我最近安装了(最新版本的)'Eclipse IDE for C/C++ Developers'和minGW(4.8.1),以帮助我在很长一段时间后重新使用C++.
我已经加入-std=c++11
到Other flags
在C/C++ Build/Settings/Tool Settings/GCC C++ Compiler/Miscellaneous
我有一个小程序,利用了许多C++ 11特性(例如使用chrono
库.emplace_back
).
运行后,我在Problems窗口中遇到多个未解决的问题,如下面的粘贴).
有趣的是,该程序确实编译并运行正常.
有了这个,我有没有在Eclipse中设置解决这些问题的东西?
有没有人知道to_string()
minGW(4.8.1)中的函数是否仍有问题,例如以下内容无法编译:
window.setTitle("Bullets on screen: " + to_string(bullets.size()) + " currentSlice: " + to_string(currentSlice) + " FT: " + to_string(ft) + " FPS: " + to_string(fps) );
它使用Visual Studio Express 2013进行编译(尽管它存在chrono
库的准确性问题,因此切换到minGW).
谢谢.

转到Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros, etc. -> Providers -> CDT GCC built-in compiler settings
,取消激活Use global provider shared between projects
并添加命令行参数-std=c++11
.
eclipse实时代码分析与构建编译器不共享相同的设置.您还可以在全局(不仅仅是项目)中更改设置Window -> Preferences -> C/C++ -> Build -> Settings -> CDT GCC Built-in Compiler Settings
.
编辑:您需要#include
使用std::to_string
.
我在@Nabla和@Enissey给出的答案中添加了一些细节.
添加命令行参数时,例如,全局首选项中的CDT GCC内置编译器设置Cygwin,
${COMMAND} ${FLAGS} -E -P -v -dD "${INPUTS}"
这样做,
${COMMAND} ${FLAGS} -E -P -v -dD -std=c++11 "${INPUTS}"
要重建索引,请右键单击项目,转到Index子菜单,然后选择"Rebuild".
就我而言,我在全局范围内进行了更改并重建了索引.
