// Hello! // These days I tried to use ROOT to draw some histograms like the ones // shown at the ROOT webpages. It didn't work... // Well, it's fine to have a C Interpreter, but I liked to use ROOT's // functions in compiled programs. I hoped: some calls, and I have a pic/histogram... // Why doesn't it work? // It compiles w/o problems, but gives no output, esp. no grafical... // Didn't I correctly understood the idea of ROOT at all? It seems to work fine // via the interpreter (ROOT shell)... // Sincerly yours, Andre Merzky. //___________________________________________________________________________ //TEST.C - Test Root //___________________________________________________________________________ #include <stdio.h> #include "TROOT.h" #include "TApplication.h" #include "TCanvas.h" #include "TPaveLabel.h" //___________________________________________________________________________ void main (void) { TROOT blub("Test", "Test of ROOT..."); // btw: where is this call documented? TCanvas *c1 = new TCanvas("c1"); c1->Range(0,0,1,1); TPaveLabel par(0.1,0.8,0.9,0.95,"Example"); par.SetFillColor(42); par.Draw(); return; } // PS.: // compiled with: // CC -I. -I/apps/software/root/include -I/usr/include \ // +a1 +Z -O -w -c -o test.o test.C // CC -O -g +a1 -z test.o -o test \ // -L/apps/software/root/lib \ // -lBase -lCint -lClib -lCont -lFunc -lGraf -lGraf3d -lHist - \ // -lHtml -lMeta -lMinuit -lNet -lPostscript -lProof -lTree -lUnix \ // -lZip -lGpad -lGX11 -lMotif -lWidgets -lX3d
