Hello, Today I installed an snapshot of Qt 5.4.0 for Linux x86 on my Kubuntu 14.04 and found a problem: it links to libudev.so.0, while Ubuntu 14.04 provides libudev.so.1.
I was wondering if it would be a good idea for Qt to move from explicit linking to dlopen/dlsym. That would help supporting different versions of a certain library, and support different codepaths at runtime depending on which one was found. Eg. libudev.so.0 or libudev.so.1, libstreamer-0.10.so or libgstreamer-1.0.so, etc Incidentally, MESA is doing that for udev already: http://lists.freedesktop.org/archives/mesa-dev/2014-January/052548.html And the proprietary database Intersystems Caché has been doing that for decades to ease the burden of support for many different platforms (these guys supported VMS until not too long!). They do this for EVERY third party dependency: libssh2, Xalan, Xerces-C, libodbc, Cenera (Samba), ICU, etc Yes, code is a bit more complex, but support for newer and older platforms is also easier because there is no need to recompile. Also, some customers do not want "custom" versions of third-party libraries but only the "official" one. -- Pau Garcia i Quiles http://www.elpauer.org (Due to my workload, I may need 10 days to answer)
