I have a mac book pro and i am only able to run root macros on my terminal but I need to run the tutorials.

Pls, how can I run the tutorials on my terminal?

MY TERMINAL OUTPUT

abis-MacBook-Pro:~ abi$ /Users/abi/root/tutorials/hsimple.C 
-bash: /Users/abi/root/tutorials/hsimple.C: Permission denied

abis-MacBook-Pro:~ abi$ cd root/bin
abis-MacBook-Pro:bin abi$ ./root.exe

//hsimple.C is in the ROOT tutorials directory
root [0] .x hsimple.C
Error in <TApplication::ExecuteFile>: macro hsimple.C not found in path .:/Users/abi/root/macros
root [1]

I don’t understand what your issue is. How would you like to run the macros? Using the terminal is the usual way.

You will find all the tutorial in $ROOTSYS/tutorials.
cd ro this directory (or copy the tutorials from there) and the you will be able to execute them as at the ROOT prompt. As @amadio said this is the only way to run ROOT macros.

Question updated for clarification. pls take a look at it…

Hi,
that error is normal. hsimple.C is, in fact, not in ‘/Users/abi/root/macros’.

Open your terminal, setup ROOT’s environment (if you don’t do it automatically in your .bashrc script) with source /Users/abi/root/bin/thisroot.sh, then do a cd /Users/abi/root/tutorials, and from the root prompt you can now type .x hsimple.C because hsimple.C is now in your current directory.

Tried your suggestion, but I got a permission denied.

8

At which point? I just suggested to cd into the tutorials directory and the execute root from there.
If that does not work you might have some issues with your ROOT installation.

9

okay thanks… the problem is with the installation which i am yet to figure out.

10

i keep getting the “permission denied” prompt in the terminal.

You are really not giving us much information here :slight_smile:
How did you install ROOT? Which command gives you a permission denied error exactly?

If your aim is simply running hsimple.C from the ROOT prompt, you can do
source /path/to/root/bin/thisroot.sh (where I think your /path/to/root is /Users/abi/root) and then start root (just type root and press enter). From ROOT’s prompt you can execute any tutorial if you know its location. I think in your case it should be
root[0] .x /Users/abi/root/tutorials/hsimple.C
but you probably know your system better than me :smiley:

I have tried to modify the info you gave in your 1st post. Several things were wrong. It should be something like:

$ cd ~/root
$ . bin/thisroot.sh
$ cd tutorials
$ root

root [0] .x hsimple.C
root [1]

Note that the 2nd line should be put in your .bashrc file to avoid re-typeing this commend each time you start a new terminal.

The message permission denied you get is because your tried to execute hsimple.C at the shell prompt … it is a ROOT macro … it should be executed in ROOT…

I assume ROOT binaries are installed in your directory ~/root … it seems it is, given the terminal output you posted.
