I'm trying to build CORE Network Emulator from source and I seem to have hit a gcc7 bug, so I want to install gcc 6.4.1 but when I try to run dnf install gcc-6.4.1 I get the error No package gcc-6.4.1 available

Running dnf list --all gcc shows only version 7.1.1-3

I downloaded gcc-6.4.1-1.fc25.x86_64.rpm from https://rpmfind.net/linux/rpm2html/se... but when I tried to run dnf install ./gcc-6.4.1-1.fc25.x86_64.rpm I got an error:

Problem: conflicting requests

    nothing provides cpp = 6.4.1-1.fc25 needed by gcc-6.4.1-1.fc25.x86_64

How can I install gcc-6.4.1?

You need the corresponding version of the cpp package as a dependency.

  • But I would need to install each dependency separately? Can't I just find the dnf package from the previous version somewhere so that it will install all of the dependencies for me as dnf install usually does? – isapir Aug 17 '17 at 14:29
  • There doesn't appear to be dependency reconciliation in this instance – Benny Aug 18 '17 at 2:30
