未定义对(SFML)的引用 [英] Undefined reference to (SFML)

问题描述

我正在尝试将SFML与CMake链接，但是make存在一些问题:

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&)'

还有诸如此类的错误.

首先，我通过以下命令安装了SFML:

First of all, I installed SFML by this command:

sudo apt-get install libsfml-dev

然后按照本教程进行操作:

And then followed this tutorial :

https://github.com/SFML/SFML/wiki/Tutorial:-Build-your-SFML-project-with-CMake

我认为链接存在问题，但我不知道如何解决.

I think this is a problem with linking, but I don't know how to fix it.

我的链接顺序是:

find_package(SFML 2 REQUIRED graphics window main system)

推荐答案

find_package 不执行任何链接，您需要使用 target_link_libraries ，如您所看到的链接所示发表自己:

find_package does not perform any linking, you need to use target_link_libraries as seen in the link that you posted yourself:

target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})
