From 60b24f43959d1a99962cda42075a4f16966becb2 Mon Sep 17 00:00:00 2001 From: "Matteo M. Fusi" Date: Tue, 19 Jun 2018 17:28:15 +0200 Subject: SConstruct: additional message for the error checking of the python 2.7 headers One of the most common errors during the installation of gem5 is the one related to the failure of the check of the Python2.7 headers in the SConstruct file. In some cases the headers are correctly installed, but a wrong selection of the C compiler can make this check fail. This commit wants to add some useful information this error message.
