cmake

问题 I have set up cross-platform software project using CMake Superbuild, where dependencies are added and built using ExternalProject_Add . The project compiles on both Windows and Linux, but when I try to run the executable programs that are produced, it does not work because it fails to find dll/so files of dependencies. This is not surprising, as the dll/so files of external dependencies are not placed in the output directory( bin in visualization below). One of the dependencies that are

问题 I am trying to learn how to use gtest for creating unit testing in c++. I wrote a simple library to test, where I created a factorial function src/main.cpp #include <iostream> int factorial(int n) { if (n == 1) return 1; return n * factorial(n - 1); } // Default main function int main() { std::cout << "Hello, World!" << std::endl; return 0; } src/main.h #ifndef GTEST_LEARN_MAIN_H #define GTEST_LEARN_MAIN_H int factorial(int n); #endif //GTEST_LEARN_MAIN_H src/CMakeLists.txt add_executable

问题 This question follows my precedent one. I'm writing a C++ program with OpenCV, Torch and NumCpp. The program compiles and works fine for now, but I need to write unit tests. I've followed google's tutorial to build GTest and GMock inside my project, but it fails. When I don't link Torch libraries, that works. Error when linking GTest + Torch : /usr/bin/ld: CMakeFiles/TryGTest_test.dir/test/boxTest.cpp.o: in function `testing::AssertionResult testing::internal::CmpHelperEQFailure<int, int>

问题 I'm trying to build basic GTK+ code(one of its tutorials) with CMake, but I keep getting 'undefined reference to *' where * is any GTK function that is in the code. I tried to look after guides/tutorials on this, but most of them are mostly similar to what I have. Regular compilation from terminal works without a problem using command: g++ ./test.cpp -o test `pkg-config --cflags --libs gtk+-3.0` When I try using CMake my CMakeLists.txt is: cmake_minimum_required(VERSION 3.0.2) project(gtktest

问题 (During writing this question I found a solution, so this just documents it, because I would really have needed it beforehand!) Im writing a c++ project and use cmake for it. In my cmake file I have: set(MY_DEBUG_WARNINGS "-Og -Wall" ) # Add warnings: add_compile_options("$<$<CONFIG:DEBUG>:${MY_DEBUG_WARNINGS}>" "$<$<CXX_COMPILER_ID:Clang,AppleClang>:-fcolor-diagnostics>" "$<$<CXX_COMPILER_ID:GNU>:-fdiagnostics-color>" ) which doesn't work, because the compile command picks up extra escaped

问题 Running IDE-Machine Windows 10 with Visual Studio 2019. Target-System for debugging is a Ubuntu 18.04. Using CMake available in Visual Stdio addons. Test software is the soem lib, with the simple_test programm, wich already leads to the issue (https://github.com/OpenEtherCATsociety/SOEM). After passing the eth-interface to the built programm, it stops with cause it can't get root. Already tried to pass sudo in the launch.vs.json and also pipe sudo the programm. Tried to change the access to

问题 I'm getting undefined reference to dlsym@@GLIBC_2.2.5 even after linking it before and after the libraries. However in the linking output it appears that it's linking just before, but linking before all libraries should work, I guess. /bin/g++-9 CMakeFiles/http_downloader.dir/http_downloader_cli.cpp.o CMakeFiles/http_downloader.dir/SimpleOpenVPNSocket.cpp.o -o http_downloader -lpthread /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/x86_64-linux-gnu/liblz4.so -ldl downloader/libhttp_downloader

问题 I am trying to link SFML with CMake, but I have some issues with make: /home/ishidex2/Documents/QtCreator/CMakeExample/main.cpp:-1: error: undefined reference to `sf::String::String(char const*, std::locale const&)' And some kind of errors like this. First of all, I installed SFML by this command: sudo apt-get install libsfml-dev And then followed this tutorial : https://github.com/SFML/SFML/wiki/Tutorial:-Build-your-SFML-project-with-CMake I think this is a problem with linking, but I don't

问题 I have installed opencv, qt, qt creator, cmake on ubuntu 15.10 through VMware on windows.
