Debugger hangs.

[z80]

Hello.

CVI2017 debugger hangs on function H264_DVR_Init() for long time when I run debugging  debug.exe process eats more than 20% cpu time.

The same project under CVI2012 runs debugger normally.

What is the cause?


Project attached.

Hello z80,

Because the H264_DVR_* functions are performing debug logging, the application takes longer to execute, if the debugger is attached. After some time, the app eventually finishes. However, the program runs smoothly without the debugger attached.

Outputing debug output strings is an expensive operation. You could solve this delay if you could remove the debug logging from the library functions that you are using.

Best regards,

You can see the debug messages printed out in the Debug Output window:
