The old version would lead to error when Catch was installed
as a subproject. The file would be written to the subproject's
build directory and then would not be installed properly.
Create a namespaced Catch2::Catch target that is 'linkable' through
`target_link_libraries()` and export it so it is findable through
`find_package()`.
`find_package()` will find versions with the same major number and with
minor number >= requested.
This makes catch a lot easier to use in CMake-based projects. Whether it
is found using `find_package` or included in the client project as a
subdirectory, the client can include the catch headers per-target with
`target_include_directories(target PRIVATE Catch2::Catch).
Example usage:
cmake_minimum_required(VERSION 3.1)
# include Catch2 as subdirectory or installed package
# add_subdirectory(Catch2)
find_package(Catch2 VERSION 2.1.0 REQUIRED)
add_executable(tests tests/catch_main.cpp)
target_link_libraries(tests PRIVATE Catch2::Catch)
Also had to add new project to redirect CTest output, add
separate batch scripts for AppVeyor because it doesn't handle
multi-line batch scripts in yaml properly, and other helper
scripts.
* 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
to prevent inheritance of include directories that possibly lead to a clash.
A clash occurs when a folder is included, e.g. examples, that wants to use the single-include directory instead of the normal include directory as used by the SelfTest in the next higher level.
Also hides std::chrono, std::pair and std::chrono::* behind
new configuration macros, CATCH_CONFIG_ENABLE_*_STRINGMAKER
to avoid dragging in <utility>, <tuple> and <chrono> in common
path, unless requested.
Swept:
`-Wpadded` in some places (where it caused extra size, instead of just
saying "hey, we padded struct at the end to align, just as standard says")
`-Wweak-vtables` everywhere (Clang)
`-Wexit-time-destructors` everywhere (Clang)
`-Wmissing-noreturn` everywhere (Clang)
The last three are enabled for Clang compilation going forward.
Also enabled `-Wunreachable-code` for Clang and GCC
Note, this doesn't mean it will start passing, just that it will
run the approval tests properly
Some changes are needed before it passes, as the Windows output
somewhat differs.
- this file excluded from the CATCH_CONFIG_DISABLE_MATCHERS path.
- matchers are always compiled in to the impl file
- _THROWS_WITH macros are still available with matchers disabled - but only the ones that take a string
- tests that use matchers have #ifdefs, so the whole SelfTest project can compile with matchers disable.
Previously, some errors in Catch configuration would cause exceptions to
be thrown before main was even entered. This leads to call to
`std::terminate`, which is not a particularly nice way of ending the
binary.
Now these exceptions are registered with a global collector and used
once Catch enters main. They can also be optionally ignored, if user
supplies his own main and opts not to check them (or ignored them
intentionally).
Closes#921
Defining NO_SELFTEST=1 when cmake configuration is being done now turns
off SelfTest and Benchmark executables. This is for projects that
consume Catch using ExternalProject_Add and don't want to build our
selftest binaries for their unit test suite.
Closes#897
std::ifstream in libstdc++ contains a bug, where it sets errno to zero.
To work around it, we manually save the errno before using std::ifstream
in debugger check, and reset it after we are done.
We also preventively save errno before using sprintf.
Fixes#835
