Although xt-clang is based on clang, for some reason, it still lists xcc system include path as the first search path (e.g. for stddef.h), and the clang system include path as last. This creates a big issue when the code starts to use any standards past C89 (since xcc is based on GCC 4.2). We can use compiler property nostdin_include to add -isystem to compiler options. However, some modules (e.g. picolibcs) somehow ignore this. So we also need to forcibly do add_compile_options() to make sure the clang system include path is placed before the xcc system include path. Signed-off-by: Daniel Leung <daniel.leung@intel.com> |
