Description Daniel Macks 2010-03-13 10:40:32 PST
Platform: OS X 10.4/ppc with gtk built for x11 GUI and all dependencies at the level of current GNOME2.28 releases. 

Bug: Building webkit-1.1.15.4 fails at the linking stage of Programs/DumpRenderTree:

That symbol is a const in JavaScriptCore/API/JSClassRef.cpp, a file whose object is part of libJavaScriptCore.la. That lib is part of libwebkit-1.0.dylib and that symbol is part of libwebkit's public ABI. DumpRenderTree links against both libwebkit and libJavaScriptCore directly, so the symbol directly from libJavaScriptCore collides with the (re)exported one from libwebkit.

I tried to build DumpRenderTree without direct link to libJavaScriptCore, but that fails instead with:

/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: Undefined symbols:
WTF::fastMalloc(unsigned long)
WTF::fastFree(void*)

so it really does need libJavaScriptCore functions that are not public libwebkit bits. I then tried swapping the order of the libs in the linker call--libJavaScriptCore (a private convenience lib, like a pile of .o) before libwebkit ("external" public shared lib from the perspective of DumpRenderTree) and linking succeeded.

This is actually not tested against the nightly build and I don't know how to map public webkitgtk.org releases to webkit.org versioning, but the makefile segment looks the same in current SVN trunk.

I have applied the patch through a MacPorts Portfile, and confirmed that WebKitTools/GNUmakefile.am is correctly updated. However, it doesn't make any difference to the build failure. (This is on Mac OS X 10.4.11 PowerPC G5)

Please explain in the ChangeLog why this fixes the build failure.

Is this when also changing in the WebKitTools/GNUmakefile.am template, or just in the derived GNUmakefile.in derived file? The warnings suggest you are changing some template still, rather than just the higher level files in the built set. Or else if you are going to patch the low-level WebKitTools/GNUmakefile.am, propagate that change by redoing the autotools chain (autoreconf, or some similar command, not sure what is the recommended way for the webkit build system).

Can you get MacPorts to give a more verbose build, so you can verify that the order is changed in the actual linker call? 'make V=1' or passing --disable-silent-rules to ./configure or something like that? Is the -d flag relevant to debugging the build or just debugging the macports process?

As far as I can understand, MacPorts does not run automake by default, hence I have not run it at all.

I have now edited Makefile.in and run the build part again with MacPorts debug output, and I have now managed to change the order of the link (see the debug output configurelog2.txt attached: the last link includes:

-L/opt/local/lib ./.libs/libJavaScriptCore.a ./.libs/libwebkit-1.0.dylib /opt/local/lib/libenchant.dylib)


(I changed GNUmakefile.in)

However, it still gives the error about multiple definitions of symbol _kJSClassDefinitionEmpty.

I don't understand why changing the order would avoid the duplicate: if the symbol is defined twice surely it is defined twice whatever the order?

(Since I am not running automake, I think the warning is indeed a separate problem, and probably just a warning when the build is running, and reporting on the files it is using).

Comment 8 Martin Robinson 2011-08-07 02:38:40 PDT
I think this problem was a side effect of the fact that two copies of JavaScriptCore were compiled into DumpRenderTree. Free free to re-open this issue if it's still a problem on trunk.
