C ++ 11 code在Eclipse中产生语义错误，无法更改构建设置 [英] c++11 code generates semantic errors in Eclipse, can't change build settings
问题描述
我在用Eclipse CDT的C ++ 11 code麻烦。在code编译罚款，但在编辑器中我看到，以C ++ 11标准库中的所有引用（比如std :: shared_ptr的和std ::时辰::毫秒）被发现服务/索引标记为错误，其中prevents被运行程序。包含文件被发现，但我认为正确的标志和宏没有得到通过对CDT的内部检查繁殖，所以没有类型或头的主要内容进行定义。我也似乎无法在项目属性来更改相应的设置。
I'm having trouble with c++11 code in Eclipse CDT. The code compiles fine, but in the editor I see that all references to c++11 standard library (such as std::shared_ptr and std::chrono::milliseconds) are flagged as errors by the discovery service / indexer, which prevents the program from being run. The include files are found, but I think the proper flags and macros aren't getting propagated through to CDT's internal checks, so none of the types or main content of the headers are defined. I also can't seem to change the appropriate settings in the project properties.
我浏览描述类似的问题和可能的解决方法，如其他职位：
I've browsed other posts describing similar issues and possible fixes, such as:
- Disable Eclipse的错误发现。 （C ++ 11误报）
- Eclipse编译成功，但仍给语义错误
- c++0x编译，但Eclipse编辑器的错误甚至-gnu ++ 0x中发现
- Eclipse CDT的C ++ 11 / C ++ 0x的支持
- Disable Eclipse's error discovery. (c++11 false positives)
- Eclipse compiles successfully but still gives semantic errors
- c++0x compiles but eclipse editor errors even with -gnu++0x discovery
- Eclipse CDT C++11/C++0x support
一些解决方案通过禁用索引掩盖了问题，或者禁用特定错误/警告，但是这是不可取的，因为我确实想发生时看到真正的错误。
Some solutions mask the problem by disabling the indexer, or by disabling specific errors/warnings, but this is not desirable as I do want to see true errors when they occur.
其他（可能更正确）的解决方案描述了如何通过适当的宏通（如,. __GXX_EXPERIMENTAL_CXX0X__），并建立标志（如-std = C ++ 11），但这里是我认为是主要问题：我在IDE无法更改这些设置。在项目 - >属性 - > C / C ++常规 - > preprocessor包括路径，宏等的条目和供应商的标签显示为灰色/禁用。同样，在项目 - >属性 - > C / C ++编译 - >设置，也有工具设置或发现任何选项卡中的一些其他职位提到
Other (and probably more correct) solutions describe how to pass through appropriate macros (e.g,. __GXX_EXPERIMENTAL_CXX0X__) and build flags (e.g., -std=c++11), but here's what I think is the main issue: I can't change these settings in the IDE. In "Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros, etc", the Entries and Providers tabs are grayed out / disabled. Similarly, in "Project -> Properties -> C/C++ Build -> Settings", there are no tabs for Tool Settings or Discovery as mentioned in some of the other posts.
一些细节：我使用开普勒建立在Ubuntu 13.10 64 20140224-0627。在code我想一起工作是Android NDK（最新版本，r9d），我已经安装了谷歌的NDK插件。编译器是gcc 4.8，并使用gnustl_static运行时库。也许使用NDK工具链/插件禁用，我需要修改设置？
Some particulars: I'm using Kepler build 20140224-0627 on Ubuntu 13.10 x64. The code I'm trying to work with is for Android NDK (latest version, r9d), and I have Google's NDK plugin installed. Compiler is gcc 4.8, and using gnustl_static runtime library. Perhaps using the NDK toolchain/plugin disables the settings that I need to modify?
任何帮助是极大AP preciated。
Any help is greatly appreciated.
推荐答案
首先，请确保您的项目正确编译。
First, make sure that your project compiles correctly.
之后，转到<大骨节病> C / C ++编译 - > <大骨节病>工具链编辑器并选择<大骨节病>当前工具链：的的Linux GCC （您可能需要关闭<大骨节病>显示兼容的工具链仅）。确保<大骨节病>当前建设者还是 Android的生成器的
After that, go to C/C++ Build->Tool Chain Editor and choose Current toolchain: Linux GCC (you may need to switch off Display compatible toolchains only). Make sure that the Current builder is still Android Builder.
现在，你可以完全访问<大骨节病> C / C ++常规 - > <大骨节病>路径和符号页，其中<大骨节病> H包括 和<大骨节病> ＃符号 标签。
Now you have full access to C/C++ General->Paths and Symbols page, with h Includes and # Symbols tabs.
在这两个选项卡，我手动添加
On these two tabs, I add manually
C:/Android/android-ndk-r9d/sources/cxx-stl/gnu-libstdc++/4.6/include
C:/Android/android-ndk-r9d/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi/include
C:/Android/android-ndk-r9d/sources/cxx-stl/gnu-libstdc++/4.6/include/backward
和
__GXX_EXPERIMENTAL_CXX0X__ = 1
也许你需要切换到的 C / C ++透视的，该项目右键单击并启动<大骨节病>首页 - > <大骨节病>重建
Maybe you need to switch to C/C++ Perspective, right-click on the project and launch Index->Rebuild.
