I'm asking here, rather than R-devel, because it seems to be a Linux specific question and because I'm using Ubuntu-9.04.
I'm trying to profile an package, and got errors, so I decided to follow BDR's (http://tolstoy.newcastle.edu.au/R/devel/06/02/4254.html) example exactly, and got same problem. Can anyone replicate? $ sudo mkdir -p /var/tmp//usr/lib/R/library/stats/libs $ chown -R pauljohn.pauljohn /var/tmp/usr/lib/R $ export LD_PROFILE=/usr/lib/R/library/stats/libs/stats.so $ R ### in R session, type >example(smooth.spline) > q() Observe that does create the profile file: $ ls -la /var/tmp/usr/lib/R/library/stats/libs total 20 drwxr-xr-x 2 pauljohn pauljohn 4096 2009-06-28 14:26 . drwxr-xr-x 3 pauljohn pauljohn 4096 2009-06-28 14:25 .. -rw-r--r-- 1 pauljohn pauljohn 1356800 2009-06-28 14:26 stats.so.profile $ sprof /usr/lib/R/library/stats/libs/stats.so /var/tmp/usr/lib/R/library/stats/libs/stats.so.profile Inconsistency detected by ld.so: dl-open.c: 652: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed! paulj...@pols124:Siena-Profiling$ sudo sprof /usr/lib/R/library/stats/ libs/stats.so /var/tmp/usr/lib/R/library/stats/libs/stats.so.profile Inconsistency detected by ld.so: dl-open.c: 652: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed! I Google to find one discussion that there's a bug in glibc that was unearthed in 2008 and there was debate on whether "sprof" is now deprecated. I don't understand the details completely. (http://sources.redhat.com/ml/libc-alpha/2008-08/msg00013.html) Nobody on Ubuntu has tried it lately? Instead of sprof, I'll try oprofile, I guess. I already tried to do this with gprof applied to the specific package, but no profile is produced. I believe that means I need to re-build all of R with the -pg flag, and I'm a bit reluctant to break everything by doing that. pj -- Paul E.
