Old code for school does not compile with ROOT 6.08/02

[rzei]

Hi,
I tried to compile old code made for school with a basic Makefile like this

CXXFLAGS = -O
LDFLAGS = -O 
SRCS = $(wildcard *.cpp)
HEADERS = $(wildcard *.h)
OBJECTS = $(SRCS:.cpp=.o)

ROOTLIBS      = $(shell root-config --libs)
ROOTGLIBS     = $(shell root-config --glibs)

all: Pianeti PianetiAnimati

.C.o: $(SRCS) $(HEADERS)
	c++ $(CXXFLAGS) -c -I. $<

Pianeti: $(OBJECTS)
	c++  $(LDFLAGS) -I$(ROOTSYS)/include -I. -o $@ Pianeti.C $(OBJECTS)

PianetiAnimati: $(OBJECTS)
	c++ $(LDFLAGS) -I$(ROOTSYS)/include -I. -o $@ PianetiAnimati.C $(OBJECTS) $(ROOTGLIBS)

clean:
	rm -f *.o

but I cannot create “PianetiAnimati” (everything else is OK!).
I’m using ROOT 6.08/02 on Ubuntu LTS 16.04.2 with gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

What can I do?

CorpoCeleste.cpp (918 Bytes)
CorpoCeleste.h (837 Bytes)
SistemaSolare.cpp (414 Bytes)
Pianeti.C (1.6 KB)
vettore.h (777 Bytes)

What error is reported?

Hi,
the error seems very “basic”: error: #error “ROOT requires support for C++11 or higher.”

The complete output is in the attached fileerror.txt (94.7 KB)

I’m using the following ROOT version https://root.cern.ch/download/root_v6.08.02.Linux-ubuntu16-x86_64-gcc5.4.tar.gz on Ubuntu 16 gcc5.4

Thanks

Your code need to be compiled in C++11 mode:

@rzei

CXXFLAGS = -O -std=c++11
LDFLAGS = -O -std=c++11

and/or use the result of root-config --cflags
