qt 4.2.2 install in tru64 cxx

hi
i install qt-x11-opensource-src-4.2.2 in tru64 with cxx
the system condision is
Compaq C++ V6.2-024 for Compaq Tru64 UNIX V5.1B (Rev. 2650)
at first i use ./configure and is list the error did not know the file ansi!!!
an then i see the qmake.conf and find the
QMAKE_CXXFLAGS = -x cxx -model ansi $$QMAKE_CFLAGS
then i view the same file in qt 3.3.2 and there is no -model ansi
so i change like below
QMAKE_CXXFLAGS = -x cxx $$QMAKE_CFLAGS
the configure step was pass
but when in the gmake step it appear the error below

cxx -c -x cxx -g -pthread -DQT_SHARED -DQT_BUILD_CORE_LIB -DQT_NO_CAST_TO_ASCII
-DQT_ASCII_CAST_WARNINGS -DQT3_SUPPORT -DQT_MOC_COMPAT -DGNU_LIBICONV -I../../m

what is this meaning? Is know body know how to intall this verson of qt??
