Harmony OS C++实战

开发步骤

1. 安装devcostudio打开
2. File->New->CreateProject->Native C++

cd src/main && git clone https://github.com/freetype/freetype && mv freetype/* cpp/

4. 多平台配置 新增build-profile.json5下abiFilters，支持多平台

   "externalNativeOptions": {

   "path": "./src/main/cpp/CMakeLists.txt",

   "arguments": "",

   "cppFlags": "",

   "abiFilters": [

   "x86_64",

   "arm64-v8a"

   ]

   }

5. 点击锤子🔨make module生成，右上角圆点切换debug|release。输出文件在build\default\outputs\default\*.hap，解压有ABI对应的.so文件。
6. ts或其它库调用使用时，需在src同级目录下新建libs文件夹，拷贝abiFilters所有文件夹到libs下。

.so cmake配置

cmake_minimum_required(VERSION 3.5.0)
project(NativeFileAccess)

set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})

if(DEFINED PACKAGE_FIND_FILE)
    include(${PACKAGE_FIND_FILE})
endif()

include_directories(${NATIVERENDER_ROOT_PATH}
                    ${NATIVERENDER_ROOT_PATH}/include)
link_directories(${NATIVERENDER_ROOT_PATH}/../../../libs/${OHOS_ARCH})

add_library(file_access SHARED FileAccessMethods.cpp)

if (CMAKE_BUILD_TYPE STREQUAL "Debug")
    set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libfreetyped.so)
else()
    set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libfreetype.so)
endif ()

set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libc++_shared.so)
target_link_libraries(file_access PUBLIC libace_napi.z.so libhilog_ndk.z.so librawfile.z.so libc++_shared.so)
target_link_libraries(file_access PUBLIC debug libfreetyped.so optimized libfreetype.so)

库依赖查看

readelf -d lib.so

注：so.x.x不支持，需用.so加载
