Downloads

If you do not want to build it by yourself, you could download our prebuilt library from there

OpenSSL Version

This a static library compile from openssl and cURL for iOS and Android.

openssl-1.0.2c.tar.gz

openssl-1.1.0c.tar.gz

cURL Version

curl-7.47.1.tar.gz

curl-7.51.0.tar.gz

protobuf Version

protobuf.tar.gz

##Android NDK Version

android-ndk-r13b

How to build

For iOS

Copy openssl-1.1.0c.tar.gz to tools file folder and run

cd tools
sh ./build-openssl4ios.sh

Copy curl-7.51.0.tar.gz to tools file folder and run

cd tools
sh ./build-curl4ios.sh

For Android

Set ENV NDK_ROOT

cd tools
sh ./build-openssl4android.sh

You could build it with ABI like

cd tools
sh ./build-openssl4android.sh android  # for armeabi
sh ./build-openssl4android.sh android-armeabi #for armeabi-v7a
sh ./build-openssl4android.sh android64-arm64 #for arm64_v8a
sh ./build-openssl4android.sh android-x86  #for x86
sh ./build-openssl4android.sh android64  #for x86_64
sh ./build-openssl4android.sh mips  #for mips
sh ./build-openssl4android.sh mips64 #for mips64

You must build openssl first

otherwise cURL HTTPS is disable (without ssl)

OpenSSL for Android is build with libz support using dynamic link. libz is publically provided by Android system.

sh ./build-curl4android.sh

You could build it with ABI like

cd tools
sh ./build-curl4android.sh android  # for armeabi
sh ./build-curl4android.sh android-armv7 #for armeabi-v7a
sh ./build-curl4android.sh android64-arm64 #for arm64_v8a
sh ./build-curl4android.sh android-x86  #for x86
sh ./build-curl4android.sh android-x86_64  #for x86_64
sh ./build-curl4android.sh mips  #for mips
sh ./build-curl4android.sh mips64 #for mips64

How to use

For iOS

Copy lib/libcrypto.a and lib/libssl.a and lib/libcurl.a to your project.

Copy include/openssl folder and include/curl folder to your project.

Add libcrypto.a and libssl.a and libcurl.a to Frameworks group and add them to [Build Phases] ====> [Link Binary With Libraries].

Add openssl include path and curl include path to your [Build Settings] ====> [User Header Search Paths]

About "__curl_rule_01__ declared as an array with a negative size" problem

When you build cURL for arm64 you will get this error.

You need to change curlbuild.h from :

#define CURL_SIZEOF_LONG 4

to :

#ifdef __LP64__
#define CURL_SIZEOF_LONG 8
#else
#define CURL_SIZEOF_LONG 4
#endif

For Android

Copy lib/armeabi folder and lib/armeabi-v7a folder and lib/x86 to your android project libs folder.

Copy include/openssl folder and include/curl to your android project.

Android Makefile

Add openssl include path to jni/Android.mk.

#Android.mk

include $(CLEAR_VARS)

LOCAL_MODULE := curl
LOCAL_SRC_FILES := Your cURL Library Path/$(TARGET_ARCH_ABI)/libcurl.a
include $(PREBUILT_STATIC_LIBRARY)


LOCAL_C_INCLUDES := \
	$(LOCAL_PATH)/Your Openssl Include Path/openssl \
	$(LOCAL_PATH)/Your cURL Include Path/curl

LOCAL_STATIC_LIBRARIES := libcurl

LOCAL_LDLIBS := -lz
	

CMake

Define ssl, crypto, curl as STATIC IMPORTED libraries.

add_library(crypto STATIC IMPORTED)
set_target_properties(crypto
  PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/libs/${ANDROID_ABI}/libcrypto.a)

add_library(ssl STATIC IMPORTED)
set_target_properties(ssl
  PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/libs/${ANDROID_ABI}/libssl.a)

add_library(curl STATIC IMPORTED)
set_target_properties(curl
  PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/libs/${ANDROID_ABI}/libcurl.a)

Then link these libraries with your target, e.g.

target_link_libraries( # Specifies the target library.
                       native-lib

                       curl
                       ssl
                       crypto
                       )
