WebKit-r43887/WebKit/qt/tests/qwebpage> valgrind --track-origins=yes ./tst_qwebpage However, in this case it uses the WebKit library installed by Qt 4.5.1, instead of the one I build within my WebKit-r43887 folder. Is there anyway I can configure this (or other unit test) to use the compiled webkit lib? I tried running the tests at WebKit-r43887/Programs/unittests/ , but I'm not sure they do the sam thanks 186478 2 kling 2010-02-01 10:32:48 -0800 *** This bug has been marked as a duplicate of bug 33468 ***
