GCC version for C++11

[amaroyo]

Hi,

I am using macOS and I was using the function std::to_string(myDoubleVar); which is working fine. However, I was compiling it in the linux setup and it's not recognized 'to_string' is not a member of 'std'

It seems that the function is C++11, but I thought we were using already the C++11.

Any ideas? Do we need to upgrade the linux setup with a newer version?

Thanks,
Alex.

Hi @amaroyo,

C++11 is not enabled by default on Linux yet, or at least on certain flavors/versions of Linux; therefore, you have to explicitly tell CMake to compile the code with C++11 features enabled.

There are multiple ways of doing this. If you have CMake 3.1, try the following directive:

set(CMAKE_CXX_STANDARD 11)

C++11 (actually C++14) will be the default from GCC 6.1 (https://gcc.gnu.org/projects/cxx-status.html#cxx14). The first Ubuntu version with it I think is Ubuntu 16.10 .
