Libcurl requires openssl and zlib to be fully operationnal
- Step 1 : cross compile zlib
- Step 2 : cross compile openssl
- Step 3 : cross compile curl with zlib/openssl external link
Prerequisites :
- NDK installed
- NDK added to PATH :
PATH=$PATH:/home/user/android-ndk - standalone toolchain generated and added to path :
PATH=$PATH:/home/user/android-toolchain/bin
- get sources
wget http://zlib.net/zlib-1.2.8.tar.gz
tar -xvzf zlib-1.2.8.tar.gz
cd zlib-1.2.8
- build settings
INSTALLATION_PATH=/path/to/install_directory
export CC=arm-linux-androideabi-gcc
export CPP=arm-linux-androideabi-g++
export AR=arm-linux-androideabi-ar
export prefix=$INSTALLATION_PATH
- build & install
./configure
make
make install
- get sources
wget https://www.openssl.org/source/openssl-1.0.1p.tar.gz
tar -xvzf openssl-1.0.1p.tar.gz
- build settings
#Delete all reference to arm-linux-androideabi arch in your path before pursuing, the following will do this for you

wget https://wiki.openssl.org/images/7/70/Setenv-android.sh
chmod 777 Setenv-android.sh
export ANDROID_NDK_ROOT=/path/to/ndk
change _ANDROID_API="android-18" to _ANDROID_API="android-21" in Setecn

cd openssl-1.0.1p

@xerta555 Seems to be some problem with the line endings.
Running
dos2unix Setenv-android.shshould do the trick.
