"LLDB Provided No Error String" - Problem with XCode

Viewed 6874

I'm experiencing an issue with running an opencv program in Xcode. I keep getting this error: https://i.stack.imgur.com/F6Gpu.png . Xcode works with other opencv programs, so I have no idea what would be causing this issue & how I would go about fixing it. Any and all help would be greatly appreciated.

I had a same problem. I have Just unchecked: Target-> Edit Scheme -> Run -> Info -> Debug executable.

It works for me.

I had a same problem. I have Just unchecked: Target-> Edit Scheme -> Run -> Info -> Debug executable.

My solution was to delete /Application/Xcode.app as well as /Library/Developer and ~/Library/Developer and reinstall Xcode.

Edit: The error reappeared. Not sure why.

I had the Xcode-Beta versions installed and assume that that might have caused that.

A solution has been provided here, which would be:

sudo install_name_tool -add_rpath /Applications/Xcode.app/Contents/Developer/Library/Frameworks/ <toolchain path>/System/Library/PrivateFrameworks/LLDB.framework/Versions/A/LLDB

My professor said it has to do with the way your files are set up in the IDE, if you have the program reading in files from a folder you imported, you need to remove the reference to the folder, and go back and import each file individually rather than the folder as a whole. The IDE just sees the folder and doesn't actually see the files inside essentially
