Variable declared as an 'inline' field in c++14

[scsc]

Tried to run an example using C++14/17 styles. But got these errors similar to this:

 error: ‘created’ declared as an ‘inline’ field
   inline static size_t                created{ 0u };

Doesn't 14 or 17 support this "inline" feature? Both "-std=c++14" and "-std=c++17" generated the same errors.

C++17 supports the inline static syntax (see https://en.cppreference.com/w/cpp/language/static). So you need to have a C++17 capable compiler and specify the language level accordingly. In C++14 this is not supported....

I think I had also already specified C++17 already:

g++ -c -g -Wall -std=c++17 -DSC_INCLUDE_FX -DSC_INCLUDE_DYNAMIC_PROCESSES -I. -I/opt/systemc/include

But still got that "inline" error. I am using g++ version 

g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.12) 5.4.0 20160609

looking at the g++ manual, there is no c++17 but c++1z. But even with "-std=c++1z", the errors still persist. What version of g++ are you using to support this feature?

The answer is here:

This particular g++ version doesn't support full c++17 features.
