Created attachment 449603 [details] Error output from linker Building with ./Tools/Scripts/build-webkit --wpe --no-unified-builds --debug ... after applying https://bugs.webkit.org/show_bug.cgi?id=235406 which fixes an unrelated link error Expected result: build success Actual linker output is in attachment. I am not sure if WebKitTestRunner is meant to link against libWebCore directly or not, the missing symbols are present there but conflict with some exposed by WebCore/testing/Internals.cpp (which are in libWebCoreTestSupport) and I am unfamiliar with how these are meant to interact.
Whoops, lmoura pointed out this is already tracked :0 *** This bug has been marked as a duplicate of bug 226088 ***
