Bug 74387 – WebKit2 fails to clean-build at r102658

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Ryosuke Niwa]

It appears that WebKit2 fails to build at r102658:


The following build commands failed:

ERROR: WebKit2 has a weak external symbol in it (/Users/rniwa/webkit2/WebKitBuild/Debug/WebKit2.framework/Versions/A/WebKit2)
ERROR: A weak external symbol is generated when a symbol is defined in multiple compilation units and is also marked as being exported from the library.
ERROR: A common cause of weak external symbols is when an inline function is listed in the linker export file.
ERROR: symbol bool WTF::equal<unsigned char, unsigned char>(unsigned char const*, unsigned char const*, unsigned int)
ERROR: symbol bool WTF::equal<unsigned short, unsigned short>(unsigned short const*, unsigned short const*, unsigned int)
Command /bin/sh failed with exit code 1
Command /bin/sh failed with exit code 1

WebKit2:
	PhaseScriptExecution "Check For Weak VTables and Externals" /Users/rniwa/webkit2/WebKitBuild/WebKit2.build/Debug/WebKit2.build/Script-5DF408C5131DD46700130071.sh
(1 failure)

Not sure why the failure isn't reproducing on the bots

It appears that this problem is to do with http://trac.webkit.org/changeset/102631.

[Ryosuke Niwa]

To give you more context, I'm on Snow Leopard with gcc version 4.2.1 (Apple Inc. build 5666) (dot 3).

I've confirmed that WebKit build at r102630.

I changed the templates to overloaded functions in https://bugs.webkit.org/show_bug.cgi?id=74421.  Could you try  change set r102692: <http://trac.webkit.org/changeset/102692> and see if there is still a problem?

Okay, will do.

WebKit builds fine after the change.
