Dear All: I got the executable nam by the following steps: ./configure --enable-gcc --with-tcl --with-tk --with-otcl --with-tclcl make and run it as follows: nam ex/test.nam or nam -S ex/test.nam But nothing showed up on the screen. I can see it running. I tried all the nam traces and downloaded sample traces but failed. Any help is appreciated. Thanks, Dapeng
