Hi
I have come across an error I dont understand in running some root code.
I have tried to include the
gROOT->Reset();
command in my code. I compile without errors but when I run the code I
get the following error:
*** Break *** segmentation violation
Generating stack trace...

0x08048f9d in TFile::TFile[in-charge](char const*, char const*, char
const*, int) + 0x31 from matread
Abort (core dumped)
A simplified version of the code is:
#include <cstdio>
#include <iostream>
#include <string>
#include "TFile.h"
#include "TTree.h"
#include "TH2.h"
#include "TCanvas.h"
#include "TVector.h"
#include "TROOT.h"
#include "TCint.h"
using namespace std;
TROOT rootBase("analysis","ROOT analysis environment");
int main()
{
gROOT->Reset();
TFile *file = new TFile ("test.root", "RECREATE");
TTree *tree = new TTree ("tree", "Testing");
}
And this is compiled with a makefile:
# Makefile
#
ROOTLIBS = $(shell root-config --libs) -lMinuit #-lTable
-lHtml
ROOTGLIBS = $(shell root-config --glibs)
ROOTINCLUDE ?= $(shell root-config --incdir)
MATLABDIR = /data4/dgrant/Matlab_Inst/extern/lib/glnx86
MATLABD2 = /data4/dgrant/Matlab_Inst/bin/glnx86
CXX = g++
CXXFLAGS = -O2 -Wall -fPIC -I$(ROOTINCLUDE)
OBJS = matread.o
matread: $(OBJS)
$(CXX) $(CXXFLAGS) $(ROOTLIBS) $(ROOTGLIBS) -L$(MATLABDIR) -lmat
-lmx -l
mmfile -lmwservices -L$(MATLABD2) -lmatlb -lmex -lmwmpath -lmwudd -o $@ $^
matread.d: matread.cxx
@echo "Generating dependency file $@"
@set -e; rm -f $@
@$(CXX) -M $(CXXFLAGS) $< > $@.tmp
@sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.tmp > $@
@rm -f $@.tmp
include matread.d
matread.o: matread.cxx matread.h
$(CXX) -c $(CXXFLAGS) $<
clean:
rm -f *.o
rm -f *.d
Has anyone come across this before and maybe offer some advice?
Thanks so much!
Cheers
Darren
