RooUnfold installation

[NadaBarakat]

Dear Rooters,
I am trying to install RooUnfold package (RooUnfold-1.1.1) locally on my fedora. I have install root-6.04.18 and enabled roofit while configuring and installing root.

When I am typing “make” inside the RooUnfold directory I am getting the following error:
In file included from /usr/include/c++/4.9.2/atomic:38:0,

I have tried to decalre a new variable in the MakeFile

ADD_LIB_GPP = -L/usr/lib/gcc/x86_64-redhat-linux/4.9.2 -lstdc++

But this didn’t solve the problem.
Your help is appreciated.

Best Regards,
Nada

Hi Nada,

I am not familiar with the build system of RooUnfold, however the message clearly indicate that RooUnfold needs to be build in C++11 mode. I.e. ‘something’ needs to be done in the RooUnfold configuration step to lead to the inclusion of “-std=c++11” to the compilation line.

Cheers,
Philippe.
