How to build

!!!Scripts are compiled and passed on the Mac, not tested on the Linux system

  • MacOS info: 10.15.2

For iOS

  • Xcode info: Version 11.3.1 (11C504) (for reference only)
  • Build dependencies: todo
  • Build order: 1.build openssl, 2.build nghttp2, 3.build curl (curl depend openssl and nghttp2)
  • only build static library(.a)
  • build sh cmd: for example:
$ cd tools
$ sh build-ios-openssl.sh
$ sh build-ios-nghttp2.sh
$ sh build-ios-curl.sh

For Android

  • Android Studio info: 3.5.3 (for reference only)
  • Build dependencies: todo
  • Build order: 1.build openssl, 2.build nghttp2, 3.build curl (curl depend openssl and nghttp2)
  • build static library(.a) and dynamic library (exclude curl arm64-v8a)
  • env macro: for example:
export ANDROID_HOME=/Users/userid/Library/Android/sdk
export ANDROID_NDK_ROOT=$ANDROID_HOME/ndk-bundle

  • build sh cmd: for example:
$ cd tools
$ sh build-android-openssl.sh
$ sh build-android-nghttp2.sh
$ sh build-android-curl.sh

You must build openssl and nghttp2(support http2) first

Others

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

Demo

iOS

  • Xcode version 11.3.1
  • The latest available example is in the demo2 folder (/openssl_for_ios_and_android/example/ios/demo2).
  • Copy libcrypto-universal.a, libcurl-universal.a, libnghttp2-universal.a, libssl-universal.a four files to folder (/openssl_for_ios_and_android/example/ios/demo2/test_curl_with_ssl_and_http2_ios/test/lib)
  • Use Xcode open project test.

Android

  • Android Studio 3.5.3
  • The latest available example is in the demo2 folder (/openssl_for_ios_and_android/example/android/demo2).
  • Copy libcrypto.a, libcurl.a, libnghttp2.a, libssl.a four files to folder (/openssl_for_ios_and_android/example/android/demo2/test_curl_with_ssl_and_http2_android/app/src/main/cpp/test/lib) (armeabi-v7a, arm64-v8a, x86_64)
  • Use Android Studio open project test.

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
                       )

About "libcrypto.a(ui_openssl.o):ui_openssl.c:function read_string_inner: error: undefined reference to 'signal' " problem

when you get these error

libcrypto.a(ui_openssl.o):ui_openssl.c:function read_string_inner: error: undefined reference to 'signal' 

libcrypto.a(ui_openssl.o):ui_openssl.c:function read_string_inner: error: undefined reference to 'tcsetattr' 

You need to rebuild OpenSSL static library with NDK API level 16 or earlier

If you build OpenSSL with API level 16 or earlier you may not build it for arch 64 bit only support 32 bit
