cmake编译android平台的libPoco

1、下载源代码，解压到POCO-1.7.8-ALL

2、从$ANDROID_NDK\cmake下复制android.toolchain.cmake AndroidNdkGdb.cmake AndroidNdkModules.cmake至POCO-1.7.8-ALL\cmake\下

3、vim POCO-1.7.8-ALL\cmake\android.cmake，内容如下

#cd POCO-1.7.8-ALL

#mkdir BUILD && cd BUILD

#cmake -DCMAKE_CXX_FLAGS='-frtti -fexceptions -fpermissive'  ..

#make -j4

set(CMAKE_BUILD_TYPE Release)

set(ANDROID 1)

set(CMAKE_CXX_FLAGS "-fexceptions")

set(CMAKE_CXX_FLAGS_DEBUG -fexceptions)

#set( $ANDROID_NDK/toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/bin)

set(CMAKE_TOOLCHAIN_FILE ${CMAKE_CURRENT_SOURCE_DIR}/cmake/android.toolchain.cmake)

set(ANDROID_STL stlport_static)

set(ANDROID_NDK /Users/musictom/Library/Android/sdk/ndk-bundle/)

set(ANDROID_TOOLCHAIN_NAME aarch64-linux-android-4.9)

set(ANDROID_ABI arm64-v8a)

set(ANDROID_NATIVE_API_LEVEL android-24)

set(CPACK_PACKAGE_INSTALL_DIRECTORY "/libs")

#add_compile_options(-std=c++11)

#message(STATUS "optional:-std=c++11") 

4、

cd POCO-1.7.8-ALL

mkdir BUILD && cd BUILD

cmake -DCMAKE_CXX_FLAGS='-frtti -fexceptions -fpermissive'  ..

make -j4
