Priority:	Major	Regression?
Status:	Closed/Complete	Components:	Core/BuildSystem
Versions:	1.8.8.0	Frequency of Occurrence	Constant
Related Issues:	is duplicated by ASTERISK-19126 Cannot install asterisk on mac os lion is related to ASTERISK-18728 Segfault in app_stack.so on Solaris
Environment:	Asterisk 1.8.8.0-rc4, i586 PC, gcc 3.4	Attachments:	( 0) config.log
Description:	The used gcc is version 3.4 which has weak attribute support (weak only). While building the target is succesful, running Asterisk immediately ends up in a seg fault. In optional_api.h the set HAVE_ATTRIBUTE_weak flag chooses code for MACOS which seems not to be suitable for a PC. Manually undefining the HAVE_ATTRIBUTE_weak flag in autoconfig.h solved the problem in my environment for now.

Thanks for reporting it! By: Thomas Arimont (tomaso) 2011-12-05 00:27:59.621-0600 Leif, I'm not sure if you've really understood this issue. For MacOSX Users this current behaviour should be fine, but not for i586/PC/gcc 3.4(at least) like me. So I don't know if the interest of the MacOSX community is really high, We maybe need MacOSX implementors which are PC-friendly to fix this, and respect the pluralistic world of operation systems ;-) By: Richard Mudgett (rmudgett) 2011-12-05 10:19:00.075-0600 Please try the patch attached to ASTERISK-18728. By: Thomas Arimont (tomaso) 2011-12-05 12:44:57.322-0600 Thanks Richard, looks reasonable, I will try it tomorrow and give some feedback ...
