From 8ee2d3f718c79dc7c2e5e859766e23e8058cf3a6 Mon Sep 17 00:00:00 2001 From: Justin Kilpatrick Date: Sat, 25 Nov 2017 16:14:59 -0500 Subject: build: accept gcc/g++ without minor version Build dependency: Please install the GNU C Compiler (gcc) 4.8 or later cc -dumpversion | grep -E '(4\.[8-9]|5\.[0-9]|6\.[0-9]|7\.[0-9])' Build dependency: Please install the GNU C++ Compiler (g++) 4.8 or later g++ -dumpversion | grep -E '(4\.[8-9]|5\.[0-9]|6\.[0-9]|7\.[0-9])' Prerequisite check failed. Use FORCE=1 to override. On my Fedora 26 machine gcc and g++ -dumpversion returns a whole number '7' failing the regex introduced in commit: b78de6207f6fc1a9db857942cb89f9fcf730a240 This change makes minor versions optional in the build dependency regex for gcc and g++ whenever any minor version would be accepted and the whole number version is sufficient as a dependency check. For versions 4.* a minor version is still required.
