Different dependencies for xcb plugin 5.6.0 and 5.6.1-1 (built from sources)
-
We have Qt 5.6.0 manually built on Debian 7 from sources where xcb plugin has the following dependencies
tester@TEST-EPSILON:~/platforms$ ldd libqxcb.so
linux-vdso.so.1 => (0x00007fffd6e56000)
libQt5XcbQpa_x64.so.5 => not found

libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f7e55c0f000)"not found" for Qt libs is not an error, question is not about this.
Now we build from Qt 5.6.1-1 sources and have 4 times more dependencies for xcb plugin.

librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f02e9a45000)What is the reason? How it could be? We build with -qt-xcb parameter both version.
So now our application can not run on some Unix systems because of dependencies. If they are all needed, how could it work before? -
Hi, perhaps it has to do which rpaths are written in the .so files, if you try
readelf -d libqxcb.soon your libqxcb.so files, are there any differences? -

...I think I remove not so useful info.
Main question is about libudev.so.0 and libts-0.0.so.0. What is the reason xcb depends on them?
