IncrementalExecutor::executeFunction...unresolved while linking function

ROOT
,
1

Dear ROOT experts,

I have created a simple macro simulate.cc to build a TTree. However, when I run it using commands:

.L simulate.cc

I met this error:

IncrementalExecutor::executeFunction: symbol '__clang_call_terminate' unresolved while linking function '_GLOBAL__sub_I_cling_module_19'!

Any ideas for what is causing the problem?

Thanks!

Welcome to the ROOT forum.

If you search for _GLOBAL__sub_I_cling_module_19 in this forum, you will be directed to several posts which might help you.

Sorry, I still can’t find the solution. Could you please point out some useful posts?

Thank you so much!

PS: When I run it using .x simulate.cc

It becomes:

IncrementalExecutor::executeFunction: symbol '__clang_call_terminate' unresolved while linking function '_GLOBAL__sub_I_cling_module_56'!

Error in <HandleInterpreterException>: Trying to dereference null pointer or trying to call routine taking non-null arguments.
Execution of your code was aborted.

The problem is:

/home/mdr/simulate.cc:52:21: warning: null passed to a callee that requires a non-null argument [-Wnonnull]
        double energyInc = gr->Uniform(5, 10);

Check your code.

Hi @Anaya_Zhao,

It seems that your code might be calling a member function on gr, which is nullptr or otherwise dereferencing an invalid memory address.

Could you please provide a minimal reproducer of the problem?

Cheers,
J.

TRandom3 *gr = new TRandom3(0);

struct Track{
	double lenth;
};


vector<Track> collision(int wType){
	vector<Track> tracks;
	double energyInc = gr->Uniform(5, 10);
	return tracks;
}

int test(){
    return 0;
}

The file is named test.cc. After running the command .x test.cc I got the error:

IncrementalExecutor::executeFunction: symbol '__clang_call_terminate' unresolved while linking function '_GLOBAL__sub_I_cling_module_68'!

I wasn’t able to reproduce this locally. In principle, the code looks okay.

I think the problem might come from your environment. How did you installed ROOT (i.e. did you build yourself, via precompiled package, etc.)? Are you getting similar errors with other macro files?

Cheers,
J.
