In comparison, -lpthread will only do the second part, i.e.At link time, the linker will specifically link the resultant object.At compile time, -pthread manifests that the Pthread API is requestedĪnd defines platform-specific macros, such as _REENTRANT on Linux.The -pthread option sets flags for both the compiler preprocessor and linker.I went down the rabbit hole to discover the difference between -pthread and CMake-generated build trees created for projects that use the ENABLETESTING and ADDTEST commands. That, Linux machines should also make use of -pthread, according to the The ctest executable is the CMake test driver program. To both compile and link POSIX-compliant multi-threaded applications. Whether to use -lpthread or the compiler command line option -pthread.Īfter some digging, I discovered that clang compilers require using -pthread GTest requires Pthreads to compile, so it seemed like I need This resulted in linker errors and warnings about undefined references to The library needs to be in place to link against it, so first install theĬlang++ **/ *.cc -lgtest -lgtest_main &. Example CMakePresets.json file Next steps CMake supports two files that allow users to specify common configure, build, and test options and share them with others: CMakePresets.json and CMakeUserPresets.json.To manually link against the test framework and produce a test executable thatĬan be run from the command line, do the following: The tools!) Manually Linking against GoogleTest (This is what I do for “fun”, in the workplace I play by the rules and use all Using the terminal and nothing else, I can avoid the overhead of an IDE andĬMake, and as a nice bonus, my directories are decluttered of IDE files. Projects like the ones I complete for my BSc. As a minimalist approach, it also works really well for small-scale This file will house a CMake helper function, addboosttest which will be used to generate a test runner usable by CTest from a single test source file. Next, create a text file called BoostTestHelpers.cmake. To begin, Boost.Test must be included in the project. It’s good to do things the hard way sometimes and good practice to remember General Testing Information In your main CMakeLists.txt you need to add the following function call (not in a subfolder): if(CMAKEPROJECTNAME STREQUAL PROJECTNAME) include(CTest) endif() Which will enable testing and set a BUILDTESTING option so users can turn testing on and off (along with a few other things ). This article assumes that a CMake based project already exists. ![]() ![]() ![]() You might think I’m a masochist for foregoing a standard setup in favour of The top level directory has two subdirectories called. Make sure that you have CMake installed prior to running this example (go here for instructions). It’s generally used with a build system like CMake or Bazel. The following example demonstrates some key ideas of CMake. GTestĬan be used for any kind of tests, not just unit tests, and has some niceįeatures like automatically detecting tests and playing nicely with your IDE. Im running into an issue where even though Ive got my CMake set up correctly (builds just fine on Clion, running on top of Visual Studio) - for example. GoogleTest (or GTest) is Google’s testing and mocking framework for C++. Without CMake for small-scale C++ projects. In this post, I’m going to explain how I went back to basics and used Back to basics: using GoogleTest without CMake for C++ projects | TP Home Résumé About Blog Projects Back to basics: using GoogleTest without CMake for C++ projects 29 April 2021
