The following issue has been SUBMITTED. ====================================================================== https://public.kitware.com/Bug/view.php?id=15906 ====================================================================== Reported By: Jan Henke Assigned To: ====================================================================== Project: CMake Issue ID: 15906 Category: CMake Reproducibility: always Severity: major Priority: normal Status: new ====================================================================== Date Submitted: 2016-01-09 12:37 EST Last Modified: 2016-01-09 12:37 EST ====================================================================== Summary: With Microsoft Visual Studio CMake should use the C++ compiler for C files, if C standard >= C99 is set Description: The Mircosoft Visual Studio C compiler only supports ISO 9899:1989 (aka C89). Newer C features are only implemented in the C++ compiler and only for the subset of C, which is part of the C++ standard (see for reference: http://herbsutter.com/2012/05/03/reader-qa-what-about-vc-and-c99/)
Since a few versions CMake provides a way to specify the features or standard for your application. Thus if the requested standard level is C99 or above, or any of the features introduced in C99 or above, CMake should use the C++ compiler for C files. To quote from above web site: "We recommend that C developers use the C++ compiler to compile C code (using /TP if the file is named something.c). This is the best choice for using Visual C++ to compile C code." Please change the generator for Visual Studio solutions accordingly. That way we can use modern C feature with CMake and the Visual Studio compilers. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2016-01-09 12:37 Jan Henke New Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
