Question

我需要libcurl在dropbox djinni mx3项目中做一些事情; 但是，当我创建libmx3_android.so然后显示此错误消息：＆＃34;未定义参考＆＃39; curl_easy_init＆＃39;＆＃34; ...... 因为我无法将libcurl.a链接到这个项目。

对于android jni，我发现一些解决方案可以解决它;那是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)

但在这些项目中，.mk文件将由mx3.gyp重新创建。如何编辑mx3.gyp来创建.mk文件？

THX。

首先，您需要为所有平台编译的.a文件。你可以在https://github.com/gcesarmza/curl-android-ios找到它或自己编译。然后你还需要添加依赖

"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",
        ],
    },
],

将curl包含文件放在deps / include目录中最后，将其置于Android.mk文件的开头

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)

我希望它有所帮助。感谢
