swrast_dri.so.tmp: undefined reference to `clock_gettime'


16f0d70ffe6d42d22b9e6b927b297e75a199aa78 is the first bad commit
commit 16f0d70ffe6d42d22b9e6b927b297e75a199aa78
Author: James Benton <jbenton@vmware.com>

    llvmpipe: Implement PIPE_QUERY_TIMESTAMP and PIPE_QUERY_TIME_ELAPSED.
    
    This required an update for the query storage in llvmpipe, there
    can now be an active query per query type, so an occlusion query
    can run at the same time as a time elapsed query.
    
    Based on PIPE_QUERY_TIME_ELAPSED patch from Dave Airlie.
    
    v2: fix up piglits for timers (also from Dave Airlie)
    
    a) if we don't render anything the result is 0, so just
    return the current time
    
    b) add missing screen get_timestamp callback.

help either case?

we may need to fix the patch posted her to use CLOCK_LIB.

Patch from proposed link doesn't fix the linking process. However, Laurent's patch does the trick for both 64 and 32 bit builds (cross compilation).

Comment 6 Dave Airlie 2012-12-04 08:03:20 UTC

should be fixed in master now. reopen if not.
