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.
The only line in sources.list is deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi which I presumed was the stable line. It provides me with a choice of cpp -4.6, -4.7 and -4.8 I would prefer to run with 4.8 as I have it everywhere else.
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.
My next attempt was to simply get the source and compile the package, but apt-get complained about no URI, even after I duped the above line and changed "deb" to "deb-src" like the man page example. Got the bits with a web browser instead and just need to work out how to do the build. I may still need to find and hack the data file on the packages to say the cpp-4.8 provides cpp or whatever debian parlance is.
