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
dnf list --all gcc shows only version
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?
