Auto detecting your dev setup to initialize the default profile (/home/conan/w/prod/BuildSingleReference/.conan/profiles/default)
CC and CXX: /usr/bin/gcc, /usr/bin/g++ 
Found gcc 5.4
gcc>=5, using the major as version

************************* WARNING: GCC OLD ABI COMPATIBILITY ***********************
 
Conan detected a GCC version > 5 but has adjusted the 'compiler.libcxx' setting to
'libstdc++' for backwards compatibility.
Your compiler is likely using the new CXX11 ABI by default (libstdc++11).

If you want Conan to use the new ABI for the default profile, run:

    $ conan profile update settings.compiler.libcxx=libstdc++11 default

Or edit '/home/conan/w/prod/BuildSingleReference/.conan/profiles/default' and set compiler.libcxx=libstdc++11
