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 CPP=arm-linux-androideabi-g++
export AR=arm-linux-androideabi-ar

- build & install
./configure

make install
- get sources
wget https://www.openssl.org/source/openssl-1.0.1p.tar.gz
tar -xvzf openssl-1.0.1p.tar.gz

Hello,
I'm trying to cross-compiling curl for all android archs by following your guide, but i get error at this following point:
. ./Setenv-android.sh
There is my error:
. ./Setenv-android.sh : command not found : command not found : command not found : command not found : command not found : command not found : command not found : command not found bash: ./Setenv-android.sh: line 106: syntax error near the unexpected symbol "$'do\r'". ash: ./Setenv-android.sh: line 106:do`(translated)
Of course, i have follow your step:
change _ANDROID_API="android-18" to _ANDROID_API="android-21" in Setecn
I'm targeting Android Pie (API 28) and
CPU archs.
I don't understand from what this error come from.
Any help would be very appreciated.
