I'm trying to run VMD on my raspberry pi system and it installs fine but when I try to run it I get the following error:
/usr/local/lib/vmd/vmd_LINUXCARMA: Command not found.
I've gone through all the other threads about errors with VMD on Ubuntu and the rlwrap error but none of those fixes are working for me. Please help.
When you get the error “Command not found,” it means that Linux or UNIX searched for command everywhere it knew to look and could not find a program by that name. Another cause is that you misspelled the command name (typo) or the sysadmin administrator does not install the command on your Linux/UNIX based system. To get rid of this error, try the following suggestions:
All Linux and UNIX commands are case sensitive, and you need to type the correct spelling of the command.
PATH is an environment shell variable that shows the different directories that your shell will see in order to find commands. You can see the current search path with the following echo command/printf command:
$ echo "$PATH"
$ printf "%s\n" "$PATH"
Sample outputs:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/local/bin:/home/vivekgite/bin
Usually, all user commands are in /bin and /usr/bin or /usr/local/bin directories. All your programs are installed in these directories. When you type the clear command, you are running /usr/bin/clear. So if it is not in your PATH, try to add directories to your search path as follows (setup Linux or UNIX search path with following bash export command):
$ export PATH=$PATH:/bin:/usr/local/bin
You can also find out of the path using which command or whereis command or type command/command as follows:
$ which ls
/bin/ls
$ which gcc
/usr/bin/gcc
$ which date
/bin/date
$ which cal
/usr/bin/cal
$ whereis gcc
/usr/bin/gcc
$ type -a gcc
gcc is /usr/bin/gcc
gcc is /bin/gcc
$ type -a time
Here is how it looks:
time is a shell keyword
time is /usr/bin/time
time is /bin/time
$ command -V time
time is a shell keyword.
You can run a program using its full pathname. For instance, run ls as /bin/ls:
$ /bin/ls
$ /bin/date
Permission problem
Finally, sometimes you may not have permission to run the command. Remember, all Unix or Linux commands or scripts must have executable permission set. We can verify (view file permission) this using the ls command:
$ ls -l /bin/ls
$ ls -l ~/bin/toc
Outputs indicating my custom script called ~/bin/tochel has executable permission for user, group, and others:
-rwxrwxr-x 1 vivek vivek 132 Oct 19 00:31 /home/vivek/bin/toc
We can display file information and status easily by using the stat command:
$ stat /bin/ls
macOS Unix desktop or Linux desktop file manager also displays file permission. Make sure you have executable permission:
Of course, we can use the chmod command to set executable permission:
$ chmod +x filename
$ chmod +x /path/to/filename
## sysadmin level permission needed for other users ##
$ sudo chmod +x /path/to/file.sh
Run the command as the root / superuser
Some commands need privileged access. Hence run it as follows:
sudo command
sudo /path/to/command
sudo -u userName command2.
Good luck🌾
Try with :
sudo apt-get install freeglut3-dev
sudo apt install libopengl0

Akila Wickramasekara didn't work...still getting the same error even though it says:
Make sure /usr/local/bin/vmd is in your path.
VMD installation complete. Enjoy!
once I type 'vmd' it says
/usr/local/lib/vmd/vmd_LINUXCARMA: Command not found.
