• FDbus NDK以及QNX交叉编译

    1. 背景

    fdbus 可以这讲，就是一个定制化的RPC，可以用于进程间通信，以及双系统间通信。

    TODO

    2. 下载资源

    fdbus镜像地址：fdbus

    Android ndk下载：Android ndk

    QNX tools下载： prebuilt_QNX700

    下载完，解压！

    TODO

    3.  实操

    废话不多数，直接上编译脚本

    3.1  QNX交叉编译脚本

    如上，但是ndk编译会报错。 //如下信息

    ld: error: undefined symbol: __android_log_print
    >>> referenced by CBaseClient.cpp:101 

    .....
    clang++: error: linker command failed with exit code 1 (use -v to see invocation)
    CMakeFiles/common_base.dir/build.make:533: recipe for target 'libcommon_base.so' failed
    make[2]: *** [libcommon_base.so] Error 1
    CMakeFiles/Makefile2:262: recipe for target 'CMakeFiles/common_base.dir/all' failed
    make[1]: *** [CMakeFiles/common_base.dir/all] Error 2
    Makefile:129: recipe for target 'all' failed
    make: *** [all] Error 2

    没关系，一看是缺少链接库log导致的

    那么修改cmake/CMakeLists.txt

    增加如下code：

    1. 	if(fdbus_ANDROID)
    2. 		link_libraries(log)
    3. 	endif()

    ​

    再次编译：

    ./build_android.sh 

    编译OK
