问题 I'm compiling my C++ code using clang++ that comes with ndk21. I've set both compiler flags -fno-unwind-tables and -fno-asynchronous-unwind-tables but the number of entries in the unwind table do not reduce. I also checked by setting the opposite -funwind-tables and -fasynchronous-unwind-tables but it doesn't increase either. setting -fno-exceptions does reduce the number of entries slightly which makes me think I'm passing the flags correctly. Does anyone have any idea why this could be the

问题 I am using CMake for building my projects on Windows (Visual Studio) as well as on Linux machines(gcc). I'd like to mark some code as "debugging only", like with #ifdef DEBUG //some logging here #endif The question is: what compiler definition is available on all platforms in the CMake "Debug" build type? DEBUG seems not to exist. (I want to have the logging or whatever only when the build type is Debug.) 回答1: CMake adds -DNDEBUG to the CMAKE_C_FLAGS_{RELEASE, MINSIZEREL} by default. So, you

问题 Following this post, where I have used these instructions to install NVIDIA's OpenCL SDK. The clinfo tool detects a 1.2 OpenCL version correctly. However, The below CMakeLists.txt file: cmake_minimum_required(VERSION 3.1) project(OpenCL_Example) find_package(OpenCL REQUIRED) include_directories(${OpenCL_INCLUDE_DIRS}) link_directories(${OpenCL_LIBRARY}) add_executable(main main.c) target_include_directories(main PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}) target_link_libraries(main ${OpenCL_LIBRARY})

问题 Following this issue, I'm trying to compile the clifo tool using the MSVC toolchain. I use this CMakeLists.txt file which successfully finds NVIDIA's OpenCL SDK: Found OpenCL: C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v3.2/lib/Win32/OpenCL.lib (found version "1.1") However when compiling with cmake --build . I get many errors, from which the first one is: c:\path\to\clinfo\src\info_ret.h(43): error C2061: syntax error: identifier 'cl_device_affinity_domain' [C:\path\to\clinfo\build

问题 I have some C++ source code that, for a valid reason, does not end in ".cpp" or ".cc" or any other usual C++ extension. I would like to compile this into an executable with CMake. My very simple CMake script currently is: CMAKE_MINIMUM_REQUIRED(VERSION 2.8) PROJECT(test) SET_SOURCE_FILES_PROPERTIES(test_mycode.foo PROPERTIES LANGUAGE CXX) ADD_EXECUTABLE(test test_mycode.foo) As far as I understand, SET_SOURCE_FILES_PROPERTIES(...) should be all that is needed to make Cmake recognize "test

问题 Now, I implemented a factory class to dynamically create class with a idenification string, please see the following code: void IOFactory::registerIO() { Register("NDAM9020", []() -> IOBase * { return new NDAM9020(); }); Register("BK5120", []() -> IOBase * { return new BK5120(); }); } std::unique_ptr<IOBase> IOFactory::createIO(std::string ioDeviceName) { std::unique_ptr<IOBase> io = createObject(ioDeviceName); return io; } So we can create the IO class with the registered name: IOFactory

问题 Is there a way to compare files using cmake? I've checked all parameters from https://cmake.org/cmake/help/latest/command/file.html 回答1: cmake executable has a tool mode, when it performs some useful actions instead of project's configuration. And compare_files is one of the commands for that mode. For get features of the CMake command line tool mode in the CMakeLists.txt , use execute_process command: execute_process( COMMAND ${CMAKE_COMMAND} -E compare_files <file1> <file2> RESULT_VARIABLE

问题 I'm having troubles with linking freetype 2 under linux using cmake when building a C++11 project with an extern C library. With cmake and freetype 2 I basically have 2 options : use the utility freetype-config like freetype-config --libs use the FindFreetype cmake module Now I'm trying to implement the second option and I'm not very skilled with cmake nor I understand the logic of it. My problem is the linking phase, I have no idea how to do that properly plus this module is not as complete
