pmpd and question about compiling cvs on windows
by cyrille henry 11 Apr '04

11 Apr '04

hello, I solve my cvs problem. So pmpd is now on the pd external CVS. I noticed that the pmpd makefile I update from cvs is not exactelly the same that the one I commited : the file look the same, but the problem is that I can't compill pmpd on windows from an cvs update. makefile(4) : fatal error U1035: syntax error : expected ':' or '=' separator Stop. (in fact, I've got the same error whatever external I want to compill) I think that linux/windows incompatibility (with cariage return / line feed) generated this problem. I tried to open the makefile, copy the text in another file, and save back to makefile, in order to supress carriage return problem. this work : it suppress the error, and compilation work. so, is there a generique solution? a flag to set somewhere??? I'm not able to compill the rest of the cvs for the same reason. (I use WinCvs) thanks Cyrille

./configure --without-mpeg3 --without-ftgl --with-quicktime --with-avi --with-ieee1394 --enable-mmx --with-gltt PD\'s reported error: /usr/local/lib/pd/extra/Gem.pd_linux: /usr/local/lib/pd/extra/Gem.pd_linux: undefined symbol: _ZN8GLTTFont12setPrecisionEd ./configure --without-mpeg3 --with-ftgl=/usr/local/lib/libftgl.so --with-quicktime --with-avi --with-ieee1394 --enable-mmx --without-gltt Works! Hurray! Yippe! Thanks. I tryed disabeling everything and gem just hangs, but it seems that this works! I havent tested it yet in operation, but I loaded a patch with a lot of gem objects in it and it didnt crash! Thanks! -thewade PS: Whats up with gltt? is my version to old, even though its only a minor version different then yours? My gltt: gltt-2.5.2-2 Your gltt: gltt-2.5.2-313

Thanks for the help B. Bogart, Heres what I ran: Gem CVS, last updated Mar 25 rpm -q gltt gltt-2.5.2-2 ./configure --without-mpeg3 --with-ftgl=/usr/local/lib/libftgl.so --with-quicktime --with-avi --with-ieee1394 --enable-mmx --with-gltt checking for open in -lgltt... (cached) yes I tried running gdb, but the only command I know of is for finding program failures like seg faults, the where command, which doesnt help in this case. Thanks for the help! -thewade > Hi, > > Looks like GLTT is having issues, did you configure with: > > ./configure --with-gltt --without-ftgl > > or just ./configure? > > did the configure output say something like: > > checking for open in -lgltt... yes > > Could be your version of gltt is too old or too new? > > rpm -q gltt > > gives me: > > gltt-2.5.2-313 > > B. > > thewade wrote: > > >By now we all know that Ive had no end of trouble getting gem to work.

externals/build/doc makefile
by Hans-Christoph Steiner 09 Apr '04

09 Apr '04

Just an FYI: I replaced the copies of the help files that were in externals/build/doc with a makefile that copies the helpfiles from their source into that directory. I added a line to externals/build/linux/makefile to use that makefile so the debian packages should still get their doc files. .hc ________________________________________________________________________ ____ There is no way to peace, peace is the way. -A.J.

Debian install path for Cyclone
by Hans-Christoph Steiner 09 Apr '04

09 Apr '04

In the Debian package, is there any particular reason why cyclone objects are installed into pd/externs/cyclone rather than pd/extra? If they must be in their own directory, couldn't they be moved to pd/extra/cyclone? Then we could get rid of pd/externs directory altogether. .hc http://at.or.at/hans/

Gem Errors
by thewade 09 Apr '04

09 Apr '04

By now we all know that Ive had no end of trouble getting gem to work. When I disable almost everyting from the build, the library loads, but locks up when I try to use any gem objects. When I leave things compiled in, like gltt, the library wont load. /usr/local/lib/pd/extra/Gem.pd_linux: /usr/local/lib/pd/extra/Gem.pd_linux: undefined symbol: _ZN8GLTTFont12setPrecisionEd Where are these errors coming from? When I get home Ill try running gdb on this... Thanks for the help, -thewade

hi I don't know when it got broken, maybe tcl/tk 8.5 has changed ? this line in pd.tk bind $name.c <Alt-Key> {pdtk_canvas_altkey %W %K %A} should be something like if {$pd_nt == 2} { bind $name.c <Option-Key> {pdtk_canvas_altkey %W %K %A} } else{ bind $name.c <Alt-Key> {pdtk_canvas_altkey %W %K %A} } ... gerard

minor bug: patch can open off-screen
by Hans-Christoph Steiner 08 Apr '04

08 Apr '04

This may have already been reported, but I didn't find it. Basically, if a patch has coordinates that are off the screen, it will open fine, it just won't be visible. While this isn't a big deal, when it happens, its confusing. I just spent sometime wondering why my patch wasn't opening, and also not giving any errors. I don't know off-hand, but maybe it wouldn't be to hard to get the current screen size from Tcl/Tk and compare the window placement to that. Any chance of getting access to the bug database so I can report these myself? Or maybe its time to look into bugzilla or sourceforge's bugtracking. .hc ________________________________________________________________________ ____ "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of everyone, and the receiver cannot dispossess himself of it." - Thomas Jefferson

Hello list! I may have gotten it working. THanks for telling me about how dsp only gets called once. I also cleaned up the code a bit as far as casting goes. In the end it came down to getting the nth element if *in by using square brackets instead of using pointer arithmatic. This code should return the Nth element of a sample, though Im still verifying it.

Help with own external
by thewade 07 Apr '04

07 Apr '04

Hello list, I need some help understanding whats going on with my external, and I havent coded in a long time. I appologize if I do newbie things, All I do is try to make the errors go away by trying things. For example I try to cast (t_float *) to (float) for truncf but I get errors unless I make *(t_float *)... Problem 1, Basic functionality. I want to return the Nth sample from a block of samples. Is others have pointed out there may be other ways of doing this using other externals and combonations of objects, but I want to write my own object, in order to both learn more about writing externals, and to have a cleaner solution. Problem 2, Weird errors. I get a werid warning: implicit declaration of function `truncf\' when using a simple math.h function, and if I connect my external to fft~ while enabling a small piece of code I color the FFT~ output. When I then disconnect my object, the fft~ stops putting output out. Problem 1: a closer look. Ive included my code at the bottom of this email. I really appreciate if someone could point out what Im doing wrong. Ive looked at snapshot~ and tried to adopt some of its methods, but it doesnt seem to work when compaired to print~ output. Problem 2: a closer look. The peice of code: int n = (int)(w[3]); t_float *bin = (t_float *)(w[4]); *bin = truncf(*bin); if (*bin > n) *bin = n; if (*bin < 0) *bin = 0; Gives me the error: warning: implicit declaration of function `truncf\'. Im not redefining the function... Also when this piece of code is enabled, and I connect to FFT~ real output I get colored output, then when I break the connection, FFT~ doesnt output anything, it seems. w[3]=sp[0]->s_n - 1 w[4]=&ref->x_bin t_float x_bin; -------------The Code----------------- #include <m_pd.h> #include <math.h> /*-------------------------------------------------------*/ /*fftbin~ */ /* A tool to extract specific bins from the output of */ /* fft~.
