webkit-gtk 1.1.15.4: multiple definitions of symbol _kJSClassDefinitionEmpty

[vinc17@…]

I get the following error under Mac OS X Tiger:

[vinc17@…]

Actually the error is due to

  CXXLD  Programs/DumpRenderTree

(this is because -j2 was used).

[guy.linton@…]

I get the same error, also on Mac OS X Tiger (10.4.11), but in my case, the build has -j1 in the make command:

Debug log of webkit-gtk install failure

[guy.linton@…]

This seems to be noted as a bug upstream: ​https://bugs.webkit.org/show_bug.cgi?id=36088, but I am not sure whether it is being fixed.

[guy.linton@…]

I have applied the patch in bugs.webkit.org bug 36088 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).

Do I need to do something else to make the patch to the GNUmakefile.am file take effect?

Portfile changed since last build; discarding previous state.

The GNUmakefile at the top level still has the Programs_DumpRenderTree_LDADD in the wrong order, but manually changing the order of these gives a warning about the process, but ultimately still gives the same error:

Replying to guy.linton@…:

Do I need to do something else to make the patch to the GNUmakefile.am file take effect?

Automake needs to be rerun. The first log doesn't contain the beginning of the output, but from the second one, it seems that you haven't installed the automake port (the warning message is a bit strange, though... this could be another problem).

[guy.linton@…]

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).

This is not specific to MacPorts. The autotools (automake, autoconf, libtool...) are utilities for developers. They should only be needed when some files of a tarball are patched (e.g. Makefile.am, configure.in) or when the source files are taken from a version control system (Subversion, git...). Depending on how the Makefile has been generated, there can be some rules to automatically (re)run the autotools when this is needed (a.k.a. maintainer mode).

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?

I agree.

Cc Me!

[elelay (Eric Le Lay)]

hi, webkit-gtk has been updated to 1.2.4.

It builds fine for me on 10.4.11 ppc G4.

[dbevans (David B. Evans)]

webkit-gtk was updated to 1.2.5 in r72215 which also builds correctly on 10.4.11 ppc.
