I took another approach, following the instructions on this page:
http://kate-editor.org/2014/12/22/qt-5-4-on-red-hat-enterprise-5/
This involves a small patch to the Qt sources, which seems to eliminate
the issue with the kernel headers.
This build is successful, but does not include Webkit.
I think that Webkit is not included because the test for icu fails:
g++ -L /usr/local/lib -L /usr/local/lib/icu -I /usr/local/include/unicode/
-I /usr/local/include/layout/
./qtwebkit/Tools/qmake/config.tests/icu/icu.cpp
/tmp/ccq3GOLd.o: In function `main':
icu.cpp:(.text+0x33): undefined reference to `ucol_open_4_2'
icu.cpp:(.text+0x5d): undefined reference to `ucol_close_4_2'
collect2: error: ld returned 1 exit status
I have installed (from source) icu 4.2.1 and these symbols appear in the
libraries:
strings /usr/local/lib/libicui18n.so.42.1 | grep "ucol_close_4_2"
ucol_close_4_2
The files appear to be the correct format:
file /usr/local/lib/libicui18n.so.42.1
/usr/local/lib/libicui18n.so.42.1: ELF 64-bit LSB shared object, AMD
x86-64, version 1 (SYSV), not stripped
