The project could not be compiled. Would you like to open it in Null Source Code Access?

I have all the appropriate configurations necessary. I have updated the conanfile to reflect the short version of unreal engine that I am using (4.23). I am not sure if this is a linker issue, a permission issue, or something else? Please help.

Thank you!

So I sort of resolved the Permission issue by using chmod -R 777 on the given file and the new log is as follows:

I looked at your other issue and I am facing a similar issue but I am not sure if the conanbuildinfo.json is getting created the way you explained it.

adamrehn commented 4 years ago

The first error was clearly a permissions error regarding your Conan cache directory, as you noted. I can only assume that the permissions error was caused by you building the OpenCV package using sudo or copying the package cache from somewhere else.

The second set of output isn't showing any output from Conan whatsoever and then fails because the Conan output JSON file cannot be found, which suggests the conan install command isn't being triggered. Have you commented out the Process.Start() call in the OpenCVDemo class constructor at some point?
