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.
