SFML 2.5.1 和 CodeBlocks with GCC 5.1.0 - 项目编译错误
SFML 2.5.1 and CodeBlocks with GCC 5.1.0 - project compiling errors
我已经下载了 CodeBlocks (GCC 5.1.0 TDM (SJLJ)) 的 SFML 2.5.1 包，即使遵循了 SFML 指南，我仍然无法在此 IDE 中启动我的应用程序。我尝试了多种方法，但都失败了。有人可以通过从错误日志中得出结论来给我一些关于这个问题的提示吗？谢谢。我的编译器是 GCC 5.1.0，我的代码是来自 the SFML site 的示例。
建造者：
1 个来自 SFML 包的动态库。项目构建没有错误，但是当我用午餐程序时，我收到此消息：
Cannot find the entry point of procedure
_ZNKSt7_cxx1112basic_stringlcSt11char_traitslcESalcEE12find_last_ofEPKcj

（所有库都会出现此错误 - 系统、图形和 window）。
2 个来自 SFML 包的静态库：

最初的错误很可能源自预编译二进制文件的 C++ 标准标志（可能没有 -std=c++11）和您的项目设置。
为了成功 link对抗 SFML，我建议：
- 一定要按照官方教程一步一步来，不要跳过任何东西。
- 如果您 link 静态：
- 不要忘记在项目设置中定义SFML_STATIC
- 不要忘记link所有依赖项
- 链接顺序很重要，使用 rule of thumb "X depends on Y, so X comes before Y"
- 并始终确保使用相同的编译器版本来编译 SFML 和构建您的应用程序
