verilogams simulation

Hello all
I am trying to learn how to run verilog AMS simulations in cadence. We
have IC5141 and IUS810. I need to learn and give a demo to other
students. I found a tutorial which walk you through simulating the
Analog Equalizer given in the sample VFS_PHY_180 library provided by
cadence. It is based on the Cadence Verilog AMS simulation guide.
However I get the following error. I also get the same error running a
simple ideal ADC example. I have all systemc folders in path and it
shows GCC 3.2.3 and GCC 4.1 install. Do I need to some how install GCC
3.3 inside cadence directory. Please help.

I'm not sure what's the exactly reason for this, just share my experience.

suppose you have 2 lib files with the same name, say, libgcc.so.1, one is provided by linux system distribution, the other is provided by EDA tool you installed. So the path for them are:
/lib/libgcc.so.1
/edatool/lib/libgcc.so.1

normally, the former one is much newer than the latter one, and the EDA tool is only supported by the latter one.

in LD_LIBRARY_PATH, you must put the latter path in front of the former one, so that the EDA tool can load the correct file.
