Assuming every Linux having C and C++ compilers "ready to run" as 
default is wrong. One must nowadays
install them :(  Of course they are free but not installed as default. 
It is assumed that the majority of the
users will never need them.

Very simple tests like :
    $ gcc -v
and
   $ g++ -v
would tell if one may have anything installed.

But these rows also tell what the situation is : No C and C++ compilers 
installed
In the x86_64 installations it is also common to leave the 32-bit 
support away
although the 64-bit target support is provided in C and C++

Building GCC from its sources of course requires fully working C/C++ 
compiler
tools...

You must install the C and C++ compiler parts from the Mageia install 
packages.
How this happens is your homework. I myself read about this Linux distro 
the first time...
People seem to have had problems with this same issue - no compilers 
installed :
