Dear Sirs,
I would like to use the multinomial distribution function in Math/GSLRndmEngines.h

I included the GSLRndmEngines.h,
and then I wrote down these lines

vectorproba;

ROOT::Math::GSLRngMT * random;
random->Initialize();
vector evtsPerChannel = random->Multinomial(4, proba);

and then I got this errors

ndefined symbols:
“ROOT::Math::GSLRandomEngine::Initialize()”, referenced from:
pseudoexp_generation() in pseudoexp_generation_C_ACLiC_dict.o
"ROOT::Math::GSLRandomEngine::Multinomial(unsigned int, std::vector<double, std::allocator > const&) const", referenced from:
pseudoexp_generation() in pseudoexp_generation_C_ACLiC_dict.o
"_main", referenced from:
start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
*** Interpreter error recovered ***

What could I do?
Bets Regards

Hi,

Before running ACLC on your macro try to do from the root prompt

root [0]  gSystem->Load("libMathMore")

Best Regards

This is the output

root [0] gSystem->Load(“libMathMore”)
Error in TUnixSystem::DynamicPathName: libMathMore[.so | .sl | .dl | .a | .dll] does not exist in /Users/fabrizioruffini/root_v5_27/lib:/Users/fabrizioruffini/root_v5_27/lib::/Users/fabrizioruffini/root_v5_27/lib::.:/Users/fabrizioruffini/root_v5_27/lib::/Users/fabrizioruffini/root_v5_27/cint/cint/stl

I assumed that in the version 27 I’m using the library was included. Was I wrong? Do I need to install a new release?

[quote]I assumed that in the version 27 I’m using the library was included.[/quote]Which version? How/where did you download it (from)?

I strongly recommend (if possible) to upgrade to v5.30.

Cheers,
