I years ago debugging good program, open the test a few days ago to find out a lot of error cannot resolve the symbols, sadness, below is the figure

After debugging good hasn't changed anything, ever bosses told what's going on, the path of the link what I have looked at the inside, there is no change,

CodePudding user response:

Since all debugging good why return to regenerate?
What is apparently due to system update, library is missing,
