It is possible to extract my current toolchain?

Hi I want to migrate to a modern operating system, but I want to conserve my current (an older) GCC and GLIBC version to be able to obtain the same binary files. I know that it is possible to download and use other toolchains for this, but I can't found my exact combination of GCC and GLIBC versions, so I want to build my toolchain with my desired combination. It is possible?

Solution

  • It is possible?

    Yes: building a cross-compiler that will contain older GCC and target older GLIBC is possible.

    However, it is non-trivial. It is also far from guaranteed to reproduce your existing builds.

    A better approach might be to set up a chrooted environment, or a VM, containing your current toolchain and GLIBC.
