This commits also adds a script that does the amalgamation of headers
and .cpp files into the distributable version, removes the old
`generateSingleHeader` script, and also adds a very simple compilation
test for the amalgamated distribution.
According to CMake, it does not support templated variables. Strictly
speaking, we added that to the target so that the project defaults
to C++14, but I am planning to use them inside Catch2 anyway.
* Use Xenial as the base distribution
* Remove C++11 builds
* Add a lot more C++14 builds
* Add some C++17 builds
* Include newer versions of Clang and GCC
Instead, let it be installed as a dependency of `conan-package-tools`
to avoid trouble with the fact that pip is really bad at version
resolution, and that up-to-date version of the `conan` package is not
supported by up-to-date version of the `conan-package-tools` package.
Last time it was fixed to a specific version because the `conan`
and the `conan-package-tools` package that `pip install` would
gather were not compatible, let's hope it won't happen again.
- The current setup tries to detect USE_CPP14/USE_CPP17 and sets the
CXX_STANDARD property for the SelfTest target. This is not ideal, since
CMAKE_CXX_STANDARD can be provided by the toolchain file or as command line
option and should be used by the library internally correctly. Hence, the
whole set of the relevant lines from `projects/CMakeLists.txt` have been
removed.
- The above can also cause subtle issues where the user is expecting the tests
to compile with C++17 after setting CMAKE_CXX_STANDARD and then getting
results of compilation with C++11 as USE_CPP17 has not been set.
- The current build matrix used the above code to run the tests. So, even
though the it should not required anymore to build Catch2, it was still
required to send correct options to build matrix. In that respect,
.travis.yml has been modified to send correct options to the build command
in the new setup.
The StringMaker is off by default and can be enabled by a new macro `CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER`, to avoid increasing the footprint of stringification machinery by default.
This means
* a new cmake option, `CATCH_BUILD_EXTRA_TESTS`, that conditionally
includes the ExtraTests subfolder
* building and running them on some of the Travis build images
* An example configuration test
In the future these should be extended to cover most of the
configuration options in Catch2, but this is a start.
This also goes for pkg-config installed by our CMake installation.
This includes
* Updating CMake version on Travis
* Adding a `Catch2` subfolder to the `single_include/` folder to
provide this include path both _inside_ the repository, and _outside_.
* Updated examples to build with the new paths
* Other general CMake cleanup
* Examples are no longer built on all travis images
* Coverage is no longer collected from all travis images
* Valgrind is no longer used with all travis images
This should greatly reduce the amount of compiling, downloading
binaries and general work the common images do.
* Every Linux build tracks coverage when running Debug mode
* OS X not supported yet (Future WIP)
* Our own unit tests, non-default reporters and Clara are ignored
- Added new compilers and OS X images
- Option to run SelfTest under Valgrind
- Merge "Debug" and "Release" configurations into one run
-- This saves apt setup and cmake download step per compiler, 60-90s
- Fix C++14 compilation under Clang 3.8 and up
* Removed ccache (it was slowing down the compilation for some reason)
* Enabled some C++11 builds (gcc 4.8, gcc 6, clang 3.8 for now)
* Added gcc 4.4, 4.7 and clang 3.4
The cmake download was failing, so we were relying on the old cmake,
which I broke recently (in 7ae96c710b).
Now the download should work again.
Also fixed warning that the requested OSX image no longer exists and
that it is automatically substituted for xcode 7.3 image.
