As MW already pointed out, the C++ compiler of your new distribution
possibly generates object code which can't be linked with object code
generated by the C++ compiler of your previous distribution. So, you
should play it safe and rebuild everything your project provides or
links against unless the latter stems from the current distribution.

Foremost, try to rebuild comprehensively using a clean build directory.
