From 33a7a55d39c040ba09af2d69f7fa9cf8e6f84c91 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 29 Mar 2013 09:22:00 +0400 Subject: [PATCH] cpp: honor sysroot. Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location rather than the --sysroot option specified on the commandline. If access to that directory is permission denied (unreadable), gcc will error. This happens when ccache is in use due to the fact it uses preprocessed source files. The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix, -isystem, -isysroot happen and the correct sysroot is used.
