Using different C-compilers in parallel
I have to mention: I don't like working with C++. I know very well, it is one "mother" of all object oriented programming languages (despite there are others, like LISP). Also their exist very good toolchains and frameworks for C++ like QT (> 4). And it has it's place in a lot of big and serious software products, kernel development, ... but: I think it will be overcome with time due to a lot of facts - especially when it comes developing user applications. The arguments I wrote down in my bachelor thesis many years ago ...
If you have to deal with C++ in Ubuntu there are some caveats. One of them is to use different C/C++-Compiler versions in parallel within one Ubuntu distribution.

A solution is pointed out here:
This boils down to (thanks muru)
