| 4 | Subject: [PATCH 18/47] cpp: honor sysroot. |
| 5 | |
| 6 | Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile |
| 7 | preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location |
| 8 | rather than the --sysroot option specified on the commandline. If access to that directory is |
| 9 | permission denied (unreadable), gcc will error. |
| 10 | |
| 11 | This happens when ccache is in use due to the fact it uses preprocessed source files. |
| 12 | |
| 13 | The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix, |
| 14 | -isystem, -isysroot happen and the correct sysroot is used. |
