build openssl for android

[Indtiny s]

Hi,

I have to build the openssl 1.0.1c for the android , I have added new  ECC-CCM chiper key support at the openssl , hence i want build the same for android-ndk and use in my application as shared libraries . is there any guide to build the same ..?

For Android, check out this project as an example:

https://github.com/eighthave/openssl-android

They have the Android-specific Makefile configs for doing an NDK build.  You could patch it with your changes and generate the .so libraries you need.

Do not use that one, it's old. Use this one  https://github.com/aluvalassuman/OpenSSL1.0.1cForAndroid 

Just calling ndk-build should work.

Oh, and I highly suggest specifying the TARGET_ABI so that the code is optimized(considerable boost compared to without specifying it).

So either add TARGET_ABI := android-APILEVEL-armeabi to android-config.mk OR open Android.mk in the crypto and ssl folders, and add it just before $(BUILD_SHARED_LIBRARY).

Be sure to replace APILEVEL with the API level you target. And if you want static libraries, replace  $(BUILD_SHARED_LIBRARY)  where encountered to  $(BUILD_STATIC_LIBRARY)

Hi,

My android for the TAB is HoneyComb and its API level is 12 so I have wriiten it as

TARGET_ABI:=android-12-armeabi

 

I put the above line in android-config.mk just below the first LOCAL_CFLAGS and excuted the ndk-build but I got the following error .

 

linux-androideabi/bin/ld: warning: libz.so, needed by ./obj/local/armeabi/libcry

./obj/local/armeabi/libcrypto.so: undefined reference to `zError'
./obj/local/armeabi/libcrypto.so: undefined reference to `inflateEnd'
./obj/local/armeabi/libcrypto.so: undefined reference to `deflate'
./obj/local/armeabi/libcrypto.so: undefined reference to `deflateInit_'

I don't at this point own an android and I am thinking of getting one. I'd like to ask of the environment. Will I need to root it? I expect the answer is yes and I'll have to install all the development tools as well. Its there a website which provides instructions.

Next what of cross compilers or a development environment which runs on say the desktop and provides the test bed that the phone uses.

THanks.

Hi,

When I complied  my old code (openssl-android 1.0.0e)  which downloaded from the github , ir built properly ..

but this new code from the  https://github.com/aluvalassuman/OpenSSL1.0.1cForAndroid
is throwing the zlib not found error .. I ran everything through $ sudo ndk-build script only .

 

Is there any reference needs to be added in the android.mk for the new code ..?

[Indtiny s]

Hi,
adding more to my previous problem reference post :

That library is there in the ndk floder

/home/indu/Android/android-ndk-r8b/platforms/android-9/arch-x86/usr/lib/libz.a
/home/indu/Android/android-ndk-r8b/platforms/android-9/arch-x86/usr/lib/libz.so
/home/indu/Android/android-ndk-r8b//platforms/android-9/arch-arm/usr/lib/libz.so
/home/indu/Android/android-ndk-r8b//platforms/android-4/arch-arm/usr/lib/libz.so
/home/indu/Android/android-ndk-r8b//platforms/android-8/arch-arm/usr/lib/libz.so
/home/indu/Android/android-ndk-r8b//platforms/android-5/arch-arm/usr/lib/libz.so
/home/indu/Android/android-ndk-r8b//platforms/android-3/arch-arm/usr/lib/libz.so


But I'm getting the following error when with ndk-build

/home/indu/Android/android-ndk-r8b/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.6.x-google/../../../../arm-linux-androideabi/bin/ld: warning: libz.so, needed by ./obj/local/armeabi/libcrypto.so, not found (try using -rpath or -rpath-link)

Dear Indu,

I have the exact same problem/error of the libz.

How did you solve it? Can anybody share your method? Thanks a ton,

-Tera
