<atomic> is not implemented

ROOT
1

Hello,

I am already using root-6.04.02 on my Mac OSX 10.10.5. Now I am trying to compile someone elses C++ code. The code, however, contains some root features:

[code]#include
#include
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <TMath.h>
#include <time.h>
#include <TGraph.h>
#include <TF1.h>
#include <TH1F.h>
#include <TCanvas.h>
#include <TRandom.h>
#include <TFile.h>
#include <TNtuple.h>
#include <TTree.h>
#include <TApplication.h>
#include <TROOT.h>
#include “Temperature.h”
#include “SetInitialPosAndVel.C”

using namespace std;[/code]

When trying to compile with the MakeFile

[code]FLAGS = -I/Users/ingmaritietje/Documents/root-6.04.02/include
LIBS = $(shell root-config --glibs)

Temperature: Temperature.o
g++ -Wall -o Temperature Temperature.o $(LIBS)

Temperature.o: Temperature.C
g++ -Wall -c $(FLAGS) Temperature.C

clean:
rm *.o[/code]
Here is some part of the error code:

I read through some related posts from before, so I think I have to alter the MakeFile in a way, that makes it use clang and support c++11. How can I apply the changes?
Is there something else missing?

Best, iMi

Add ‘-std=c++11’ into the FLAGS

I added ‘-std=c++11’ into the flags.

[code]FLAGS = -I/Users/ingmaritietje/Documents/root-6.04.02/include
LIBS = $(shell root-config --glibs)

Temperature: Temperature.o
g++ -Wall -o -std=c++11 Temperature Temperature.o $(LIBS)

Temperature.o: Temperature.C
g++ -Wall -c -std=c++11 $(FLAGS) Temperature.C

clean:
rm *.o[/code]

I now get a much shorter error message, but still an error message:

make g++ -Wall -o -std=c++11 Temperature Temperature.o -L/Users/ingmaritietje/Documents/root-6.04.02/lib -lGui -lCore -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lMathCore -lThread -lpthread -Wl,-rpath,/Users/ingmaritietje/Documents/root-6.04.02/lib -stdlib=libc++ -lm -ldl clang: error: no such file or directory: 'Temperature' make: *** [Temperature] Error 1

Btw: I managed to run the same code (with minor changes) in root, but of course I’d like to get it running with c++ as well.
Best,iMi

-std=c++11 -o Temperature

5

or

FLAGS = -I/Users/ingmaritietje/Documents/root-6.04.02/include -std=c++11

which was what I suggested.

Thanks a lot! It works now.
