| 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. |
