RE: [PD-dev] comport for OSX
by Brian Sheehan 12 Aug '03

12 Aug '03

Hi ben, I ported some serial port code that was written for windows to Mac OS X recently. You will pretty much have too rewrite the windows code, as the API is completely different on both platforms. That said, it's not that hard a job. I'm attaching two files, one with windows serial code, and another with the ported code. Note: the function SetLastError() is a windows api function. For the Mac OS X version of the code, I provided a function of this name which threw an appropriate exception. You could use this function to set errno or whatever suits your purposes. By the way, I'm using a keyspan serial port adapter (USA19QW), it works great.

Introduction, GEM 0.87 G++3.2.1 and Gentoo Linux
by Lee Azzarello 11 Aug '03

11 Aug '03

Hi all. I'm new here. I've been using Max/MSP/softVNS for a few years and have made the switch to Linux for multimedia. I read a glowing review of using GEM and PD for a multimedia installation so I grabbed the source code and gave it a go. It appears that version 0.87, which is the only version on the website, has some real linking problems. I'm just getting into Linux development, so I'm partially familliar with the magical autoconf system, but this looks like it goes beyond an autoconf thing. Issues I've encountered: 1) Whoever made the source tarball kept their Makefile in there. Without doing a 'make distclean', ./configure reported a bunch of wrong paths because it was using cached info from whoever made the tarball. 2) I have libmpeg3 installed and the headers are in /usr/include/libmpeg3/libmpeg3.h ./configure does not recognize this. 3) memcpy, a function provided by the string.h standard C library, is not included in some files in the Pixes directory. I included this and things are a little better. 4) The source won't compile on my system. For me it bails out here: echo ----------../Pixes---------- make[1]: Entering directory `/usr/local/src/gem-0.87/src/Pixes' g++ -c -g -fPIC -I../ -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/include/gltt -I../../../GemLibs/particle -I../../../GemLibs/liborb -I../../../GemLibs/glm -I/usr/local/include -I.. pix_videoLinux.cpp -o pix_videoLinux.o In file included from ../Pixes/pix_video.h:20, from pix_videoLinux.h:38, from pix_videoLinux.cpp:44: ../Base/GemBase.h:27:8: warning: extra tokens at end of #endif directive pix_videoLinux.cpp:59: default argument given for parameter 1 of ` pix_videoLinux::pix_videoLinux(float = 320, float = 240)' pix_videoLinux.h:68: after previous specification in ` pix_videoLinux::pix_videoLinux(float = 320, float = 240)' pix_videoLinux.cpp:59: default argument given for parameter 2 of ` pix_videoLinux::pix_videoLinux(float = 320, float = 240)' pix_videoLinux.h:68: after previous specification in ` pix_videoLinux::pix_videoLinux(float = 320, float = 240)' make[1]: *** [pix_videoLinux.o] Error 1 make[1]: Leaving directory `/usr/local/src/gem-0.87/src/Pixes' make: *** [subdirs] Error 255 Which is also in the Pixes directory, which seems to be where most of the compilation problems are. I read on the list archives that about a year ago there was an issue with G++ 3.0. It seems these problems are still there. I have version 3.2.1 installed and so far GEM is the only software giving me problems. So what's required to get the source G++ 3.0 compatible? -l[e^2] ------------------------------ http://www.fallingforward.net/ people experimenting with music, art and technology

combining flext externals in a library?
by Marc Lavallée 09 Aug '03

09 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Thomas. I like to build flext externals individually and also combine them into a library. The "lib1" tutorial shows how to build an external with many internal objects, but not how to combine individual flext externals into a library. - -- Marc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE/M8StQdzoeKQ0PccRAgwJAJ91QcpBUmjRQSO0szG31Qyqrkjg4gCfU71S iLf1LMFwX0ubrhcqHS5MsN8= =FkOC -----END PGP SIGNATURE-----

FLEXT: ToOutList(), Append(), and AtomList()
by ben＠ekran.org 09 Aug '03

09 Aug '03

Hello all, I'm looking through the flext documentation and am having trouble figuring out how to send a list of floats. The length of the lists and the number of lists is variable. The floats I will be inserting as a list currently exist as a float array, but the contents would need to be reordered somewhat. My guess is you first define the vars to store the lists in the class, then use Append in a loop at add the array values to the list, and then send out with ToOutList(). But what variable type should the list variable be? If anyone has an example around please send it along. Thanks Ben

redirecting PD post output
by Thomas Grill 08 Aug '03

08 Aug '03

Hi, another thing that would be interesting for some of my applications is to redirect the output of the post function. I don't know if it's the best solution but a callback function could be set for that. If it's not set, output goes to stderr as ever. Probably there should also be a possibility for more than one instance to access the post output but this is not of importance for me. Irrelevant? Or any other ideas? best greetings, Thomas

Creating Gem Chain over network
by ben＠ekran.org 08 Aug '03

08 Aug '03

Hey all, I'm wondering what is the best way to pass whole objects, or even better the whole GL scene from one machine to another over network? So it gets rendered on one machine, but all the control patch stuff is on another machine. I was thinking that it may be possible to send the gemchain over socket connections as one can send them over PD send and receives. for example you have a gemhead on machine A, sending over a socket to machine B. Machine B connects the socket output to a gem chain. The output of the gem chain is sent via another socket connection back to machine A where its connected to a geometry object. Anyhow I'd love to hear any thoughts on the matter. Thanks Ben

graphical arrays & subpatches
by Brian Sheehan 08 Aug '03

08 Aug '03

Hi, I have an object that writes to a graphical array. The array to write to is specified by one of the objects creation arguments. I would like the array to be drawn in a subwindow. But unless the subwindow is actually open at object creation time, the object won't find the array. Is there a way around this? Here's the code I use to find the array (courtesy of tabwrite~): t_garray *a; x->display_vec_name = s;//s is a symbol if (!(a = (t_garray *)pd_findbyclass(x->display_vec_name, garray_class))) { if (*s->s_name) pd_error(x, "squiggle~: %s: no such array", x->display_vec_name->s_name); x->display_vec = 0; } else if (!garray_getfloatarray(a, &x->display_size, &x->display_vec)) { error("%s: bad template for squiggle~", x->display_vec_name->s_name); x->display_vec = 0; } thanks, Brian p.s. Is there any way of creating a graphical array from within an external object? It'd be cool if my object could create an array of the correct size for its purposes, rather than me having to do it every time I use the object. __________________________________ Do you Yahoo!?

anonymous GEM CVS access
by ben＠ekran.org 08 Aug '03

08 Aug '03

Hello all, Did I miss something or does anonymous checkout from the sourceforge CVS for Gem not work? I'm entering (on linux): cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/pd-gem login and getting: Logging in to :pserver:anonymous@cvs.sourceforge.net:2401/cvsroot/pd-gem CVS password: cvs [login aborted]: recv() from server cvs.sourceforge.net: EOF when the CVS password is [enter] (the key, not the string!) is anyone else having this trouble? I've not done a externals co in a while, but I remember having to do so with my sourceforge ID because I could not get anonymous CO to work.... I do remember people taking about sourceforge CVS issues? Thanks Ben
