Hi all,
I encountered today while trying to build WebKitGTK+ in my old Ubuntu 12.10
box: my compilation failed at
Source/WebCore/Modules/webdatabase/SQLCallbackWrapper.h:79:91 with the
following error:
error: expression '<erroneous-expression> = <erroneous-expression>' is not
a constant-expression
The offending snippet of code is as follows, introduced two days ago in SVN
r167943 [1]:
scriptExecutionContextPtr->postTask({
ScriptExecutionContext::Task::CleanupTask, [=] (ScriptExecutionContext*
context) {
ASSERT_UNUSED(context, context == scriptExecutionContextPtr &&
context->isContextThread());
callback->deref();
scriptExecutionContextPtr->deref();
} });
After some investigation I found it to be a bug in GCC 4.7.2 (the version
shipped in Ubuntu Quantal), which are fixd now both GCC 4.7.3 and GCC 4.8:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54947
So, just sending this email here to let you know about this, in case you run
into the same issue.
Thanks,
Mario
