Category: pd-extended Group: v0.39.2 >Status: Open Resolution: Postponed Priority: 5 Private: No Submitted By: stffn (stffn) Assigned to: Hans-Christoph Steiner (eighthave) Summary: delread~/delwrite~ not working on Intel Mac builds Initial Comment: There seam to be some issues some internal object for the intel mac build of Pd-extended-0.39.2-test7. The (known) objects that have problems are: [delwrite~] [delread~] [sqrt~] How they don't work ------------------- * sqrt~ of the signal 9 returns -\infty, hence not 3 as expected. All tried int signals greater then zero returns -\infty. To test this, see either the attached patch (which is very close to the help-patch for [sqrt~]) or the help-patch for [sqrt~]. See also: http://lists.puredata.info/pipermail/pd-list/2007-01/046266.html * delread~ and delwrite~ don't work in the sense that if one open the delread~ help file and change the value of the "input to delay line" number box. Then nothing happens in the number box connected to the snapshot, which was expected. See also: http://lists.puredata.info/pipermail/pd-list/2007-01/046077.html A "tried" solution ------------------ It has been suggested that it had to do with CPU optimizeing compile flags, see: http://lists.puredata.info/pipermail/pd-list/2007-01/046016.html I have done builds which tries different compile flags on my intel mac machine, and none of those builds have problems with the named objects, see: http://lists.puredata.info/pipermail/pd-list/2007-01/046044.html ---------------------------------------------------------------------- >Comment By: stffn (stffn) Date: 2007-06-12 14:18 Message: Logged In: YES user_id=1658640 Originator: YES In the autobuild from 12th of june it works on mac-intel (macbook core duo) and on powerpc (ibook G4). Both running Mac OS 10.4.9. ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-06-12 06:25 Message: Logged In: YES user_id=27104 Originator: NO I removed these from the compiler flags and it seems to have fixed the problem on Intel Macs: -ftree-vectorize -ftree-vectorizer-verbose=2 Please confirm that this is fixed in both Intel and PowerPC. This thread discusses the root causes of why the auto-vectorization causes this problem: http://lists.puredata.info/pipermail/pd-dev/2007-04/008689.html ---------------------------------------------------------------------- Comment By: stffn (stffn) Date: 2007-05-05 15:11 Message: Logged In: YES user_id=1658640 Originator: YES Still present in the nightly build of RC2 from 5th of May. It does however work in the test build of .040.2-extended of the same date. ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2007-04-02 01:17 Message: Logged In: YES user_id=27104 Originator: NO Following up on Steffen's tests, it sounds to me like this bug is probably caused by one of the patches in packages/patches. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2007-03-23 03:23 Message: Logged In: NO I will second this for ppc g4+ optimized version (iMac G5) - delays work but sqrt~ is getting the same problem. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1645862&group_id=55736 _______________________________________________ PD-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
