Cmake c 175/5/2023 ![]() ![]() ![]() PS: I’ve used CMake 3.7.1, but also tried CMake 3.17.3, and this behavior occurs with both versions. Changes made since CMake 3.17.1: Alexander Grund (3): BoostScanDeps: Fix typo in numpy handling FindBoost: Simplify BoostVERSIONSTRING comparisons FindBoost: Add support for Boost 1.73 Alexandru Croitor (1): iOS: Fix detection of supported SDK architectures Ben Boeckel (2): FindPython: avoid autoderef in version comparisons FindPython. But I think it somewhat makes the set(CMAKE_CXX_STANDARD 14) line useless if I also have to explicitly specify all the features I expect from C 14 standard? Create an xmake project with: setlanguages('c 17') Create a CMakeLists.txt project file with xmake: xmake project -k cmake The resulting CMakeLists.txt does not have the language standard set for the target, eg: targetcompilefeatures. I’ve noticed that I can explicitly require this particular C feature by adding the line target_compile_features(Tutorial PRIVATE cxx_digit_separators). How can I get CMake to require a C 14 compatible compiler version instead? I have the DevToolSet7 compiler installed (G 7.3.1) alongside, and I want to make sure that CMake throws an error if I accidentally use the old system compiler instead. oe meta-oePATCH 10/17 paho-mqtt-cpp: Use CMAKEINSTALLLIBDIR in cmake. And then at compile time g will throw an error because it does not support that digit separator syntax. This repository contains the source code for the Eclipse Paho MQTT C. Set(CMAKE_CXX_EXTENSIONS FALSE) # just to get c 1y instead of gnu 1y - it doesn't affect the actual problemĬMake does not throw any error when using this file with G 4.8.5 it simply call g with -std=c 1y option. I’ve used these lines in my CMakeLists.txt file: set(CMAKE_CXX_STANDARD 14) But that feature is part of C 14 standard. For example, using digit separator like int oneMillion = 1'000'000 is not supported by G 4.8.5 in any mode. Support is highly experimental, and will almost certainly change in incompatible ways in future releases.”.īut -std=c 1y does not enable full C 14 support with this compiler. It may be used to specify a path on the host to. The CMAKESYSROOT is optional, and may be specified if a sysroot is available. The CMAKESYSTEMPROCESSOR is the CMake-identifier of the target architecture to build for. It provides the -std=c 11 option for C 11 support, and the -std=c 1y option for “ The next revision of the ISO C standard, tentatively planned for 2017. The CMAKESYSTEMNAME is the CMake-identifier of the target platform to build for. My target platform (RHEL 7) ships with G 4.8.5, which does not support C 14 completely. The CMake build helper will set the CONANCMAKECXXSTANDARD and. ![]() We emphasize libraries that work well with the C Standard Library. So should I upgrade to MSVC 2019 in order to get C 17 support?Ĭould anybody yet compile Netgen 6.2.x on Windows? I found this thread: but cannot find there a conclusion nor if it is really the issue I am facing.I’m just getting started with CMake and have come upon a corner case related to C 14 support with older compilers. Boost provides free peer-reviewed portable C source libraries. It has its own markup language that will translate the CMake code into the respective build language. Though, it can be used in many other languages such as Latex for instance, and many more. I see here that some C 17 seem only to be supported by MSVC 2019. CMake Cross Make is a build tool for building software, commonly for C/C . Can it be that they are only available for the enterprise version? Ubuntu 16.04 ships with CMake 3.5, and thats a a fairly reasonable lower bar for us to set our min requirements to. I found some info how to eanble c 17 in MSVC:īut the options and menus described there don't exist on my MSVC 2017 (Community edition, version 15.9). CMake 3.1.3 is definitely old enough to make a minimum requirement.
