I can not load any script two times

ROOT

Hello,
after I changed the ROOT version to the last(24.00) I can not load the same script two times:

root [0] .L lambda_fit_one1_histogram.C
root [1] .L lambda_fit_one1_histogram.C

What is wrong?

Hi,

What is the content of your script?

Philippe.

OK,
I’ve found that this error messages occur only for scripts with headers,
like these:
#include <stdio.h>
#include
#include
#include
#include “TMinuit.h”
#include “TH1.h”
#include “TStyle.h”
#include “TH2.h”
#include “TH3.h”
#include “TProfile.h”
#include “TF1.h”
#include "TFile.h"
using namespace std;

and no messages for scripts without headers.

Often I have the script of such structure:

headers
int main(par1,par2,…) {
code
}

and I run it in two modes:
1)outside the ROOT I compile & link it and then run it as executable module
2)Inside the ROOT I
.L script.c
main(par1,par2,…)

It seems to run such script in ROOT I must delete the header lines?
What is the way to avoid such code change? :question:

Regards
Oleg

Hi,

I will check why this is crashing. In the meantime you can hide the header from CINT by using:

#ifndef __CINT__ #include <stdio.h> #include <iostream> .... #endif // __CINT__

Cheers,
