An error appears at "qt-everywhere-opensource-src-4.8.1" compilation:

Also, my system file /usr/include/unicode/umachine.h belongs to dev-libs/icu-4.8.1.1-r1 package.

Comment 1 Lamarque V. Souza 2012-10-12 13:23:45 PDT 
The installed libxml2 was compiled with icu support on. You can either recompile libxml2 without icu or enable icu support in qt-webkit:

# cd qt-everywhere-opensource-src-4.8.1
# sed -i -e '/CONFIG\s*+=\s*text_breaking_with_icu/ s:^#\s*::' \
	src/3rdparty/webkit/Source/JavaScriptCore/JavaScriptCore.pri
# ./configure -icu && make && make install

Thanks! It works.
Comment 3 Allan Sandfeld Jensen 2013-09-10 02:44:03 PDT 
libxml2 and Qt4 needs to either both be build with libicu or without.
