invalid argument '-std=c++11' not allowed with 'C/ObjC'

This kind of message indicates that there is a problem with your XCode and ROOT installation.

This problem is discussed on the ROOT forum:

​http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=17190&start=75

The solution is to
 - upgrade to the latest Xcode
 - install the latest command line tools
 - built the latest ROOT from sources
 - point all the environment variables to the correct compiler installation
 - point all the environment variables to the correct ROOT installation directory

Recently, I've tested this solution myself.

Here is what I've done to correctly build ROOT and Delphes under Mac OS X 10.9:

 - removed old MacPorts - https://guide.macports.org/#installing.macports.uninstalling

 - installed XCode 5.1 - https://developer.apple.com/downloads
 - installed XCode command line tools - "xcode-select --install"

 - installed XQuartz 2.7.5 - https://xquartz.macosforge.org/landing/

 - installed MacPorts 2.2.1 - http://www.macports.org/install.php

 - installed ROOT 5.34.18 using the following commands:
{{{
version=5.34.18
export ROOTSYS=$HOME/root/root-${version}

curl -O ftp://root.cern.ch/root/root_v${version}.source.tar.gz
tar zxf root_v${version}.source.tar.gz

cd root

./configure macosx --enable-gdml --enable-minuit2 --enable-roofit --enable-table --enable-unuran --disable-cocoa

make -j 4
make install
}}}

 - installed Delphes using the following commands:
{{{
# setup ROOT environment variables
export ROOTSYS=$HOME/root/root-5.34.18
export PATH=$ROOTSYS/bin:$PATH
export PYTHONPATH=$ROOTSYS/lib:$PYTHONPATH
export DYLD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH

wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.1.2.tar.gz
tar -zxf Delphes-3.1.2.tar.gz

cd Delphes-3.1.2
make -j 4
}}}

Thank you Pavel

but now I have problems with Root compilation

clang++ -O2 -m32 -pipe -Wshadow -W -Wall -Woverloaded-virtual -fsigned-char

Sorry, I don't know how to help you with this problem. May be you can try to contact ROOT support with this problem.

Were you following the steps that I posted earlier?

yes I were. Thank you. Regards Patricia

Patricia, you have already installed the root package? If the answ is yes then try to do the following;

First on the root folder make ..... root$ . bin/thisroot.sh
after of that go to the MG5 folder.....mg5> install ExRootAnalysis

In my case the above worked, but remember first compiling the "root" package.

Best

Hi Daniel, I could not install either Root or ExRootAnalysis yet in my Mac. The same errors persists. The emergency solution was to install a Virtual Machine wih Ubuntu. There works fine.

If you have any news about it please let me know.

Cheers Patricia

Dear authors

still trying to solve Exrootanalysis at Mac OS 10.9 (Maverick)

I have installed the new Root6 through mcports but I still receive the same error msg

>> Compiling tcl/tclObj.c
error: invalid argument '-std=c++11' not allowed with 'C/ObjC'
make: *** [tmp/tcl/tclObj.o] Error 1

Moreover, in my .bash_profile I have

export ROOTSYS=/opt/local/libexec/root6
export PATH=$PATH:$ROOTSYS/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$ROOTSYS/lib

Would you have any new abour this issue?

Regards Patricia

Hi Patricia,

Just a comment.

The problem is not with ROOT installation but with the C++ installation.

Could you, please try to check what compiler is used when you're building ExRootAnalysis and that the path to this compiler corresponds to the path where the latest Xcode is installed on your system?

Cheers,

Pavel

Hi Pavel than you very much.

According Makefile

ifeq ($(ARCH),macosx64)
UNDEFOPT = dynamic_lookup
endif

SrcSuf = cc

CXXFLAGS += $(ROOTCFLAGS) -DDROP_CGAL -I. -Itcl -Imcfio -Istdhep -ICDFCones
-ICDFCones/CDFcode
LIBS = $(ROOTLIBS) $(SYSLIBS)
GLIBS = $(ROOTGLIBS) $(SYSLIBS)

it seems the compiler is "cc" and

pb-d-128-141-140-98:ExRootAnalysis prebello$ ls -alF `whereis cc`
lrwxr-xr-x 1 root wheel 5 Feb 18 06:50 /usr/bin/cc@ -> clang

I have Xcode installed but, since I am new at MAC OS X, I am not sure how
to identify if it corresponds to your request. Could you please guide me on
it?

Cheers Patricia

I've just looked through Makefile and got another idea.

Could you, please try to replace "gcc" with "$(CC)" at lines 946 and 951 in Makefile?

After the modification, the lines should look like the following:

        @$(CC) $(CXXFLAGS) -c $< $(OutPutOpt)$@

Hi Pavel

if you have meant these ones

$(TCL_OBJ): ....
        @$(CC) $(CXXFLAGS) -c $< $(OutPutOpt)$@

$(STDHEP_OBJ):...
        @$(CC) $(CXXFLAGS) -c $< $(OutPutOpt)$@

it didn`t work

Cheers Patricia

Yes, the lines are correct. Thanks for trying.

Could you try to remove the '@' character in front of the '@$(CC) $(CXXFLAGS)' lines and rerun 'make'? This will show the full command line used for compilation together with the command for compiler.

