Unable to compile root programs outside root environment

[bellenot]

Hi,

@Debajyoti_Sengupta

This is my code ( I save it as a .cpp file and try to execute it outside root using g++ (filename).cpp) and i get the error :

Which version of ROOT do you use exactly? if it’s the native one, you have to compile with cl.exe, not g++
And see also Posting code? Read this first!

Cheers, Bertrand.
