djiros compilation problem

[GaoZiHong]

I installed the Onboard-SDK according to the tutorial and cloned djiros in the ROS workspace. When I execute the catkin_make command, it gives me the following error: CMake Error at djiros/CMakeLists.txt:36 (find_package): By not providing "FindDJIOSDK.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "DJIOSDK", but CMake did not find one.

Could not find a package configuration file provided by "DJIOSDK" with any of the following names:

DJIOSDKConfig.cmake
djiosdk-config.cmake

Add the installation prefix of "DJIOSDK" to CMAKE_PREFIX_PATH or set "DJIOSDK_DIR" to a directory containing one of the above files. If "DJIOSDK" provides a separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred! See also "/home/dji/catkin_ws/build/CMakeFiles/CMakeOutput.log". See also "/home/dji/catkin_ws/build/CMakeFiles/CMakeError.log". Then I added "set(DJIOSDK_DIR /home/dji/Onboard-SDK/osdk-core/advanced-sensing/ori-osdk-core/cmake-modules)" to the CMakeList.txt file and recompiled, the results are as follows: CMake Error at /home/dji/Onboard-SDK/osdk-core/advanced-sensing/ori-osdk-core/cmake-modules/DJIOSDKConfig.cmake:11 (include): include could not find load file:

Our djiros is modified from the official Onboard-SDK-ROS, so it needs OSDK like the official dji ROS package does. Therefore, as I mentioned in issue#37, you have to make sure the official Onboard-SDK-ROS can run successfully. Then our djiros can be compiled as will. Since the platform you use is different from ours, we are unable to solve these compiling errors.

I successfully solved the last problem. But after I copied the code in onboard_computer to the newly created ros workspace and compiled it, the following problems occurred: /home/dji/catkin_ws/src/controller/djiros/src/djiros/DjiRosAuthority.cpp: In static member function ‘static void DjiRos::on_authority_ack(DJI::OSDK::Vehicle*, DJI::OSDK::RecvContainer, DJI::OSDK::UserData)’: /home/dji/catkinws/src/controller/djiros/src/djiros/DjiRosAuthority.cpp:32:32: error: ‘PackageMin’ is not a member of ‘DJI::OSDK::OpenProtocol’ if (recvFrame.recvInfo.len - OpenProtocol::PackageMin <= (int) sizeof(uint16 ^ controller/djiros/CMakeFiles/djiros_node.dir/build.make:137: recipe for target 'controller/djiros/CMakeFiles/djiros_node.dir/src/djiros/DjiRosAuthority.cpp.o' failed make[2]: [controller/djiros/CMakeFiles/djiros_node.dir/src/djiros/DjiRosAuthority.cpp.o] Error 1 CMakeFiles/Makefile2:1832: recipe for target 'controller/djiros/CMakeFiles/djiros_node.dir/all' failed make[1]: [controller/djiros/CMakeFiles/djiros_node.dir/all] Error 2 Makefile:138: recipe for target 'all' failed make: *** [all] Error 2 Invoking "make -j1" failed how can i solve it?

We have now compiled all the code. As for the previous problem, we changed the library name you provided and solved the problem. What external network card do you choose? We want to use the same network card as you.

@G1246830895 I don't think the wireless card warrants a discussion here under this research-oriented project. You can choose whatever wireless card with nothing different I guess.
