In general it's problematic to build on a newer version, and then expect it to run on an older old ... It's also not guaranteed the other way round, but it's way more likely to work :) So yeah, if you want your app to run on CentOS 6.4 you might consider also building on it. > If you used -qt-xcb, then the libqxcb.so plugin will not link to libxcb.so.1. > Therefore, it does not matter what libxcb version you have on the target > machine. That's actually not true: What -qt-xcb does is statically compiling in a lot of the xcb helper libs, namely libxcb-fixes, libxcb-randr, libxcb-shm, libxcb-sync, libxcb-image, libxcb-keysyms, libxcb-icccm, libxcb-renderutil, libxcb-xkb. We can't link libxcb itself statically IIRC because libX11 will pull the system libxcb in anyway ... [1] Yeah, it's sort of a misnomer, but back then I couldn't find a better name, either.
