Symbol lookup error: undefined symbol ZN7TStringC1ERKNSt7

[oochoav]

Dear ROOTers,

I come to you for some help and guidance. I’m currently running a fitting software called Gfitter, which has to be compiled against ROOT. I’ve managed to properly load and install ROOT v5.34.34 my laptop (macOS Sierra 10.12.6, cmake 3.9.2). Following the same steps as in my laptop’s installation, I installed the same ROOT version in my desktop (CentOS Linux 7, cmake3 3.6.3).

In my laptop, Gfitter+ROOT run smoothly. However, when trying to run it in my desktop, I get the following error:

The error looks like one of the ROOT libraries is not properly loaded (TString class). In order to cross-check what’s going on, I went in my laptop to the directory where the ROOT libraries are installed and typing:

$ for i in ls *.so; do echo $i; nm $i | grep _ZN7TStringC1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE; done

I see

libCore.so
10639:00000000000ba450 T _ZN7TStringC1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

which means that this symbol resides in libCore.so . However, when doing so in my desktop, the most I get for libCore.so is

libCore.so
000000000050c2f0 T _ZN7TStringC1Ec
000000000050c310 T _ZN7TStringC1Eci

000000000050c3c0 T _ZN7TStringC1ERK10TSubString

000000000050c250 T _ZN7TStringC1ERKSs
000000000050c100 T _ZN7TStringC1Ev

Any ideas on how to fix this issue?

Kind regards,

Oscar.

Looking at:

[...]$ c++filt _ZN7TStringC1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
TString::TString(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)

it seems to me that your “libGfitter.so” was compiled with C++11 support while your ROOT version was not.
