When debugging a C++ program on target using libcstdc++, gdb does not find the pretty printer python support, this is because the init file is installed into /usr/lib which is excluded from gdb's default list of directories to load config's from, where as defaults to load from datadir is still on, it therefore does not load this file warning: File "/usr/lib/libstdc++.so.6.0.33-gdb.py" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load". This leaves the libstdc++ pretty-printers disabled even though added via IMAGE_INSTALL += "gcc-runtime-dbg" Add missing runtime dependency on datetime python module for the pretty printer to work/load successfully. Once the pretty-printer gdb file is moved out of libdir, it may become empty therefore delete it if its empty.
