Compiling Externals with Visual C++ 7|.net
by aziz 07 Oct '03

07 Oct '03

hullo list, Ive just decided to start on externals programing, and came upon my first stumble, pd cant find the (extern)_setup method. I tried to find a solution in the mailing list, coming up to no_export clues. I dont know if its relevant or at all has been solved(compiling with msdev) but i just wanna share my 1 hour frustration(more has yet to come) and joy. It bore down to the fact that the linker doesnt export the function under a default dll project, nor could i find an easy setting in msdev to export that function. I found it easiest thus, i. start an empty win32 project ii. write your code (mine was just in one cpp) iii-a. under the property pages, go to Linker, go to Command line, then in the text box, Additional Options type /EXPORT:[extern]_setup iii-b. declare export dll with a microsoft specific modifier, __declspec, your setup function would look like this __declspec(dllexport) void foo_setup(void){} at first i thought i would be able to achieve this same thing only with extern (yes, too long no programming) or set the []_setup as the dll entry point, but didnt happen. I think iii-b, shouldnt be used because its not crosscompilable. Hey, any malaysian or aSean pd'ers | extern progammers out there? its lonely here! ; ]

hack to get Cmd keys working with Tcl 8.4.4
by Hans-Christoph Steiner 07 Oct '03

07 Oct '03

I found a way to get the Cmd/Apple key working in with Pd running in Tcl/Tk 8.4.4. I don't know if this is a good way to do it, but it works. In pd.tk: at around line 126, just below: bind . <Control-Key> {pdtk_pd_ctrlkey %W %K 0} bind . <Control-Shift-Key> {pdtk_pd_ctrlkey %W %K 1} add: if {$pd_nt == 2} { bind . <Command-Key> {pdtk_pd_ctrlkey %W %K 0} bind . <Command-Shift-Key> {pdtk_pd_ctrlkey %W %K 1} } and around 910, just below: global pd_nt if {$pd_nt == 2} { bind $name.c <Button-2> {pdtk_canvas_click %W %x %y %b 8} bind $name.c <Control-Button> {pdtk_canvas_click %W %x %y %b 8} add: bind $name.c <Command-Key> {pdtk_canvas_ctrlkey %W %K 0} bind $name.c <Command-Shift-Key> {pdtk_canvas_ctrlkey %W %K 1} but keep it above: } else { bind $name.c <Button-3> {pdtk_canvas_click %W %x %y %b 8} bind $name.c <Control-Button> {pdtk_canvas_click %W %x %y %b 2} } .hc http://at.or.at/hans/

cvs-commit list
by Hans-Christoph Steiner 06 Oct '03

06 Oct '03

I would like to set up a list for all cvs commits. Therefore, every time someone makes a commit to the repository, the commit comments get emailed to the list. Its handy to keep track of who is working on what. I have the functionality already setup, I just need a list to point it to. IEM seems the logical location since every other list is there, but I can easily set it up on SourceForge too. .hc http://at.or.at/hans/

adding IEMlib to the CVS
by Hans-Christoph Steiner 06 Oct '03

06 Oct '03

So I would like to add IEMlib to the CVS. I have tried emailing Thomas Musil about this but haven't heard back from him. Does anyone have any objections to me adding IEMlib to the CVS? .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

pd-cvs list

Unless there are some objections, I think this list should be created. Then I'll make CVS send emails on commits. .hc ________________________________________________________________________ ____ Man has survived hitherto because he was too ignorant to know how to realize his wishes.

CVS commits - no updates in viewCVS?
by ben＠ekran.org 02 Oct '03

02 Oct '03

Hey all, I've commited some new chaos and added the PSO external to the CVS. from the CVS side everything seems to work fine, it knows about the files, and has appropriate version numbers. The viewCVS function on sourceforge does not see these changes though. Is this only updated periodically? I also did a checkout the day after on another machine and indeed the pso was not included nor the new chaos code... I'm just copying files into my externals working copy (after cvs update -dP) then using cvs add for each one (including directories) and finally doing cvs commit. No errors or other issues... What am I missing? Thanks! Forgive my lack of CVS experience. Ben

minor header change to make externals compile on all versions of Pd
by Hans-Christoph Steiner 02 Oct '03

02 Oct '03

If the pd headers did this, then externals could compile on both <= 0.36 and 0.37 without changes: /* Copyright (c) 1997-1999 Miller Puckette. * For information on usage and redistribution, and for a DISCLAIMER OF ALL * WARRANTIES, see the file, "LICENSE.txt," in this distribution. */ #ifndef __m_pd_h_ ... #define __m_pd_h_ #endif /* __m_pd_h_ */ This is most needed on m_pd.h, but I think it couldn't hurt in the other headers that are commonly used by externals: m_imp.h, s_stuff.h, g_canvas.h. Thomas Grill has had this change in the CVS devel_0_3? version for a while now, so I think its well tested. .hc ________________________________________________________________________ ____ There is no way to peace, peace is the way. -A.J.

netsend/netreceive issue with SIG_PIPE
by Jerome Etienne 02 Oct '03

02 Oct '03

Hello, im using pd-0.36(likely from ccrma) on a redhat9, and netsend doesnt handle SIG_PIPE. so if i connect a pd patch to another program via netsend and the network connection between the two is lost, puredata crash because of SIG_PIPE. i think it would be good not to have pd crashing because of a very remote network problem. is there a puredata version with a better handling of network connection ? is it valuable for others if i write and send the patch ?
