Root executable not found after a successful `make install`, `root-config` is found anyway

[Javier_Galan]

I have pulled root from Git, compiled on 6.20/04 using cmake from the build directory.

Everything seemed to work fine, I have even root-config command accessible.

source /path/to/install/thisroot.sh
root-config --version

gives 6.20/04.

However no root executable is found. I had to disable X11, I have previously compiled and installed root on other systems with this version. The difference now is that I am disabling X11.

My bin directory looks like this

No trace of the usual root executable in Linux.

Use “root.exe”.

[Javier_Galan]

Ok, I see that works. But why the standard root executable disappeared from my installation?

[amadio]

root is just a wrapper around root.exe and is only available when X11 is enabled. It handles some environment variables, the splash screen, etc. Just use root.exe, as suggested by @Wile_E_Coyote.

[Javier_Galan]

Ok, thanks, I had to do a ln -s root.exe root at my local installation bin to work around other scripts directly using the wrapper.
