Install two gcc in parallel

[mmehrwald]

Hi,

I try to install two versions of gcc in parallel. The version 4.4 is already installed in Fedora 12 but due to some problems with boost I need also 4.1. I tried to compile this version but I always got the following compiler error:

WARNING: `makeinfo' is missing on your system.  You should only need it if
         you modified a `.texi' or `.texinfo' file, or any other file
         indirectly affecting the aspect of the manual.  The spurious
         call might also be the consequence of using a buggy `make' (AIX,
         DU, IRIX).  You might want to install the `Texinfo' package or
         the `GNU make' package.  Grab either from any GNU archive site.

I tried 4.1.1 and 4.1.2 and got the same error in both versions. makeinfo is also installed and configure found it but I still get the warning about it.

Does anyone know how to install two versions of gcc or how to overcome this error?

Thanks,
Markus
