I am new to docker. I installed docker and I built the docker file. I can see the image in my repo (android/curl latest f4b6bd643336). How do I use the static lib? Is it only available within docker container?

RUN curl -O https://www.openssl.org/source/openssl-1.0.2.tar.gz &&
tar -xzf openssl-1.0.2.tar.gz &&
mv openssl-1.0.2 openssl

copy libssl.so /openssl
copy libcrypto.so /openssl
#Build SSL section ends

And then added –with-ssl=/Android/openssl in ./configure but the compiled libcurl does not seem to link libssl as size of libcurl.a don’t change & also ssl functionality doesn’t work.

Am I missing something?

We got that every Android OS has libssl and libcrypto libraries that are part of OpenSSL, but not included in NDK for using them. You can pull them via below command:

$adb pull /system/lib/libssl.so /myndk/platforms/android-19/arch-arm/usr/lib

$adb pull /system/lib/libcrypto.so /myndk/platforms/android-19/arch-arm/usr/lib

We are able to pull these arm based libssl.so & libcrypto.so modules.
Now the question is how can we get them into docker image so that we can use it for libcurl build?

Thanks

I have sent latest docker file in email.

And added “–with-ssl=/Android/openssl” option to ./configure.

But I keep getting following error inspite of some trials of changing few variables.
Can’t seem to understand why it keeps complaining about line option ‘-m64’. Any idea?
