[webkit-dev] Fwd: build-webkit stopped working for me

[Eric Seidel]

Is Snow Leopard deprecated?

Dave (WebKit's MathML guy) is reporting trouble building the Apple Mac
port on Snow Leopard.  We don't seem to have a Snow Leopard bot on:
http://build.webkit.org/console?category=AppleMac
so it seems totally concievable that it's broken.

If it is deprecated, I'm happy to post patches to remove support. :)

I'm sorry to bug you guys, but I don't know who else to ask. After my
last update-webkit, build-webkit --debug doesn't work for me. I tried
asking in IRC but got no response.

Below is some sample output. The script actually dies after failing to
compile 7 files in JavaScriptCore:
runtime/InitializeThreading.cpp runtime/Options.cpp
heap/GCThreadSharedData.cpp heap/SlotVisitor.cpp heap/Heap.cpp
heap/HeapStatistics.cpp heap/GCThread.cpp

I am running on Snow Leopard, to try to stay compatible with another
project (job). Has WebKit stopped supporting that for development? I
haven't seen any notice on webkit-dev e-mail. I notice that on
http://build.chromium.org/p/chromium.webkit/console the Mac OS 10.6
bots are failing, but they're failing tests not compiles.

All 7 compile failures are at the same place, so I've included 2 below
that together show how all 7 fail. At
/usr/include/c++/4.2.1/bits/locale_classes.h:411,
std::locale::facet::_M_remove_reference() (an internal C++ standard
library function) does a try/catch, but the gcc-4.2 command includes
-fno-exceptions. Do I need a later gcc (C++ standard library)? Is
there a way to find out what WebKit supports/requires, or what the
bots are using?

Thanks very much for any help or pointers. If there's someone better
for me to ask, please let me know.

Take care, Dave B.
