Fixing Eclipse errors when using Android NDK and std::vector
提问by nkassis
I'm using eclipse to develop an android app that also uses the ndk. I vectors in my app and I've done the necessary stuff to get them by including
我正在使用 eclipse 开发一个也使用 ndk 的 android 应用程序。我在我的应用程序中使用矢量，并且我已经完成了必要的工作来获得它们，包括
APP_STL := stlport_static
APP_STL := stlport_static
In my Application.mk
在我的 Application.mk
Everything is working fine it compiles and runs but Eclipse keeps giving me errors when I use the vectors
一切正常，它可以编译和运行，但是当我使用向量时 Eclipse 不断给我错误
std::vector<int> blah
for example creates an error. If I delete the error and keep going it compiles and runs fine.
例如创建一个错误。如果我删除错误并继续运行，它会编译并运行良好。
I've added ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
我添加了 ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
In my project config under C++ General -> Paths and Symbols -> include
在我的项目配置下 C++ General -> Paths and Symbols -> include
It resolves #include <vector>fine (before I added the path above I had an error for this) but I still get errors using the vectors.
它解决得#include <vector>很好（在我添加上面的路径之前，我有一个错误）但我仍然使用向量出现错误。
How can I get eclipse to stop giving me errors for this?
我怎样才能让日食停止给我错误？
EDIT:
编辑：
example error: Symbol 'vector' could not be resolved
示例错误： Symbol 'vector' could not be resolved
EDIT 2:

I tried to add
我试着添加
using namespace std;
and then using vector blah and that causes a different error:
然后使用 vector blah 并导致不同的错误：
Invalid template arguments
无效的模板参数

I've added ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
In my project config under C++ General -> Paths and Symbols -> include
我添加了 ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
在我的项目配置下 C++ General -> Paths and Symbols -> include
Yes, that's it. I've tried to add the same with the same result. However, if you add stl_port headers
对，就是那样。我试图添加相同的结果。但是，如果您添加 stl_port 标头
${NDKROOT}/sources/cxx-stl/stlport/stlport
It will do the trick. Of course it is not necessary to change
它会解决问题。当然没必要改
APP_STL := stlport_static
as it works only in eclipse indexes. It will be usefull until you are going to use something that exists in gnu-libstdc++ and doesn't exist stl-port.
因为它仅适用于 eclipse 索引。直到您要使用 gnu-libstdc++ 中存在但不存在 stl-port 的东西之前，它会很有用。

I am suing eclipse indigo rc2.
我正在起诉 eclipse indigo rc2。
I added following line in Android.mk
我在 Android.mk 中添加了以下行
LOCAL_C_INCLUDES += ${NDKROOT}/sources/cxx-stl/stlport/stlport
and Added following line in Application.mk
并在 Application.mk 中添加了以下行
APP_STL := stlport_static
then automatically my ndk stlport path added in
然后自动添加我的 ndk stlport 路径
Properties -> C++ General -> Paths and Symbols -> include
属性 -> C++ 通用 -> 路径和符号 -> 包含
good luck! ^^
祝你好运！^^

At first, we met the same problem with map and tried to add "Paths and Symbols" as suggested, however it still wouldn't work.
起初，我们遇到了与地图相同的问题，并尝试按照建议添加“路径和符号”，但仍然无法正常工作。
Later on, instead of
后来，而不是
#include <map>
we used
我们用了
#include <stl/_map.h>
The error went away and then we switched back to include <map>. Eclipse no longer complained that "Symbol could not be resolved".
错误消失了，然后我们切换回include <map>. Eclipse 不再抱怨“符号无法解析”。
It seems eclipse has a cache and somehow it can get messed up unless you specifically tell it the right place to find the symbols.
似乎 eclipse 有一个缓存，并且以某种方式它会变得一团糟，除非你特别告诉它找到符号的正确位置。

I do not know at what stage it worked, but:
我不知道它在哪个阶段起作用，但是：
Add to Application.mk
APP_STL := gnustl_staticAdd include to Project properties->C/C++ General -> Paths and Symbols
'NDK root path'/'your directory to android platform'/arch-arm/usr/include 'NDK root path'/sources/cxx-stl/gnu-libstdc++/4.9/include 'NDK root path'/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/include/bitsTurn off all warnings errors in Project properties->C++ General->Code Analisis.
- Project properties->C++ Build-> Builder Settings -> Uncheck use default build command. Build command set empty.
- Next configure NDK Builder: Project properties-> Builders-> New-> Program and fill Name (your name build conf), Location (path to NDK root directory), Working directory (path to project dir). -> Refresh and check specific resources (your libs folder in project). -> Build Options check Specify working set of relevant resources and change 'jni' folder with your source.
添加到 Application.mk
APP_STL := gnustl_static将包含添加到项目属性->C/C++ General -> Paths and Symbols
'NDK root path'/'your directory to android platform'/arch-arm/usr/include 'NDK root path'/sources/cxx-stl/gnu-libstdc++/4.9/include 'NDK root path'/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/include/bits关闭项目属性->C++ 通用->代码分析中的所有警告错误。
- 项目属性->C++ 构建-> 构建器设置-> 取消选中使用默认构建命令。构建命令集为空。
- 接下来配置NDK Builder：Project properties->Builders->New->Program并填写Name（你的名字build conf），Location（NDK根目录的路径），Working directory（项目目录的路径）。-> 刷新并检查特定资源（项目中的 libs 文件夹）。-> 构建选项检查指定相关资源的工作集并使用您的源更改“jni”文件夹。
