FS#8906 - Simulator fails to launch under MacOS

Compiled simulator from r17646 under MacOS 10.4.11.
Compile completed successfully, but rockboxui fails to launch.
Displays Rockbox logo/version screen, then freezes, while still placing significant load on CPU.
Observed some warnings during the compilation of rockboxui, but nothing which stopped the process.

I’m happy to provide any further information needed to track this down.

Not a Rockbox bug, anyway…

Personally, I’d recommend including the warnings, so we can get that question out of the way from the beginning.

Good point. Here they are:

Also, I haven’t built every target simulator, but I can report the following:
iriver H300, H100: behave as described above
iPod Color: gets to menu screen before freezing
Archos Recorder: works fine

Hi Phil, could you try adding -fvisibility=hidden to the end of the line beginning with GCCOPTS in your <simbuilddir>/Makefile ?

Hi Nils
That doesn’t seem to make any difference: same compiler warnings, same behaviour of rockboxui.
(Only tested with H300 simulator)

nls commented on 2008-04-19 08:54

Did you ‘make clean’ after that change?

Yes, I did.
Can you replicate it, or is it just me?

More information: I’m not sure that the compiler warnings are related.
I see the same warnings with r16681 (to pull a number out of the air), and that produces a working rockboxui.
I’m working my way forward, looking for the point where it stops working for me, and I’ll report back when I find it.
(Tomorrow–bedtime in my timezone now.)

Those warnings have always been there for Mac OS X; it’s new that the simulator doesn’t load at all. I updated to r17146 and built the h300 simulator. Rockboxui froze with and without backgrounds. If I get a chance, I’ll look at this some time after exams and try to find which commit broke the simulator.

OS: Mac OS X 10.4.11
GCC: i686-apple-darwin8-gcc-4.0.1
ld: Apple Computer, Inc. version cctools-622.9~2

Note: r17171 has the same behavior.

The last working build for me is r16790, and from r16791 the issue described above appears.

It seems to me that these warnings should be resolved first, and the author of the relevant commit agrees that it’s really hard to debug something without knowing that the warnings aren’t partly to blame.

Warning: Undefined array key "useheading" in /home/rockbox/flyspray/plugins/dokuwiki/inc/parser/xhtml.php on line 1099 Warning: Undefined array key "target" in /home/rockbox/flyspray/plugins/dokuwiki/inc/parser/xhtml.php on line 557 Warning: Trying to access array offset on value of type null in /home/rockbox/flyspray/plugins/dokuwiki/inc/parser/xhtml.php on line 557

I did some research into this and discovered the problem. There’s nothing wrong on the Rockbox end of things, it’s a bug in SDL for Mac. See my discussion with jhMikeS at http://www.rockbox.org/irc/log-20080502#08:00 . In the discussion I link to an SDL bug report that has a patch to correct the problem. Rebuild SDL with the linked patch and the simulator should be working again.

That’s it. Thanks very much for tracking this down.
