catkin build error related to rangenet_lib #28

Closed carto-zed closed 4 years ago

carto-zed commented 4 years ago

Dear authors,

I have encountered a problem while use "catkin build ......." command to build SUMA++, the error information is showed below.

I tried OpenCV 3.3.1, 3.4.1 and 4.1.0, but the same error occurred.

Could you please give me a hint about how to fix this error?

I have fix this error. There are different versions of OpenCV in my Ubuntu OS, cmake sometimes cannot find the same version while build rangenet_lib and semantic_suma.

Solution: specify the version of OpenCV package in rangenet_lib and semantic_suma. step 1. in rangenet_lib/CMakeLists.txt, specify the version of OpenCV in line 156, such as find_package(OpenCV 3.3.1 COMPONENTS core viz) step 2. in semantic_suma/CMakeLists.txt, specify the version of OpenCV in line 11, such as find_package(OpenCV 3.3.1 REQUIRED) step 3. in your workspace, catkin clean step 4. in your workspace, catkin build --save-config -i --cmake-args -DCMAKE_BUILD_TYPE=Release -DOPENGL_VERSION=430 -DENABLE_NVIDIA_EXT=YES
