Problem in compitling using RH9

Dear all,
    I am using RH9 to develop my application on Zaurus, but when i tried
to compile the example project, many errors resulted. I knew some
people also having these problems when using RH9 and i have followed
some of the instructions from some of the websites, such as:

install the following packets:
compat-gcc-c++-7.3-2.96.110
compat-libstdc++-7.3-2.96.110
compat-libstdc++-devel-7.3-2.96.110
compat-gcc-7.3-2.96.110

I found them in my RH9 CD1 and installed all. and also, i downloaded the
Qtopia SDK 1.7.0 version which is the latest one, the RH9 default tmake
version is 1.11 which is also the latest one. But either i use tmake or
qmake , compile errors also exist(many unreference errors), how to solve
this problem ? many thanks! and it is urgent for me. thanks again.
