Dependency problems with the g++ package

[Peppe <scaricoapalla@fastwebnet.it>]

Hi =)
this is my problem:

Enterprise:~# apt-get install g++
[cut]
Sorry, but the following packages have unmet dependencies:
  g++: Depends: g++-3.2 (>= 1:3.2.2-0pre2) but it is not going to be installed
E: Sorry, broken packages
Enterprise:~# 


ok.... so let's see what's wrong:

Enterprise:~# apt-get install g++-3.2
[cut]
Sorry, but the following packages have unmet dependencies:
  g++-3.2: Depends: libstdc++5-dev (>= 1:3.2.2-0pre7) but it is not going to be installed
E: Sorry, broken packages
Enterprise:~# 

Enterprise:~# apt-get install libstdc++5-dev
[cut]
Sorry, but the following packages have unmet dependencies:
  libstdc++5-dev: Depends: libc12-dev but it is not installable
E: Sorry, broken packages
Enterprise:~# 

Enterprise:~# apt-get install libc12-dev
Reading Package Lists... Done
Building Dependency Tree... Done
Package libc12-dev has no available version, but exists in the database.
This typically means that the package was mentioned in a dependency and
never uploaded, has been obsoleted or is not available with the contents
of sources.list
E: Package libc12-dev has no installation candidate
Enterprise:~# 

I couldn't find libc12-dev deb packages via web.

Do I have to forget g++?
Thanks a lot, bye
