Lei,
Apologies for the delay in reply, I was travelling last week.

This error indicates that there was a problem linking the TraceFlex
simulator (simulators/TraceFlex/libflexus_TraceFlex_v9_iface_gcc.so).
The symbol you mention above is defined in components/Common. I am not
certain why the linker is failing to pick up this component.
First, try the following:
make all-clobber
make TraceFlex
This will completely rebuild TraceFlex from scratch, to ensure that you
are not getting the link error because of a broken build.
If the error persists, then there is some incompatibility between Flexus
and your Linux distribution. The problem would likely disappear if you
can upgrade to Fedora Core 4 or Fedora Core 5. We might be able to narrow
the problem down with some more info (command lines to get the answers
follow each question):
What Linux distribution are you using?
cat /etc/*-release
What version of the binutils package is installed?
rpm -q binutils
What version of GNU make are you using (we require 3.79.1 or newer)?
make -v
