i need libcurl to do something in dropbox djinni mx3 project; But when i create libmx3_android.so then show this error message: "undefined reference to 'curl_easy_init'"...... Because i can not link libcurl.a to this project.

for android jni, i find some solution can solve it; That is to eidt Android.mk 

include $(CLEAR_VARS)
LOCAL_MODULE:= libcurl
LOCAL_SRC_FILES := libcurl.a
LOCAL_EXPORT_C_INCLUDES := /* put the path to the Curl headers here */
include $(PREBUILT_STATIC_LIBRARY)

but in these project, .mk file will recreate by mx3.gyp. how to edit mx3.gyp to create that .mk file?

thx.

first of all, you will need the .a file compiled for all platform. you can find it here https://github.com/gcesarmza/curl-android-ios or compile yourself. Then you will also need to add as dependency

"targets": [
    {
        "target_name": "libapplication_jni",
        "type": "shared_library",
        "dependencies": [
          "../support-lib/support_lib.gyp:djinni_jni",
        ],
        "libraries": ["libcurl.a",],
        "ldflags": [ "-llog", "-lz", "-Wl,--build-id,--gc-sections,--exclude-libs,ALL" ],
        "sources": [
          "../support-lib/jni/djinni_main.cpp",
          "<!@(python glob.py generated-src/jni   '*.cpp')",
          "<!@(python glob.py handwritten-src/cpp '*.cpp')",
        ],
        "include_dirs": [
          "../deps/include",
          "generated-src/jni",
          "generated-src/cpp",
          "handwritten-src/jni",
          "handwritten-src/cpp",
        ],
    },
],

place your curl include files in the deps/include directory Lastly, place this at the begining of your Android.mk file

LOCAL_PATH:= $(call my-dir)

#ARM optimizations
ifeq ($(TARGET_ARCH),arm)
  PLATFORM_TARGET_ARCH := armeabi
endif
ifeq ($(TARGET_ARCH),arm64)
  PLATFORM_TARGET_ARCH := arm64-v8a
endif

#x86 optimizations
ifeq ($(TARGET_ARCH),x86)
  PLATFORM_TARGET_ARCH := x86
endif
ifeq ($(TARGET_ARCH),x86_64)
  PLATFORM_TARGET_ARCH := x86_64
endif

#MIPS optimizations
ifeq ($(TARGET_ARCH),mips)
  PLATFORM_TARGET_ARCH := mips
endif
ifeq ($(TARGET_ARCH),mips64)
  PLATFORM_TARGET_ARCH := mips64
endif

include $(CLEAR_VARS)
LOCAL_MODULE:= libcurl
LOCAL_SRC_FILES := /djinni/mobile/deps/prebuilt/android/$(PLATFORM_TARGET_ARCH)/libcurl.a
LOCAL_EXPORT_C_INCLUDES := /djinni/mobile/deps/include
include $(PREBUILT_STATIC_LIBRARY)

i hope it helps. thanks

'ldflags' : [ '-L$(LOCAL_PATH)/deps/curl', '-L$(LOCAL_PATH)/deps/zlib', '-llog' , '-lcurl', '-lz'],
