Hello ,
I am a new Spanish user of root and is the first time I program in C++,
I have done a simple example from root user guide (a canvas that is
divided in four pads) and i add one graph in each one, but while in root
interpreter it works fine, when I try to compile the program with gcc-2.95
in a linux Mandrake 7.2 including the shared librarys provided with ROOT
it links without any problem but when I execute the program a core dumped
message is returned.
This the C++ code(prueba.C):
#include "TCanvas.h"
#include "TGraph.h"
#include "TF1.h"
void main(){
TF1 f1("fun1","sin(x)/x",0,10);
TF1 f2("fun2","sin(x)/x",-5,5);
TF1 f3("fun3","x^2",0,10);
TF1 f4("fun4","x^2",-5,5);
TCanvas * MyC =new TCanvas("MyC","Test Canvas",1);
MyC->Divide(2,2);
MyC->cd(1);
f1.Draw("AC*");
MyC->cd(2);
f2.Draw("AC*");
MyC->cd(3);
f3.Draw("AC*");
MyC->cd(4);
f4.Draw("AC*");
}
this is the makefile:
CC = g++
LIB=-lCint -lCore -lEG -lGX11 -lGX11TTF -lGpad -lGraf -lGraf3d -lGui -lHist -lHistPainter -lHtml -lMatrix -lMinuit -lNew -lPhysics -lPostscript -lProof -lRGL -lRint -lThread -lTree -lTreePlayer -lTreeViewer -lX3d
EXEC = prueba
I = /home/emilio/root/include
$(EXEC) : prueba.o
$(CC) -I$(I) $(LIB) -o $(EXEC) prueba.o
prueba.o : prueba.C
$(CC) -I$(I) -c prueba.C
Is obvious that I am a new C++ user on unix seing the code of the makefile
i have always programmed on windows platform with visual or borland C++
but one day I thought why not unix, why not free...
The last question, is possible to run root on Mandrake 8.0 and there are
some advantages respect 7.2 version.
Thanks
