3 Cygwin environmental validation

① Run Cygwin once (Cygwin.bat) to create some user environment files
② Detection

GCC version: GCC--version
Version of g++: g++--version
Make version: Make--version
GDB version: GdB--version

4 Configuring the NDK Path

① Extract the downloaded NDK to a directory
② Zai Cygwin home\< Your user name >\.bash_profile file last added: (Available notepad++ or ultraedit open)
ndk=/cygdrive/< your drive symbol >/<android NDK directory > Export NDK,
As my NDK=/CYGDRIVE/C/ANDROID/ANDROID-NDK-R7 export NDK
Note: The name "NDK" is a casual, often used not too long
② Verification
Restart Cygwin, input: cd $NDK
You can enter the NDK corresponding directory description settings OK.

5 compiling a project to generate a. so file

Way One:
Compile under the Cygwin command line, as shown in the three-step process

① into Android Project working directory: CD $NDK
② into the Samples\hello-jni directory, the full path is C:\Android\android-ndk-r7\samples\hello-jni
③ run: $NDK/ndk-build.
Note: the command $NDK and/ndk-build are connected together, there is no space in the middle, the actual use is to break into the full $ndk/ndk-build, do not just play ndk-build

Way two:
① in the. bash_profile file that is mentioned in step 4, add the Jni=/cygdrive/jni directory
As I can for Jni=/cygdrive/c/android/android-ndk-r7/samples/hello-jni
② CD $NDK
③ CD $jni

Generate two files after compiling compiled normally, for example, generate the corresponding. So file in the project Libs/armeabi directory.
