[help]error in simulation and synthesis

i want to do rtl simulation and synthesis.Now i have two questions:

1. does it need c compiler (cc) in sunstudio to compiler the c code ? can gcc do this job?Because when use"sims -group=core1_mini", the error shows that there are no cc or CC package.

2. we use design_compiler ver.2002.05 to compile fpu_add,but it indicate synopsys.vX-2005.09 is the synthesis tool for this chip.so can syn ver2002.05 work well?
