Gem 0.87 Crash on Linux
by bbogart＠ryerson.ca 13 Feb '03

13 Feb '03

Hello all, I'm using pix_write and all of a sudden I'm having problems. It was working fine when I was doing 480x480 renders, then I was playing with the cropping in pix_write and ended up saving 38000 frames of 150x150 buffers cropped to 128x128! arg. anyhow now I'm just trying to save my 150x150 buffer and PD crashes when it tried to write the file. Here is the gdb stack: Program received signal SIGSEGV, Segmentation fault.

Hi, Got some (big) help (again) from Fernando @ planet-ccrma: ------start quote There is one missing library that gem has to link to. After doing the configure process, edit the Makefile (in src/Gnu) and add to the libs line "-lttf", that will link gem with the truetype library and will resolve the missing symbol. ------end quote I want to start testing the new objects tonight. Where should I report what works, what don't and what crashes pd? Is the PD-dev list the right place for this? thanks for the new toys!!

Bug in Pd-CVS devel_0_36 (with patch)
by Frank Barknecht 12 Feb '03

12 Feb '03

Hallo, could someone commit the patch below into the devel_0_36 branch of Pd on sourceforge? I'm constantly doing something wrong trying to checkout and commit it unanonymously (i.e. as "fbar") into the CVS. The patch fixes the "invalid command '.controls.in.clip'"-error on Linux, occurring if one turns on the peak meters. --- src/u_main.tk Thu Dec 12 13:17:45 2002 +++ src-new/u_main.tk Mon Feb 10 13:47:39 2003 @@ -2625,15 +2625,15 @@ global ctrls_inlevel ctrls_outlevel set ctrls_inlevel $indb if {$inclip == 1} { - .controls.in.clip configure -background red + .controls.inout.in.clip configure -background red } else { - .controls.in.clip configure -background grey + .controls.inout.in.clip configure -background grey } set ctrls_outlevel $outdb if {$outclip == 1} { - .controls.out.clip configure -background red + .controls.inout.out.clip configure -background red } else { - .controls.out.clip configure -background grey + .controls.inout.out.clip configure -background grey } } Thank you -- Frank Barknecht _ ______footils.org__

Hi again, Is there any other way than 'directory browsing' to know what new objects are in the cvs-Gem? Can I see/search that somewhere/somehow on sourceforge? grtz, kurt Original Message: ----------------- > I want to start testing the new objects tonight. > Where should I report what works, what don't and what crashes pd? Is the > PD-dev list the right place for this? I think the right place is the list. I wasn't very succesful when I tested them yesterday on Linux. Still have to figure out what happens.

[GEM] pix_video_ds: DirectShow video capture for Windows
by Daniel Heckenberg 11 Feb '03

11 Feb '03

Hi All, The first release of pix_video_ds, a DirectShow based live video capture object for Windows platforms can be found at: http://www.bogusfront.org Features: Flexible video capture from any DirectShow supported device, including DV cameras. Limitations: - Relatively untested - DirectShow is very complicated and I have only tested with a small number of devices. Try it and let me know how you go! - Requires DirectShow 8 or greater (perhaps 8.1 or greater?) - Binary only release. Links against GEM v0.87 I'll roll this object into GEM itself once it is stable and tested. A final note: I'll be travelling for the next week so I will not be able to provide any support/reply to any email until my return. Good luck, daniel ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Re: [PD] Universal Makefile for PD

[Cc'd to pd-dev in case other people can teach us the proper way to strip(1).] Hans-Christoph Steiner said this at Mon, 10 Feb 2003 10:36:22 -0500: >These tips were very helpful. I am on my way to porting my first >external: ext13. autoconf is quite straight forward. After I clear it >with Dieter, I'll commit my porting changes. > >I have a related question, is this needed?: >strip --strip-unneeded ext13.pd_darwin >strip: unrecognized option: --strip-unneeded > >And if so, what's the MacOS X equivalent? My first hacked together >ext13.pd_darwin lib works though. Hallo Hans-Christoph, I'm glad those suggestions were a help. I have no idea about "strip". I haven't used it, and I'm 95% sure it's not a necessary step. Looking at the Mac man page alone doesn't make it any clearer. However, from the Linux man page: --strip-unneeded Strip all symbols that are not needed for relocation processing. and now from the start of strip(1) in darwin-land: strip no longer removes relocation entries under any con- dition. Instead, it updates the external relocation entries (and indirect symbol table entries) to reflect the resulting symbol table. ...so it sounds like strip, as used here in Pd-land, is not terribly useful, but further on in strip(1)-darwin: When strip is used with no options on an executable file, it checks that file to see if it uses the dynamic link editor. If it does, the effect of the strip command is the same as using the -u and -r options. ... so that sounds to me like you might like to _experiment_ with strip using no options, and see if the default behaviour yields something that's still usable. :) Otherwise, if others know better about using strip, especially on Mac OS X, please chime in.

hiya, ...like the subject says: - several new geos: ripple: x/y center-able ripple distortion rubber: grab the image & stretch slideSquares: image revealed via sliding squares newWave: updated, added some controls - pix_texture2 changed to float gl commands - rectangle: added chris' glBlend code ...speaking of which, it'd be really nice if some nonMac platform could try this glBlending, cuz it could easily be added to all geo's...but we don't want to go overboard w/o confirmation... l8r, jamie

Setting up Access Control on pure-data CVS
by Hans-Christoph Steiner 11 Feb '03

11 Feb '03

So finally SourceForge posted the instructions for putting access control on the cvs respository: https://sourceforge.net/docman/ display_doc.php?docid=772&group_id=1#scriptcvsacls Basically, I think that cvs_acls would work well for us. It only restricts commits, so we would be free to import new sources. We need to come up with a "avail" file, which defines who has access to what. Here's a simple example: unavail avail|bob, alice|server avail|alice|docs avail|blackbart|website avail|cookiemonster Who wants want restricted? I'll set it up once we agree on the setup. .hc
