What does it mean when the configuration for ns WORKS OK, ( including finding tclsh8.0 ) , but the compilation does NOT work and the following message appears : rm -f gen/version.c tclsh8.0 bin/string2c.tcl version_string < VERSION > gen/version.c sh: tclsh8.0: not found *** Error code 1 make: Fatal error: Command failed for target 'gen/version.c' Thanks , raed
