Sorry, but you provided way too less information. Especially because Qt is compiled with hidden visibility. See /usr/share/qt/mkspecs/common/g++.conf for example. Whatever you try to compile, most likely that one is broken and not Qt.

I am trying to compile simple kde4 app with cmake. Line with find_package( KDE4 REQUIRED ) causes these errors:

CMake Error at /usr/share/apps/cmake/modules/FindKDE4Internal.cmake:1271 (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-2.8/Modules/FindKDE4.cmake:95 (FIND_PACKAGE)

Lines 1268 and 1272 of my FindKDE4Internal.cmake:

try_compile(_compile_result ${CMAKE_BINARY_DIR} ${_source_file} CMAKE_FLAGS "${_include_dirs}" COMPILE_OUTPUT_VARIABLE _compile_output_var)

if(NOT _compile_result)
message(FATAL_ERROR "Qt compiled without support for -fvisibility=hidden. This will break plugins and linking of some applications. Please fix your Qt installation.")
endif(NOT _compile_result)