According to
http://stackoverflow.com/questions/5926232/find-xcode-installation-path-by-version
the command to find Xcode installation path is

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchS‌​ervices.framework/Versions/A/Support/lsregister -dump | grep -i --before-context=3 "com.apple.dt.Xcode" | grep --only-matching "/.*\.app"

Could you, please send me the output of this command and one full compilation command when running make without the '@' character?

Hi Patricia,

I think that I'm understand now why I can't reproduce this problem.

 From what I've found about the C++11 and ROOT on the ROOT's forum:

​http://root.cern.ch/phpBB3/viewtopic.php?f=21&t=16544

I'd say that MacPorts builds ROOT with the '--enable-cxx11' flag.

When I build ROOT, I don't use this flag.

When ROOT is built with the '--enable-cxx11' flag, the '-std=c++11' flag appears in the output of the 'root-config --cflags' and thus in the CXXFLAGS variable.

I can propose the following solution/workaround.

Could you try to replace the lines 946 and 951 in Makefile that normally look like

@$(CC) $(CXXFLAGS) -c $< $(OutPutOpt)$@

with the following expression

@$(CC) $(patsubst -std=%,,$(CXXFLAGS)) -c $< $(OutPutOpt)$@

Cheers,

Pavel

Dear Pavel,

thank you very much.

Could you please point me not the line but the whole "block" that I have to
change? My line 946 has $(STDHEP_EXECUTABLE_OBJ): tmp/%.$(ObjSuf): %.cpp
and the line
951 has $(STDHEP_EXECUTABLE): %$(ExeSuf): $(DICT_OBJ) $(SOURCE_OBJ)
$(TCL_OBJ) $(STDHEP_OBJ)

So it seems that they don`t match your Makefile structure.

Thank you.

Kind regards Patricia

The lines to be modified look like the following

$(TCL_OBJ):....
        @gcc $(CXXFLAGS) -c $< $(OutPutOpt)$@

$(STDHEP_OBJ):...
        @gcc $(CXXFLAGS) -c $< $(OutPutOpt)$@

Hi Pavel

thank you but, even after compiling in a new directory to avoid previous
mistakes after making the suggested changes, unfortunately I still receive
the msg

>> Compiling tcl/tclObj.c

It is really strange.

Hi Patrice,

Could you try to remove the '@' character in the beginning of the two modified lines and then rerun make?

After this modification the 2 lines should look like

        $(CC) $(patsubst -std=%,,$(CXXFLAGS)) -c $< $(OutPutOpt)$@

This will allow us to see the 'gcc ...' command that make generates.

Please send me the output of make after this modification.

Regards,

Pavel

The '@$(CC) $(patsubst -std=%,,$(CXXFLAGS)) -c $< $(OutPutOpt)$@' command solves this compilation problem.

I've just committed this modification to the MGTools repository and asked Olivier to make a new release.

Hi Patricia,

I've just prepared a new version of ExRootAnalysis that addresses all the problems that you discovered. I've also removed all the unneeded code and replaced the LHEF and STDHEP libraries with code from Delphes. This version reads STDHEP files much faster and it should be able to read LHEF v3 files.

It can be downloaded from

http://cp3.irmp.ucl.ac.be/downloads/ExRootAnalysis_V1.1.0.tar.gz

Could you give it a try?

Cheers,

Pavel

Of course Pavel. I am very glad to try it :-D

Cheers, Patricia.

Dear Pavel,

I have tested the MG5 with the released version of ExRoot here in my Mac
Maverick 10.9.4, with Root6.

It is working perfectly with PGS. :-D

Delphes cannot be compiled though, with the following error

Dear Patricia,

It seems that you are trying to use Delphes v2. This version of Delphes is not supported anymore.

I'd suggest to use Delphes v3 that is currenly the default Delphes version in MadGraph5.

However, the current Delphes v3 version won't work out of the box on your system (Mac OS X 10.9 with ROOT 6). I've just finished to adapt Delphes v3 to ROOT 6 and I expect to make a new Delphes v3 release in a couple of weeks.

You can download a snapshot of the Delphes v3 code repository from

https://github.com/delphes/delphes/archive/master.zip

This snapshot should work fine on your system.

Cheers,

Pavel

Perfect Pavel. It compiles and works. :-D

Nevertheless, although for PGS I can see the plots (that default ones
generated with topdrawer), in the case of Delphes the .top file is not fill
(although the plot_card.dat is present). No error msg.

Any missing detail for plotting the Delphes results like the PGS ones?

Cheers Patricia

Dear Patricia,

I'd say that MadGraph5 does not attempt to produce any plots from the Delphes output.

I'm not sure whether it would work and whether it's a good idea but you could try to convert .root file to .lhco file using root2lhco program provided with Delphes. Then you could try to use MadAnalysis (provided with MadGraph5) to produce the same set of plots that you obtain for PGS.

However, we expect the Delphes users to write their own macros/programs to analyze Delphes output as, for example, described in

https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/QuickTour

Other possibilities also exist to (semi-)automatically produce a basic set of plots:

 - DelphesAnalsysis

https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/DelphesAnalysis

 - MadAnalysis5

https://launchpad.net/madanalysis5

I would be interested to know which one of these methods you prefer.

Regards,

Pavel

Dear Pavel,

it is indeed very interesting and new for me. I have just known the
MadAnalysis5.

I will take a look on them more carefully. The Delphes`s root file is ok,
