Hello,

What is exactly what you are executing?

Are you trying to run a macro? What is the command you are using?

Hi,
I’m trying to execute the macro code.C and it had one argument data.txt.

I used the command .x code.C data.txt

I assume your current working directory is `/home/xgh/build/macros`?

Please make sure that both `code.C` and `data.txt` are in `/home/xgh/build/macros`, or move to the directory where they are before running `root` and then `.x code.C data.txt`.

Both `code.C` and `data.txt` are in the directory `/home/xgh/build/macros`. Still the same error is coming up.

Hi,

Then, assuming you did

`cd /home/xgh/build/macros`
`root`

this should work, from the ROOT prompt:

`.x code.C("data.txt")`
