Compile Modules in the external Directory of the Source Code
Testing Environment:
LKD3588: Ubuntu 20.04
Kernel Version: 5.10.110
Compile rockit/mpi
Location of the rockit source code:
SDK/external/rockit
Copy the rockit folder to the
/home/neardidirectory on the development board.Replace the default CMakeLists file in
rockit/mpi/CMakeLists.txtwith the following content:
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 ${CMAKE_CURRENT_LIST_DIR}/example/bin/bin64/dumpsys)
add_subdirectory(sdk)
add_subdirectory(example)
Note: Add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread") to avoid the following error:
/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
Install the build environment on the development board:
sudo update
sudo apt install gcc g++ clang make-guile build-essential cmake
Start the compilation:
neardi@LPA3588:~/rockit/mpi$ cmake .
