I once also had issues setting break points inside WebCore. Gdb claimed the break points have been set but the source code showing up after hitting the break point always messed up. The problem was resolved by updating my ubuntu to latest version (10.4LTS). I am not sure if this is the same problem you have.
Another tip is to check the size of your webcore.dll. It should be huge. Hopefully it helps.

Try This 1. As you already did run ./buid-webkit --debug --qt 2. cd WEBKIT_DIR/WebKitBuild/Debug/bin 3. Assuming you have WEBKIT_DIR/WebCore , WEBKIT_DIR/WebKit source directories try $ gdb -cd . -d ../../../ --args ./QtLauncher <args-to-QtLauncher> 4. Now at gdb prompt (gdb) break main # to add breakpoint to main function (gdb) break WebCore::FrameLoader::init # make sure you use fully-qualified namespace Alternatively 1. same as above 2. same as above 3. Create a text file with gdb commands $ cat <<EOF > commands.txt start break main break WebCore::FrameLoader::init continue EOF 4. run gdb as $ gdb -x comands.txt -d ../../../ -cd . --args ./QtLauncher Qt comes with (std distribution) with gdb 6.8 or something, if you gdb 7.01 or above you will be able to leverage some of the python gdb scripts distributed with WebKit See this WEBKIT_DIR/WebKitTools/gdb/webcore.py -- Chinmaya On Tue, Jul 13, 2010 at 8:22 PM, Yuchen Zhou <[email protected]<mailto:[email protected]>> wrote: Hi all- I am newbie to webkit dev and I am trying to debug Webkit with gdb. I tried to build the Qtwebkit with ./build-webkit --debug --qt, and then gdb WebKitBuild/Debug/bin/QtTestBrowser, however seems gdb was not able to add breakpoints for class::functions. It cannot find them. I wonder what is the debugging process for Qtwebkit.
