Qt IDE c / C ++ Is debugging mode very slow?

Question

I use Qt to develop a c / C ++ application, while I am trying to debug an application with a static library, it is very slow and takes a lot of (r) s time.

can anyone suggest me to make the debugger as fast as vs2008 ..

Regards VS

Answer 1

You probably have this behavior, because each time the debugger retrieves the required debugging information for system libraries from the Internet or does not find the requested information at all. If so, something like this appears in the Debug window.

Follow these steps to set up a character cache that allows you to cache debugging characters:

http://doc.qt.io/qtcreator/creator-debugger-engines.html#setting-cdb-paths-on-windows

This may slow down the next time you debug, but the second time it should be pretty fast.

If you do not have internet access, you will need to manually download these symbols here:

and put them in the symbol cache folder you specify.

Answer 2

it has nothing to do with windows and the debug symbol server this happens when libqt has debug symbols and it even (directly) happens in gdb / cgdb! this is due to the dwarf (still looking at it) regressed on windows (8), ubuntu (13.04), fedora (19-rc) and mac (10.8.5 and 10.9) -> obviously has little to do with os or library
