More spicy

Wednesday, April 19, 2017

Spending more time trying to get to the bottom of why spicy on the Mac does not draw anything, now that I finally got debugging partially working.

Spice for Mac

Placed a breakpoint in all callbacks which seemed to make sense. None of them is called from the main loop. I may have to look directly into glib to get to the bottom of this.

Interesting that we only enter channel_new once. That seems wrong. Maybe the protocol aborts somewhere.

Spice with recorder

Made a change to the recorder so that there is no recorder.tbl in the project unless you build it. Adjusted ELFE and the version of Spice with recorder to match.

This time, I tried to make things cleanly in Makefile.am, and I ran into a couple of interesting issues. It looks like automake does not like to have sources in subdirectories much.

src/Makefile.am:215: warning: source file 'recorder/recorder.cpp' is in a subdirectory,

src/Makefile.am:215: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.  However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

This is theoretically fixed by adding the following to Makefile.am: 

AUTOMAKE_OPTIONS = subdir-objects

Also need to add AC_PROG_CXX to configure.ac, and a switch to select C++11 from autoconf-archive:

AC_LANG([C++])

AX_CXX_COMPILE_STDCXX_11

A little more fiddling, and I finally get something that appears to work enough that I can dump the recorder in a debug session:

(lldb) p recorder_dump()

That does not really tell me why I have no window. Looking for the origin of the message

This is the work blog of Christophe de Dinechin for Red Hat. Think of it as a public lab book.

This should not be particularly interesting except to myself. It's really more intended as a set of personal notes, so there is no formatting whatsoever. I type tings as I go along during the day. All you'll find here are things like stack traces, Linux commands I want to remember or bugzilla links I want to be able to return to.

If you want to read stuff about my work at Red Hat that I believe is more interesting to the general public, you will find it on A Spice Odyssey. If you want to read my rants about everything else, go to Grenouille Bouillie. This is about as much advertisement as you will find on this site.
