Kernel compilation - 2.6, x86_64, CentOS4.1 - Discuss

6 Nov 2005


      Hi
I am having trouble compiling some 2.6 kernels on a x86_64 box under
CentOS4.1.  I cannot use xconfig at all and menuconfig on my system is
unreadable.  It appears to be something to do with the Qt library but I
have all the necessary bits installed:
qt-devel-3.3.3-9.3
qt-3.3.3-9.3
but note that the second of these only is installed both for x86 and
x86_64 - the first is installed for x86_64 only.
I have tried both the standard kernel 2.6.9-11.EL-smp-x86_64 and also
2.6.11.12 and the same problem exists.  Googling around, it appears to be
to do with a makefile in scripts/kconfig and none of the fixes work.
On issuing make xconfig, the messages always end up:
HOSTLD  scripts/kconfig/qconf
/usr/bin/ld: cannot find -lqt
collect2: ld returned 1 exit status
make[1]: *** [scripts/kconfig/qconf] Error 1
make: *** [xconfig] Error 2
and the fixes suggest removing the middle two lines in
scripts/kconfig/Makefile (starting at line 130 for the 2.6.11.12 case):
LIBPATH=$$DIR/lib; LIB=qt; \
-	$(HOSTCXX) -print-multi-os-directory > /dev/null 2>&1 && \
-	  LIBPATH=$$DIR/lib/$$($(HOSTCXX) -print-multi-os-directory); \
    if [ -f $$LIBPATH/libqt-mt.so ]; then LIB=qt-mt; fi; \
But that still returns the same fault.
Can anyone advise?  The same kernel compiles perfectly on an x86 box.
TIA
John
