set _CYGBIN=C:\cygwin\bin
The path of cygwin bin
set _ANDROIDTOOLS=D:\anroid\android-sdk-windows\tools
The path of android sdk tools
set _NDKROOT=D:\anroid\android-ndk-r5b
The root of ndk

安装目录：

C:\android-ndk-r7

C:\cocos2d-1.0.1-x-0.10.0

C:\cygwin

cygwin至少需要安装gcc和make工具，最好把vim也装起。

环境变量：

leoyangnc@leoyangnc-PC ~

$ cat env.sh

export NDK_ROOT=/cygdrive/c/android-ndk-r7

export COCOS2DX_ROOT=/cygdrive/c/cocos2d-1.0.1-x-0.10.0

alias ndk-build=/cygdrive/c/android-ndk-r7/ndk-build

leoyangnc@leoyangnc-PC /cygdrive/c/cocos2d-1.0.1-x-0.10.0/HelloWorld/android

$ cat build_native.sh

# set params

#ANDROID_NDK_ROOT=/cygdrive/d/programe/android/ndk/android-ndk-r6b

#COCOS2DX_ROOT=/cygdrive/e/cocos2d-x

ANDROID_NDK_ROOT=/cygdrive/c/android-ndk-r7

COCOS2DX_ROOT=/cygdrive/c/cocos2d-1.0.1-x-0.10.0

编译

cocos2d-x 0.10.0 android 编译后出现错误

android sdk 15，ndk 7，cocos2d-x 0.10.0。创建的项目何helloworld都出现这个错误，请教问题原因及解决方案。

解决方案

打开 cocos2dx/Android.mk
把下面这行
LOCAL_CFLAGS := -DUSE_FILE32API
改成
LOCAL_CFLAGS := -DUSE_FILE32API -DGL_GLEXT_PROTOTYPES=1

----------------------------------------------------

在使用Android NDK进行编译的时候可能会出现
Android NDK: Host 'awk' tool is outdated. Please define HOST_AWK to point to Gawk or Nawk !

解决方案

Linxu 平台：cd /cygdrive/c/android-ndk-r7/prebuilt/linux-x86/bin/awk

Windows 平台：cd /cygdrive/c/android-ndk-r7/prebuilt/windows/bin/awk

到相关目录下查看，发现真有一个awk执行文件，也就是说ndk默认自带了一个过期的awk工具，删掉它即可（为保险起见可mv重命名），重新ndk-build，成功！
