Compile and run THttpServer

[Sayan_Ghosh]

How can I compile and run a HTTP server using THttpServer class? If I try

#include <THttpServer.h>
#include <TGraph.h>

int main() {
    THttpServer *serv = new THttpServer("http:8080");
    TGraph* gr = new TGraph(10);
    gr->SetName("gr1");
    serv->Register("graphs/subfolder", gr);
}

the code compiles but the server immediately stops. Although in root interpreter it works fine.

Is there a tutorial on how to compile and run such a server using cmake/g++?

Welcome to the ROOT Forum!
You need an instance of TApplication to process the events:

#include <TApplication.h>
#include <THttpServer.h>
#include <TGraph.h>

// cl -nologo -O2 -MD -GR -EHsc -Zc:__cplusplus -std:c++17 -I%ROOTSYS%\include httpserver.cxx /link -LIBPATH:%ROOTSYS%\lib libCore.lib libGui.lib libGpad.lib libHist.lib libTree.lib libGraf.lib libRoofit.lib libRoofitCore.lib libRHTTP.lib /out:httpserver.exe

int main(int argc, char* argv[])
{
   TApplication mainApp("mainApp", &argc, argv);
   THttpServer *serv = new THttpServer("http:8080");
   TGraph *gr = new TGraph(10);
   gr->SetName("gr1");
   serv->Register("graphs/subfolder", gr);
   mainApp.Run(kTRUE);
   return 0;
}
