![]() In the new release, you can now open a single file or folder without using CMake, so that if all you want to do is to read some C++ code in CLion, you can work without CMake. This release also sees the first changes in the move to decoupling the CMake project model from CLion. ![]() CLion will use CMake, make, GCC/G++ compilers and debugger from WSL, and will build and run your binary there. You can connect to the toolchains by first starting WSL on the Windows machine, then connecting to the toolchain from CLion. The number of toolchains supported on Windows has been improved by adding WSL support. WSL makes it possible to compile, run, and debug Linux binaries while working on your Windows 10 machine. The support for WSL (Windows Subsystem for Linux) has also been improved. Code folding of the control statement has also been added. Unwrap/remove code blocks is a feature that safely unwraps if, else, for, while, do.while and for control statements. The breadcrumbs show information such as namespaces, classes, structures, functions, and lambdas to make the code easier to read and to navigate through. The editor is another area that has seen improvements, with the addition of Breadcrumbs for C/C++, and unwrap.remove code blocks.īreadcrumbs are small markers at the bottom of the editor that are designed to make it easier to navigate around code. While the developers are considering some alternatives to the current language engine in CLion, and expect to make changes in some 2018.x versions later in the year, the current version adds support for C++17 structured bindings, as well as support for C++17 if and switch with initializers. The developers say they've worked in several directions that may lead to better language support in the long run, including both accuracy and performance. The main improvements to the new release are in the area of support for C++. While C and C++ are the main languages CLion is designed for, the new release does come with bundled support for Objective-C and Objective-C++, as well as updated plug-ins for Rust and Fortran. Its advantages include a smart editor, code quality assurance, automated refactorings, and integration with the CMake build system. More generally, this version shows the start of the general decoupling of the CMake project model from CLion.ĬLion is an IDE from JetBrains that you can use to develop in C and C++ on Linux, OS X and Windows. Thus, one simply has to set this CMAKE_CXX_STANDARD to the highest standard requested by the dune modules.There's improved support for C++17 in CLion 2018.1 as well as WSL support and the addition of CMake Install. This can only be increased using a cxx_std_XXX feature requirement. How to increase the c++ standard for all dune modules? The cmake variable CMAKE_CXX_STANDARD is used for all targets in a cmake project as default c++ standard.This should be combined with a corresponding c++ standard used for all dune modules. But a call of target_compile_features( cxx_std_) on the target with name sets an arbitrary standard requirement for the code. Mixing c++ standards in dependent libraries is undefined behaviour, and thus not recommended. How to enforce in a downstream module a different (higher) c++-standard for a specific target than is set in dune-common?.How do downstream modules/libraries inherit the c++-standard requirement? Simply by linking against the dunecommon target.The c++-standard is not a global property / global compiler flag anymore. The dunecommon target-properties are only propagated, if a downstream target links against it. The change has an implication on other dune modules and targets. This has to be tested separately using individual feature tests. It might be, though, that not all c++-17 library feature are already implemented by the corresponding standard library. With this MR, the dunecommon library target gets the compile-feature cxx_std_17 that enforces at least c++-language standard 17 to be supported by the compiler. By using these, the highest required standard is passed to the compiler and there is not mixup with flags and standard requirements. The "cmake-way" of setting the c++-standard requirement is either a target property or a target feature. Sometimes the user needs a higher c++ standard than defined for dune-common, maybe just on a single target. ![]() ![]() DetailsĮnforcing a c++-standard is different between compilers, the flags might have different names or are not necessary at all. The cmake function dune_require_cxx_standard() is now deprecated. The cmake options CXX_MAX_STANDARD, CXX_MAX_SUPPORTED_STANDARD and DISABLE_CXX_VERSION_CHECK are removed. This requirement is propagated to all other modules by linking against dunecommon. Setting the minimal c++ standard in cmake is now done by a cmake feature-requirement cxx_std_17 on the dunecommon library target. ![]()
