I'll try and see if I can compile a gcc 4.9.3 chain on the CentOS 5 machine (I need C++11).

The docker container looks interesting but I haven't used it yet: does it need some specific install on the target machine? I don't have any install rights on the Cento 5.11 machine....

Thanks,


Michele

If you're using a newer Ubuntu environment, I'd suggest using a CentOS 5 docker container. Either that or the VM.

    Hi Michele,

    This could become a painful exercise. You basically have two options:
    1) Treat it as a cross-compilation project, or
    2) Create a virtual machine running CentOS 5.8 and do the build there.
    If I were you, I would go for the second option.

    Cheers,
    Marcel.
