From edf7c18d79b195001d7ed7d05ac30a4d7a64bce1 Mon Sep 17 00:00:00 2001 From: Mikko Koppanen Date: Fri, 19 Nov 2010 09:10:26 +0100 Subject: Add a check that the compiler actually works. The patch tests that the C and C++ compilers actually exist and work. autoconf seems to default to 'g++' when C++ compiler is not found, which causes the following error (when the compiler isn't there): checking for uuid_generate in -luuid... no configure: error: cannot link with -luuid, install uuid-dev. The config.log contains the real error message "g++ command not found" but the error message shown to the user is misleading.
