any advice for debugging crashing Alien FFI callbacks?
by Craig Latta 28 Sep '15

28 Sep '15

Hi-- I've got basic FFI connectivity going between Squeak 5 and a C library I want to use, via Alien. Callouts seem to work, and some callbacks. Other callbacks crash, though. I know which callback isn't successfully called, but I don't have the library source, so I'm not entirely sure what it's trying to do at that point. I'm on Mac OS 10.11. I attached lldb before the crash and am staring at the library's disassembled instructions. Does anyone have any advice for how to debug? thanks, -C -- Craig Latta netjam.org +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

It should be 51Deprecated then? ;) Best, Marcel -- View this message in context: http://forum.world.st/The-Trunk-50Deprecated-eem-1-mcz-tp4852032p4852077.ht… Sent from the Squeak - Dev mailing list archive at Nabble.com.

No MIDI ports found on Linux
by Stéphane Rollandin 27 Sep '15

27 Sep '15

Hello, Testing the 5.0 all-in-one from squeak.org in a Mint 17.2 running in VirtualBox (Windows 8.1 host), I see that SimpleMIDIPort midiIsSupported returns false with the linux VM, and true with the Windows VM (run though Wine). So it seems to me that the linux MIDIPlugin is broken (or am I missing something ?) Stef

Implementing #at:ifPresent:ifAbsentPut: without reusing #at:ifAbsent: and #at:ifAbsentPut: implies that it must be defined in some of its subclasses too to make it work. This is the reason why #at:ifAbsentPut: and #at:ifPresent:ifAbsent: reuse the low-level methods, sacrificing performance.

NS` how can I get programmatic reference to a particular category?
by robert 26 Sep '15

26 Sep '15

I must define variableByte subclasses in the category. Categories are not part of the namespace nor or symbols looked for there. SO I need programmatic access. I didn't find anything in the documentation, as it is an implementation issue. Could someone knowledgeable point out how I can do this? ty, Robert
