PIE build fixes from upstream libmpeg2 (4.88 KB, patch)
2013-11-09 13:53 UTC, Jan Schmidt 		committed Details | Review

Description Elio Francesconi 2013-11-07 09:35:32 UTC 
I’ve recompiled right now the library and I noticed the binary are not
compliant with
Apple(https://developer.apple.com/LIBRARY/IOS/qa/qa1788/_index.html).
I think you should take care about this issue.

(null): PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic)
not allowed in code signed PIE, but used in MC_put_o_16_arm_align_jt
from /Users/elio/Library/Developer/GStreamer/iPhone.sdk/GStreamer.framework/GStreamer(libmpeg2_a_armv7_-motion_comp_arm_s.o). To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie
This is the only warning I received about PIE
Comment 1 Sebastian Dröge (slomo) 2013-11-09 10:14:08 UTC 
That's because some assembly code in libmpeg2/motion_comp_arm_s.S does absolute addressing unfortunately.

PIE build fixes from upstream libmpeg2

This is probably fixed by this patch from upstream svn that was never released.

Thanks, included that patch and it will be in the 1.2.1 release :)
