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... 0x4068b65e in G__scratch_globals_upto + 0x27 from /home/dgrant/root/lib/libCint.so 0x40176439 in TCint::ResetGlobals() + 0x21 from /home/dgrant/root/lib/libCore.so 0x4013a698 in TROOT::Reset(char const*) + 0x32 from /home/dgrant/root/lib/libCore.so 0x08049067 in main + 0x2f from matread 0x42015574 in __libc_start_main + 0xe4 from /lib/tls/libc.so.6 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
