Bug 591

Summary: dynamic loading not working on systems using /usr/lib64
Product: SDL Reporter: Wade Berrier <wberrier>
Component: loadsoAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: sezeroz
Version: 1.2.13Keywords: target-1.2.14
Hardware: x86   
OS: Linux   

Description Wade Berrier 2008-05-28 11:09:42 UTC 
configure.in will enable dynamic loading by default for modules, but some of the checks only check /lib, /usr/lib, /usr/local/lib, etc...

It needs to also account for systems using /lib64, /usr/lib64, and /usr/local/lib64.

For example, openSUSE x86_64 distro uses these style paths.  Otherwise, i586 gets dynamically loaded, but x86_64 doesn't.

I tried attaching an attachment, but got an internal server error.  I'll post in here inline:

Comment 2 Ryan C. Gordon 2009-09-13 16:33:13 UTC 
Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).

--ryan.

This is fixed in subversion, thanks!
