[webkit-dev] Debugging Webkit?

[Chinmaya Sn]

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
