<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Like discussed in the thread "Crashes with libQtUiTools.a if linked multiple times into the same process (with Bsymbolic-functions flag)" on kde-core-devel ( http://lists.kde.org/?t=136829863100001&r=1&w=2 ) symbols from QtUitools.a are not hidden by default in Qt4 and thus will be added to the public symbols of the module/shared lib they are linked to. And thus can appear multiple times in the same process, resulting in symbol clashes and leading to problems at least with the Bsymbolic-functions flag or when being possibly incompatible versions.
Attached patch sees to solve that problem, by adding a macro KDE4_HIDE_SYMBOLS_FROM_STATIC_LIBS which should add any needed linker flags depending on the platform/linker used.
Only issue is that instead of some variable I had to use "QtUiTools.a" as I found no variable which would resolve to that. E.g. ${QT_QTUITOOLS_LIBRARY} resolves to "Qt4::QtUiTools" for me. Any idea what to use there, in case another platform needs another name/prefix here?
Patch is against 4.10 branch, so I hope to get this in 4.10.4
http://lxr.kde.org/search?v=4.10-branch&filestring=&string=QT_QTUITOOLS_LIBRARY shows that there are some more places where the symbols need hiding, but I first want feedback on the proposed approach.</pre>
