NDK 使用筆記

=======[環境相關] 配置NDK環境變量問題？


D:\Program Files\cygwin\home\aa目錄下的.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 這個目錄只保留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.如果需要直接指定項目目錄編譯命令：
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

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
