Common Issues
Profiles are not generated correctly.
- Possible cause 1: You do not have the write permission on the directory path where the profile is generated by -fcfgo-profile-generate. You can run the chmod 777 [Absolute path of the generation directory] command to solve the issue.
- Possible cause 2: The program does not exit normally. Upon application exit, __gcov_exit() is called to update profile information. You can attach to the application using GDB and manually call __gcov_exit() to resolve this.
