invalid command name "gcc" while executing "gcc rsa.c -o rsa -lm" (file "./run.sh" line 1)

does gcc-4.9.2 works correctly on ns-2.35 or is it gcc-4.4

  • What's the CLI output of which gcc? – earthmeLon Oct 11 '15 at 18:46
  • gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04) this is the version of gcc i'm using.. – Rakend Raj Oct 11 '15 at 18:47
  • Any way we can take a look at the contents of run.sh? – earthmeLon Oct 11 '15 at 18:48
  • gcc rsa.c -o rsa -lm ./rsa ns main.tcl – Rakend Raj Oct 11 '15 at 18:49
  • I'm glad to know your version of gcc, but what's the output of which gcc. What happens when you place which gcc at the top of your script and try to run it. It should have output. – earthmeLon Oct 11 '15 at 18:53
  • invalid command name "gcc" while executing "gcc rsa.c -o rsa -lm" (file "./run.sh" line 1) this is the output of gcc-4.8.4 which i'm using now – Rakend Raj Oct 11 '15 at 18:55
  • gcc-4: /usr/bin/gcc-4.8 /usr/bin/gcc-4.6 /usr/bin/gcc-4.9 /usr/bin/gcc-4.4 /usr/bin/X11/gcc-4.8 /usr/bin/X11/gcc-4.6 /usr/bin/X11/gcc-4.9 /usr/bin/X11/gcc-4.4 these are the versions of gcc in my system and i'm running gcc-4.8 – Rakend Raj Oct 11 '15 at 19:00
  • invalid command name "gcc" while executing "gcc rsa.c -o rsa -lm" (file "./run.sh" line 1) my question is i have installed gcc but why am i getting this error as invalid command...?? – Rakend Raj Oct 11 '15 at 19:02
  • Yeah, but I'm asking you to change your file to look like this: http://pastie.org/private/gustqjww03d5tplyigznmw . I want to see the actual output of these commands, not your interpretation of my question. – earthmeLon Oct 11 '15 at 19:04
  • invalid command name "which" while executing "which gcc" (file "./run.sh" line 1) – Rakend Raj Oct 11 '15 at 19:07
  • So, it looks like your Environmental Variables are messed up. You're missing things, such as $PATH, most likely. Maybe it's as simple as placing #!/bin/bash at the top of your script, but it seems like you have bigger problems than that. What shell is it using? echo $0 should tell you if it's sh or bash or what. – earthmeLon Oct 11 '15 at 19:09
  • yes u r right ... pls help me to set a proper path may be i wish to put gcc-4.4 as default – Rakend Raj Oct 11 '15 at 19:11
  • Have you tried opening a new terminal? That one might have gotten messed up in some way. Can the terminal you're in run any commands? What happens if you run which gcc in the terminal, not in the script? Does it actually give you good output? – earthmeLon Oct 11 '15 at 19:11
  • Your issue is NOT gcc right now. If which won't work, most likely nothing will work. We need to get your shell working by determining which shell you're using and why your Environmental Variables aren't loading. – earthmeLon Oct 11 '15 at 19:12
  • /usr/bin/gcc this is what i am getting on running the command "which gcc" – Rakend Raj Oct 11 '15 at 19:14
  • Okay, so the issue here is that whatever is running your script is not loading up your environmental variables. I'm not really sure the solution. What happens when you add #!/bin/bash to the top of the script? Does that help at all? – earthmeLon Oct 11 '15 at 19:16
  • no i'm gettintg the same thing when i add the above thing.. – Rakend Raj Oct 11 '15 at 19:18

  • Is it bash run.sh vs ./run.sh that's making it work? – earthmeLon Oct 11 '15 at 19:26
  • i really appreciate ur time and dedication ..#earthmeLon thanks again .. – Rakend Raj Oct 11 '15 at 19:27
  • #!/bin/bash echo $0 echo $PATH which gcc gcc rsa.c -o rsa -lm ./rsa ns main.tcl

    i mean bash run.sh

  • "invalid command name" sounds more like a tcl error than a bash one: are you sure you are executing this command in a bash shell? – steeldriver Oct 11 '15 at 20:32

Instead of running the script as ./run.sh, be sure that the first line of the script is #!/bin/bash and run it with bash run.sh.
