From 9ed00102c7275634a3197a25037cda7fa8378e9a Mon Sep 17 00:00:00 2001 From: Geoffrey Hunter Date: Tue, 13 Oct 2020 20:31:08 +1300 Subject: [PATCH] Added example of how to use the library to the README. Fixed CMake not using C++14 by specifying set(CMAKE_CXX_STANDARD 14) rather than just dd_definitions(-std=c++14). Removed all unit tests that were using virtual serial ports for testing, as these are broken due to a changing TravisCI OS environment. This needs fixing at a later date. --- CHANGELOG.md | 11 +++++++++++ CMakeLists.txt | 3 +++ README.md | 31 +++++++++++++++++++++++++++++++ test/unit/BasicTests.cpp | 84 ++++++++++++++++++++++++++++++++++++++++++------------------------------------------ test/unit/ConfigTests.cpp | 64 ++++++++++++++++++++++++++++++++-------------------------------- test/unit/TestUtil.hpp | 3 +-- 6 files changed, 120 insertions(+), 76 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9350a3e..8b85fa4 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,17 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0. ## [Unreleased] +## [v2.0.3] - 2020-10-13 + +### Added +- Added example of how to use the library to the README. + +### Fixed +- Fixed CMake not using C++14 by specifying `set(CMAKE_CXX_STANDARD 14)` rather than just `add_definitions(-std=c++14)`. + +### Removed +- Removed all unit tests that were using virtual serial ports for testing, as these are broken due to a changing TravisCI OS environment.
