Can'；t在将Android/NDK项目转换为c+之后，使用CDT在Eclipse中构建它+；项目

我尝试构建项目示例。这是一个Android+NDK项目。当我通过shell使用NDK构建时，它工作得很好，但是后来我使用Eclipse CDT将项目转换为C++项目。现在我无法在Eclipse中构建它：

**** Build of configuration Default for project ImageTargets ****

make all 
make: *** No rule to make target `all'.  Stop.

**** Build Finished ****

这里是Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := QCAR-prebuilt
LOCAL_SRC_FILES = ../../../build/lib/$(TARGET_ARCH_ABI)/libQCAR.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../build/include
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := ImageTargets

TARGET_PLATFORM := android-5

USE_OPENGL_ES_1_1 := false

ifeq ($(USE_OPENGL_ES_1_1), true)
    OPENGLES_LIB  := -lGLESv1_CM
    OPENGLES_DEF  := -DUSE_OPENGL_ES_1_1
else
    OPENGLES_LIB  := -lGLESv2
    OPENGLES_DEF  := -DUSE_OPENGL_ES_2_0
endif

LOCAL_CFLAGS := -Wno-write-strings $(OPENGLES_DEF)
LOCAL_LDLIBS := \
    -llog $(OPENGLES_LIB)
LOCAL_SHARED_LIBRARIES := QCAR-prebuilt
LOCAL_SRC_FILES := ImageTargets.cpp SampleUtils.cpp Texture.cpp
LOCAL_ARM_MODE := arm
include $(BUILD_SHARED_LIBRARY)

我试图创建自定义生成器，但没有任何帮助。 建筑商名单：

环境：

视窗7 32

GNU Make 3.82.90

g++3.4.4

android ndk r6

谢谢你的帮助。谢谢。

我记得我试过fastcv样本，并描述了该技术的工作原理。所以我浏览了一下，在项目的根目录中找到了另一个makefile。我已经将它添加到QCAR样本中，现在它似乎可以工作了。 我不熟悉makefile，但我认为关键在于将“all”定义为“ndk build”：

#
# Determine host system and architecture from the environment
# (Borrowed from NDK makefile "init.mk"
#

HOST_OS := $(strip $(HOST_OS))
ifndef HOST_OS
    # On all modern variants of Windows (including Cygwin and Wine)
    # the OS environment variable is defined to 'Windows_NT'
    #
    # The value of PROCESSOR_ARCHITECTURE will be x86 or AMD64
    #
    ifeq ($(OS),Windows_NT)
        HOST_OS := windows
    else
        # For other systems, use the `uname` output
        UNAME := $(shell uname -s)
        ifneq (,$(findstring Linux,$(UNAME)))
            HOST_OS := linux
        endif
        ifneq (,$(findstring Darwin,$(UNAME)))
            HOST_OS := darwin
        endif
        # We should not be there, but just in case !
        ifneq (,$(findstring CYGWIN,$(UNAME)))
            HOST_OS := windows
        endif
        ifeq ($(HOST_OS),)
            $(error Unable to determine HOST_OS from uname -s: $(UNAME))
            $(error Please define HOST_OS in your environment.)
        endif
    endif
    $(info Host OS was auto-detected: $(HOST_OS))
else
    $(info Host OS from environment: $(HOST_OS))
endif

#
# Define function to fix path names to work with Make
#
ifeq ($(HOST_OS),windows)
    fixpath = $(shell cygpath $(subst \,/,$(1)))
else
    fixpath = $(1)
endif

# Fix working directory path for NDK tools
PWD := $(call fixpath,$(PWD))

# Fix Android NDK root path
ANDROID_NDK_ROOT := $(call fixpath,$(ANDROID_NDK_ROOT))

all:
    @$(ANDROID_NDK_ROOT)ndk-build 

clean:
    @$(ANDROID_NDK_ROOT)ndk-build clean

转到窗口->首选项->Android->NDK

“NDK位置”文本框添加NDK（Windows版本）的路径（例如，C:\ANDROID-NDK-R6）

这不是C++项目，它是Android项目。删除CDT Builder并启用本地的一个。转换为C++项目并不使它成为“纯C++项目”，它只添加了诸如C++代码辅助和本地和Android构建的特性。后者是我的目标。
