Even after setting the path using setenv, I cant seem to run cl.exe or other exe's in the "path" As can be seen below, when I run "which nmake" it says, no nmake but if I do ls $PATH/nmake.exe, it lists correctly c:/Users/kck $ which nmake.exe which: no nmake.exe in (c:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC\\bin) c:/Users/kck $ ls $PATH/nmake.exe c:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin/nmake.exe c:/Users/kck $ Regards, Kashyap
