It seems the toolchain built in the SDK does not give warnings when using system-paths, as it used to do in wrl6. E.g. if using -L/usr/lib when linking. Examples: WRL6: $ i686-wrs-linux-gnu-gcc --sysroot xxxx -o x x.c $ $ i686-wrs-linux-gnu-gcc --sysroot xxxx -L/usr/lib -o x x.c ...../i686-wrs-linux-gnu/bin/ld: warning: library search path "/usr/lib" is unsafe for cross-compilation $ i686-wrs-linux-gnu-gcc --sysroot xxxxx -L/usr/lib -Wpoison-system-directories -o x x.c ...../i686-wrs-linux-gnu/bin/ld: warning: library search path "/usr/lib" is unsafe for cross-compilation $ i686-wrs-linux-gnu-gcc --sysroot xxxxx -L/usr/lib -Wno-poison-system-directories -o x x.c $ WRL8: $ i586-wrs-linux-gcc --sysroot=xxxx -o x x.c $ i586-wrs-linux-gcc --sysroot=xxxx -L/usr/lib -o x x.c $ i586-wrs-linux-gcc --sysroot=xxxx -L/usr/lib -Wpoison-system-directories -o x x.c $ i586-wrs-linux-gcc --sysroot=xxxx -L/usr/lib -Wno-poison-system-directories -o x x.c Looking at the flags used for building the toolchain, it looks like the "--enable-poison-system-directories" option _is_ enabled, but seems the warnings are not produced when wanted. This warning is very useful to guard against mistakes in the build-systems.
Apply attached patch to layers/oe-core before generating SDK.
