这个错误意味着什么以及如何解决它？
我正在尝试在 android 中使用 NDK 构建 C++ 代码。我有一个方法，它有一个参数 vector <;向量
一切都构建得很好，直到我在方法
vector
我开始收到此错误，
D:/eclipseworkspace/myLibProject/obj/local/armeabi/libmyLibProject.a(FileName.o): In function `std::priv::_Vector_base<std::vector<float, std::allocator<float> >, std::allocator<std::vector<float, std::allocator<float> > > >::_M_throw_out_of_range() const':
D:/androidndk/sources/cxx-stl/stlport/stlport/stl/_vector.c:45: undefined reference to `std::__stl_throw_out_of_range(char const*)'
collect2: ld returned 1 exit status
make: *** [/cygdrive/d/eclipseworkspace/myLibProject/obj/local/armeabi/libOutputName.so] Error 1
我不知道为什么会发生这种情况，Google 也没有提供帮助。
谢谢。
I am trying to build a C++ code using NDK in android. I have a method which has a parameter vector < vector <float> > coordinates
Everything builds fine until I write this line inside my method
vector<float> firstPoint = coordinates.at(0);
I start getting this error
D:/eclipseworkspace/myLibProject/obj/local/armeabi/libmyLibProject.a(FileName.o): In function `std::priv::_Vector_base<std::vector<float, std::allocator<float> >, std::allocator<std::vector<float, std::allocator<float> > > >::_M_throw_out_of_range() const':

collect2: ld returned 1 exit status
make: *** [/cygdrive/d/eclipseworkspace/myLibProject/obj/local/armeabi/libOutputName.so] Error 1
I have no clue why this is happening and Google is not helping either.
Thanks.

我认为您在同一项目中使用标准库的两种不同实现。
看起来您正在使用 D:/android... 中标准库的 stlport 实现（的标头）来编译文件，并且链接到本地库。
您必须在 ide （或 Makefile）中配置链接器才能使用相同实现的 lib 文件（在 D:/android 中的某个位置...我猜）。
I think you are using two different implementation of the standard library in the same project.
It looks like you are compiling your files with (the headers of) an stlport implementation of the standard library in D:/android..., and you link against your local library.
You have to configure the linker in your ide (or Makefile) to use also the lib file of the same implementation (somewhere in D:/android... I guess).
这是一个链接错误。您需要将
APP_STL := stlport_static添加到您的Apllication.mk文件中。另请确保使用-fno-exceptions标志，因为 STLport 与 C++ 异常和 RTTI 不兼容。您可以在
APPLICATION-MK.HTML< 中获取更多信息/a> 可在 NDK 的docs文件夹中找到。CPLUSPLUS-SUPPORT.HTML也值得一读。This is a linking error. You need to add
APP_STL := stlport_staticto yourApllication.mkfile. Also make sure that you use-fno-exceptionsflag, since STLport is not compatible with C++ exceptions and RTTI.You can get more info in
APPLICATION-MK.HTMLwhich is availavle in thedocsfolder of the NDK.CPLUSPLUS-SUPPORT.HTMLis also worth to read.这看起来像是链接器错误。您可能忘记将 STL 库引用添加到您的构建中。或者找不到
this looks like a linker error. You probably forgot to add STL library reference to your build. Or it can't be found
你这样做了吗？
Did you do this ?
当我更改
为
它时，它开始编译......：sy？
When I changed
to
it started compiling..... :s y?
