cmakelist配置

add_library(native-lib SHARED src/main/cpp/native-lib.cpp)

多个cpp源文件配置

file(GLOB helloworld_SRC "src/main/cpp/*.cpp")add_library(testlala SHARED ${helloworld_SRC})

多个cpp配置

add_library(testlala SHARED src/main/cpp/native-lib.cpp src/main/cpp/test.cpp)

单个配置

add_library(testlala SHARED  src/main/cpp/test.cpp)

gradle 配置

   externalNativeBuild {        cmake {            path "CMakeLists.txt"        }//        ndkBuild{//            path "src/main/cpp/Android.mk"////        }    }android {    compileSdkVersion 26    buildToolsVersion "26.0.0"    defaultConfig {        externalNativeBuild {            cmake {                cppFlags "-frtti -fexceptions -std=c++11"            }        }        ndk {            stl "stlport_static"            abiFilters "armeabi", "armeabi-v7a"        }    }}

1、 添加头文件目录，可以多引用，但是不能缺，因为缺了就编译不过

include_directories(  "../../../myWindows"  "../../../"  "../../../include_windows")

2、添加环境变量，请结合实际项目要求，不是必须的

add_definitions( -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_REENTRANT -DENV_UNIX -DBREAK_HANDLER -DUNICODE -D_UNICODE)IF(APPLE)  add_definitions(-DENV_MACOSX)  FIND_LIBRARY(COREFOUNDATION_LIBRARY CoreFoundation )ENDIF(APPLE)

3、源文件

file(GLOB_RECURSE src_files  "../../../../C/7zCrc.c"  "../../../../C/7zCrcOpt.c"  "../../../../C/7zStream.c"  "../../../../C/Aes.c"  "../../../../C/Alloc.c"  "../../../../C/Bra.c"  "../../../../C/Bra86.c")

4、设置生成静态库以及名称

add_library(myLibName STATIC ${src_files})IF(APPLE)   TARGET_LINK_LIBRARIES(myLibName ${COREFOUNDATION_LIBRARY} ${CMAKE_THREAD_LIBS_INIT})ELSE(APPLE)IF(HAVE_PTHREADS)   TARGET_LINK_LIBRARIES(myLibName ${CMAKE_THREAD_LIBS_INIT})  ENDIF(HAVE_PTHREADS)ENDIF(APPLE)
