Re: [cdt-dev] Pretty Printing STL Container in debugger

Hi Lukas,

Most likely your debug launch does not use DSF, but CDI. This can be switched in the launch configuration. In the launch configuration dialog, select your configuration. At the bottom it must say "Using GDB (DSF) ..."

Please also note that there is an ugly bug in gdb for strings. There is no fix for it available in gdb yet. However, you can put a workaround into your pretty printers: In StdStringPrinter#to_string, insert the following code right behing the line the calculates len

        if len > 100:
            len = 100

This will clip the maximum length of a string and gdb will not commit suicide on uninitialized strings.

I'll update the wiki.

Greetings, Jens.
