我在 native 应用程序中链接 STL 时遇到一些问题。 map::operator[] 和 map::insert 的链接失败，而其他 map 函数的链接成功。 我的 Application.mk 是:

APP_STL := gnustl_static
APP_CPPFLAGS := -fexceptions -frtti
APP_CPPFLAGS += -g3
APP_CPPFLAGS += -DDEBUG
APP_ABI := armeabi-v7a
APP_PLATFORM:=android-14
NDK_TOOLCHAIN_VERSION:=4.6

native 代码包含两个文件夹级别。我为每个内部文件夹创建了一个 Android.mk 文件来编译生成静态库。我在最深的文件夹中使用 std::map 。 Android.mk 看起来像:

TEMP_PATH_REG := $(call my-dir)
LOCAL_PATH := $(TEMP_PATH_REG)
include $(call all-subdir-makefiles)
LOCAL_PATH := $(TEMP_PATH_REG)
include $(CLEAR_VARS)

LOCAL_MODULE            := registration
LOCAL_C_INCLUDES     := $(LOCAL_PATH)/../glm/
LOCAL_SRC_FILES        := registration_factory.cpp \
                                          inertial.cpp                                       
LOCAL_LDLIBS               := -llog -landroid -lEGL
LOCAL_STATIC_LIBRARIES     := android_native_app_glue
include $(BUILD_STATIC_LIBRARY)
$(call import-module,android/native_app_glue)

当我构建项目时，出现以下错误:

我做错了什么？

非常感谢。

最佳答案

我找到了编译项目的解决方法。

LOCAL_LDLIBS += ~/.android-ndk-r8c/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/libsupc++.a
LOCAL_LDLIBS += ~/.android-ndk-r8c/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/libgnustl_static.a
