Hu ShuWei,
Look in our standard makefiles for the compiler options.
In the case of Linux with egcs, the Root libraries have been
compiled with the options
-fno-rtti -fno-exceptions
Root can be compiled without specifying these options. However,
we have experienced a huge increase in the size of the object files
when these options are active.
The fact that you see a lot unsatisfied references like TCanvas type_info
node indicates that you have compiled with the default rtti options.
Simply use the standard Root compiler options and you should be able to
run.
