Kde 4.2: Qt compiled without support for -fvisibility=hidden

I got this error when tried to compile few plasmoids and crystal windeco for kde4.2. What should i do?

This is crystal kwindeco compiling error, plasmoids also complained about no support for -fvisibility=hidden.

Code:

CMake Error at /usr/share/apps/cmake/modules/FindKDE4Internal.cmake:1053 (message):

  Qt compiled without support for -fvisibility=hidden.  This will break

  plugins and linking of some applications.  Please fix your Qt installation.

Call Stack (most recent call first):

  /usr/share/cmake-2.6/Modules/FindKDE4.cmake:81 (FIND_PACKAGE)

  CMakeLists.txt:4 (find_package)

I would suggest re-compiling Qt4 with the --fvisibility=hidden flag.

Thanks, i'll probably try this. I guess it should be easy by modifying qt slackbuild in current.

Oh, it's extremely simple to modify the SlackBuild script! :)

But is there any reason that the official package complied without -fvisibility=hidden support?
