Seems some odd cmake borkage is going on trying to build kdesdk-4.8.90
(4.8.80 suffered the same, but I hadn't noticed then), in that any
modules using kde4_add_plugin seem to not get compiled with -fPIC
properly, and fail linking, for example,
dolphin-plugins:
/usr/bin/ld:
CMakeFiles/fileviewsvnplugin.dir/fileviewsvnplugin_automoc.o: relocation
R_X86_64_32 against `_ZN17FileViewSvnPlugin16staticMetaObjectE' can not
be used when making a shared object; recompile with -fPIC
...
blindly replacing kdesdk toplevel CMakeLists.txt with that from 4.8.4 makes
things happy again.
So, more data:
... = a bunch of -I... includes not relevant,
4.8.4 gets compiled as:
cd .../kdesdk-4.8.4/build/dolphin-plugins/svn && /usr/lib64/ccache/c++
-DMAKE_FILEVIEWSVNPLUGIN_LIB -D_BSD_SOURCE -D_XOPEN_SOURCE=500
-D_BSD_SOURCE -DQT_NO_STL -DQT_NO_CAST_TO_ASCII -D_REENTRANT
-DKDE_DEPRECATED_WARNINGS -DKDE4_CMAKE_TOPLEVEL_DIR_LENGTH=48
-DQT_USE_FAST_CONCATENATION -DQT_USE_FAST_OPERATOR_PLUS

-Woverloaded-virtual -fno-threadsafe-statics -fvisibility=hidden
-Werror=return-type -fvisibility-inlines-hidden -O2 -g -DNDEBUG
-DQT_NO_DEBUG -fPIC ... -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -o
CMakeFiles/fileviewsvnplugin.dir/fileviewsvnplugin_automoc.o -c
/home/rdieter1/pkgs.fedoraproject.org/kdesdk/foo/kdesdk-4.8.4/build/dolphin-plugins/svn/fileviewsvnplugin_automoc.cpp
and in 4.8.90 this get's compiled with:
cd .../kdesdk-4.8.90/build/dolphin-plugins/svn && /usr/lib64/ccache/c++
-DMAKE_FILEVIEWSVNPLUGIN_LIB -DQT_NO_STL -DQT_NO_CAST_TO_ASCII
-D_REENTRANT -DKDE_DEPRECATED_WARNINGS
-DKDE4_CMAKE_TOPLEVEL_DIR_LENGTH=48 -DQT_USE_FAST_CONCATENATION
-DQT_USE_FAST_OPERATOR_PLUS -O2 -g -DQT_NO_DEBUG ...
-D_LARGEFILE64_SOURCE -o
CMakeFiles/fileviewsvnplugin.dir/fileviewsvnplugin_automoc.o -c
/home/rdieter1/pkgs.fedoraproject.org/kdesdk/foo/kdesdk-4.8.90/build/dolphin-plugins/svn/fileviewsvnplugin_automoc.cpp
many differences (mostly flags being removed), but most noticeable
causing the immediate issue was -fPIC
any advice, clues, suggestions?
Fedora 17 (and f18/rawhide) here, using cmake-2.8.8-4.fc17
