hi, while installing the ns-allinone-2.1b6 on red hat 6.2 i am getting a tcl make error. the error message says ERANGE undeclared in generic/tclCompExpr.c . when i checked the file it says that this was a hack to use the file in environments other than unix. can anyone please let me know whether they encountered such problems before and what is the solution.. thanks Renjish.
