编译源码external目录下模块
测试环境：
LKD3588: Ubuntu 20.04
内核版本: 5.10.110
编译rockit/mpi
1、rockit源码位置：
SDK/external/rockit
2、将rockit文件夹拷贝到开发板/home/neardi目录。
3、默认的CMakeLists在开发板上编译会报错，rockit/mpi/CMakeLists.txt替换成以下内容：
cmake_minimum_required( VERSION 2.8.8 )
project (rockit)
include_directories(sdk/include)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
set(ROCKIT_DEP_COMMON_LIBS
${CMAKE_CURRENT_LIST_DIR}/../lib/lib64/librockit.so
)
set(ROCKIT_FILE_LIBS
${ROCKIT_DEP_COMMON_LIBS}
${CMAKE_CURRENT_LIST_DIR}/sdk/lib64/libgraphic_lsf.so
${CMAKE_CURRENT_LIST_DIR}/sdk/lib64/librkgfx_avs.so
)
set(ROCKIT_DUMPSYS_FILE ${CMAKE_CURRENT_LIST_DIR}/example/bin/bin64/dumpsys)
add_subdirectory(sdk)
add_subdirectory(example)
注意加入set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")， 否则会报以下错误：
/usr/bin/ld: ../common/librt_test_comm.a(test_mod_vpss.cpp.o): undefined reference to symbol 'pthread_create@@GLIBC_2.17'
/usr/bin/ld: /usr/lib/gcc/aarch64-linux-gnu/9/../../../aarch64-linux-gnu/libpthread.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
4、开发板安装编译环境
sudo update
sudo apt install gcc g++ clang make-guile build-essential cmake
5、开始编译
neardi@LPA3588:~/rockit/mpi$ cmake .

6、编译生成的文件在rockit/mpi/example目录。
7、测试

若测试提示缺少库，需要手动将编译出的so，拷贝到/usr/lib64目录下。
8、rockit使用手册
随SDK一起申请的文档查看：Linux->Multimedia->Rockchip_User_Guide_Linux_Rockit_CN.pdf，也可在百度网盘下载。
