Hi,
I've installed protobuf version 3.6.1 on Ubunto 16.04 without errors (as
described in "readme.txt" - protobuf package). When I tried to run your
example (i.e. "add_person/list person") I got the *following error:*
*error: #error This file requires compiler and library support for the ISO
C++ 2011 standard. This support must be enabled with the -std=c++11 or
-std=gnu++11 compiler options*.
Please find the attached file to this post.
*Note:*
I saw that this version (3.6.1) required C++11 So I do the following
installations and it still didnt help.
- $ sudo apt-get update
- $ sudo apt-get upgrade
- $ sudo apt-get install build-essential
- $ gcc -v
- $ make -v
Please advice,
BR ,
