NDK 使用笔记

=======[环境相关] 配置NDK环境变量问题？

D:\Program Files\cygwin\home\aa目录下的.bash_profile中末尾添加：

NDK=/cygdrive/d/android-ndk-work-folder/android-ndk-r7b

PATH=$PATH:$NDK

另外：

R7 :

android-ndk-r7b\platforms 这个目录只保留android-14

r10 的改：

android-ndk-r10c\toolchains\

arm-linux-androideabi-4.6你把這個目錄刪掉，然後把arm-linux-androideabi-4.9改成arm-linux-androideabi-4.6吧

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

2.如果需要直接指定项目目录编译命令：

andy@-PC cd /cygdrive/d/android-ndk-work-folder/android-ndk-r4b-windows/android-ndk-r4b

$ ./ndk-build -C ../../../Android_project/GC_Project/kernel/ MY_TARGET_DEVICE=237

Administrator@-pc027 /cygdrive/d

$ cd -

/cygdrive/d/android-ndk-r4b-windows

Administrator@pc027 /cygdrive/d/android-ndk-r4b-windows

$ pwd

/cygdrive/d/android-ndk-r4b-windows

Administrator@-pc027 /cygdrive/d/android-ndk-r4b-windows

$ ./build/prebuilt/windows/arm-eabi-4.2.1/bin/arm-eabi-addr2line.exe -f -e ./

Administrator@-pc027 /cygdrive/d/android-ndk-r4b-windows/android-ndk-r4b

$ ls -a

以下為r7b上的定位查找命令：

../../toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-addr2line.exe -f -e ./obj/local/armeabi/libmstarcodec.so 0x04308

如果絕對路徑不行可以嘗試：

@-PC /cygdrive/d/Android_project/project/obj/local/armeabi

$ addr2line.exe -f -e ./libnativeplatformso_ics.so
