On a Pi I got sick of having 3 versions of cpp so I just asked synaptic to remove the lot and then installed just 4.8. This worked fine except I found that I needed to make symbolic links from cpp to cpp-4.8 etc.
I haven't bothered to check, but these are probably provided by the "cpp" package rather than the "cpp-4.N" package. The latter is versioned such that e.g. cpp=4:4.7.2-1 Depends on cpp-4.7.
I now need to install libtool but synaptic wants to also install cpp (-4.6) without an option.
I see that libtool depends on cpp, so tell your package manager to install the version of cpp that you want, not the version that is in your target release. e.g. bash4$ rmadison -aamd64 cpp debian: cpp | 4:4.4.5-1 | squeeze | amd64 cpp | 4:4.7.2-1 | wheezy | amd64 cpp | 4:4.9.1-5 | jessie | amd64 cpp | 4:4.9.2-1 | sid | amd64 new: So, apt-get install libtool cpp/jessie # or apt-get install libtool cpp=4:4.9.1-5 Presumably you're on raspbian, where this may not be an option. PS: mixing stable and testing is likely to break things. I recommend you use the default cpp that your release ships, and stop pining for newer versions.
I figured I could tell apt-get to forget about cpp and just get on with it (ie --nodeps in rpm), but it doesn't seem to have such an option.
apt corresponds to yum, not rpm. dpkg has corresponding --force-* commands. If you use them, you WILL blow your foot off.
