Compiling twitter application in Linux environment #5
Description
Hi Kirk and everybody,
I am trying to build the twitter application in the Linux environment (Ubuntu 16.04.2 LTS) with gcc 6.3.0, I had no problems installing the environment with cmake files, all the libraries (i.e: rxcpp, range-v3) download, compile and execute their examples without problems, but when I try to compile the twitter app some error are reported by the compiler. I have not modified the compilation flags defined in "shared.cmake". To solve some of the first batch of error I have included "chrono" and "condition_variable", but after this modification two errors are raised. Below, I copy the compiler error dump. What do you think about the error?
Best Regard, and thanks in advance.
Pedro.
