Can you try to modify the include statements and add the prefix IL as in 

#include <IL/devil_cpp_wrapper.hpp>
McCannDahl commented 1 year ago

Hmmm no same error image image

simogasp commented 1 year ago

It seems like that the wrapper is not installed anymore, at least in homebrew. As a quick workaround you can comment the find_package(DevIL COMPONENTS IL ILU)at line 82 of src/applications/detection/CMakeLists.txt. Devil is only optional and if not found it will fallback to opencv for loading the images.

That worked and the make passed. But when I run the detection example it says "Library not loaded: @rpath/libCCTag.1.0.3.dylib"

Did you do a make install? It's strange that it looks for libCCTag.dylib in /opt/homebrew/lib/ and other system paths like that. Usually it should be in ./build/Darwin-arm64/. You can try to run 

export DYLD_LIBRARY_PATH=/Users/path/to/build/Darwin-arm64/:${DYLD_LIBRARY_PATH}

replacing the path/to/ with your path to the build directory. And there run detection as you did.

I switched over to my PC and got it to work. We can close this for me or leave it open for other mac users
