c++ - 如何在ubuntu中安装SFML？

我下载了SFML，然后将其所有标头复制到usr / local / include /中，并将其所有库复制到usr / local / lib /中。

我要编译的桌面中有一个名为main.cpp的文件。

首先，我这样做：

g++ -c main.cpp

之后，当我尝试执行此操作时：-

g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system

它给了我：-

/usr/local/lib/libsfml-window.so: undefined reference to `udev_device_get_parent_with_subsystem_devtype@LIBUDEV_183'

我已经正确安装了所有这些必需的依赖项：

我错过了任何必要的步骤吗？

最佳答案

仅仅因为您已安装依赖项，并不意味着您正在使用它们。

undefined reference to `udev_device_get_action@LIBUDEV_183'

提到udev和LIBUDEV告诉我，您需要链接到libudev。尝试将-ludev添加到命令行。

如果粘贴了所有链接错误，则实际上可以解决它。如果仅粘贴了前20个，则可能需要链接其他库。查看缺少的符号，找出它们来自哪个库，然后添加它们。

/usr/local/lib/libsfml-graphics.so: undefined reference to `std::__throw_out_of_range_fmt(char const*, ...)@GLIBCXX_3.4.20'

不知道有什么交易。您可能需要链接C ++库？

无论如何，您应该查看有关为SFML项目设置makefile的说明：https://github.com/SFML/SFML/wiki/Tutorial%3A-Build-your-SFML-project-with-CMake
