构建android项目会产生make error 2

Question

我最近购买了一本书,以帮助我开发包含一些代码示例的Android C++.但是,当我来构建一些示例代码时,我收到以下错误:

C:\ndk\android-ndk-r9\ndk-build.cmd all 
"Compile++  : Chapter10 <= Chapter10.cpp
process_begin: CreateProcess(NULL, C:/ndk/android-ndk-r9/toolchains/arm-linux-androideabi-4.7/prebuilt/windows/bin/arm-linux-androideabi-g++ -MMD -MP -MF ./obj/local/armeabi/objs/Chapter10/Chapter10.o.d -fno-exceptions -fno-rtti -Ijni -IC:/ndk/android-ndk-r9/sources/android/native_app_glue -IC:/ndk/android-ndk-r9/sources/cxx-stl/stlport/stlport -IC:/ndk/android-ndk-r9/sources/cxx-stl//gabi++/include -Ijni -DANDROID -Wa,--noexecstack -Wformat -Werror=format-security -frtti -c jni/Chapter10.cpp -o ./obj/local/armeabi/objs/Chapter10/Chapter10.o, ...) failed.

make (e=2): The system cannot find the file specified.

make: *** [obj/local/armeabi/objs/Chapter10/Chapter10.o] Error 2

make文件如下所示:

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_ARM_MODE          := arm
LOCAL_C_INCLUDES        := $(LOCAL_PATH)
LOCAL_MODULE            := Chapter10
LOCAL_SRC_FILES         := Chapter10.cpp \
                           (Other cpp Files . . . )
LOCAL_LDLIBS            := -llog -landroid -lEGL -lGLESv2 -lOpenSLES
LOCAL_STATIC_LIBRARIES  := android_native_app_glue

include $(BUILD_SHARED_LIBRARY)

$(call import-module,android/native_app_glue)

Application.mk文件如下:

APP_PLATFORM    := android-9
APP_STL         := stlport_static
NDK_TOOLCHAIN_VERSION   := 4.7

这是在Windows 7计算机上使用ADT v22.2.1和Android NDK r9编译的.

NDK安装到'C:\ndk\android-ndk-r9 \'.

Answer 1

Android NDK r9包含以下工具链:

1. 臂-Linux的androideabi-4.6
2. 臂-Linux的androideabi-4.8
3. 臂-Linux的androideabi-clang3.2
4. 臂-Linux的androideabi-clang3.3
5. LLVM-3.2
6. LLVM-3.3
7. mipsel体系-Linux的Android系统4.6
8. mipsel体系-Linux的Android系统4.8
9. mipsel体系-Linux的Android的clang3.2
10. mipsel体系-Linux的Android的clang3.3
11. x86-4.6
12. x86-4.8
13. x86的clang3.2
14. x86的clang3.3

gcc 4.7没有工具链.但是,您Application.mk包含以下行:

NDK_TOOLCHAIN_VERSION   := 4.7

这告诉NDK寻找4.7工具链.它失败了.

所以,解决问题的方法是改变NDK_TOOLCHAIN_VERSION变量4.6,4.8,clang3.2,clang3.3,或者只是clang(将使用可用的最新版本锵在NDK).
