change in GCC 4.7's c++11 mode (see
http://gcc.gnu.org/wiki/Cxx11AbiCompatibility). There is no "easy"
solution. c++0x/c++11 mode is still marked experimental in GCC, so
better don't use it in production code. so either:
- build qapt in c++98 mode
- rebuilding libapt-pkg in c++11 mode isn't a solution, because it will break
binaries,
which are built in c++98 mode.
- build libapt-pkg both in c++98 and c++11 mode with a different soname. This
approach
doesn't scale for the whole distribution.
- avoid the ABI incompatibility by changing libapt-pkg's ABI, so that it works
with both
c++98 and c++11 mode ().
The last one may be an option until you find the next incompatibility,
so in the long term it might be better to just build in c++98 mode.
** Changed in: gcc-4.7 (Ubuntu)
