pix_blob y-value: bug?
by Max Neupert 17 Mar '04

17 Mar '04

Oops, the workaround: * -1 (instead + -1) --- The y-value of the pix_blob symbol seems to be inverted (it gives out data from 1-0 instead of from 0-1, meaning 0.7 instead of 0.3). Is that a bug? workaround: | -1 | + -1 | max

Id have to do some weird sed trick in the configure script and then reattach the -Wl,-shared for the rest of the configure script, and that seems like trouble to me. I guess that Im not that fimiliar with shell scripting to do that. LIBS=echo $LIBS | sed s/\\-Wl\\,\\-shared// then LIBS=$LIBS -Wl,-shared ? > you could also try the \"--enable-static\" flag for the configure (on my machine > it then fails to find the the GL-libraries -- so maybe...) I not too fimiliar with what static versus shared means, but it seems like static would introduce more toubles like below. > i have never tried to link Gem only statically against all the libraries > needed. > on my system it fails (but i have nvidia\'s openGL-drivers which are > dynamic only). > and of course, you will have to build gem again once you want > hw-acceleration... Im not sure how to set up hardware acceleration. I read that openGL comes with Xfree86 and that ati has special drivers, but not for my rage 128 (i think thats what this old Dell i8000 has). Is theres some way to replace libstdc++ with something else, like g++ or something? Are there some environment variables I can set that would clear this up? Could I downgrade gcc for this build, would that help? rpm -I --old-package Thanks for the speedy reply! -thewade

Gem Reduction CVS compile error
by thewade 16 Mar '04

16 Mar '04

I need some help. As as we all have become painfully aware, I have not been able to compile Gem. I need to be shut up, and to thoes ends I am asking for some debugging help. Heres the situation. The configure script for Gem (Gem/src/Gnu/configure) tries to compile the following as an attempt to detect -lGL: gcc -o conftest -g -O2 -L/usr/X11R6/lib conftest.c -lGL -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 1>&5 And fails. When I try to compile removing the -Wl,-shared portion of the line I get success. What does this mean? I cannot remove this flag from the configure script because then the build will fail, right? In short, If I trick the configure script to passing this portion, then will the build fail later? My versions of compilers: gcc-3.3.3-2.1 libstdc++-3.3.3-2.1 These are all that Gem needs right? is there anything else that I could install that might fix this problem? Thanks for your help, To help this meager and humble linux initiate, -thewade

ok a stupid question
by Adrian deCleir 16 Mar '04

16 Mar '04

this is a real beginner question but i cant see it in the help files to creat a symbol I make message box and write (symbol 123456) By doing this, $1 represents 123456 anywhere in my programme so how do I make a new variable?? As in how can I have maybe $2(or anything) represent a new number like 56789?

couple of questions (take your pick)
by chris tyrrell 16 Mar '04

16 Mar '04

hmmmmm does anyone know anything about pdvst and logic? it seems to crash my logic 5 (does it even work for logic 5?) but i find logic 5 tempermental anyway... also i cant seem to get pd to run the grantab and sIgpAck libraries, anyone have any similar problems with these guys (im running windows me) also does anyone know of any resources or texts dealing with the compiling and command line stuff on pd? i find it a little frustrating that i cant find any texts or tutorials that are concerned directly with pd.... anyway thanks for any help...it would be more than useful.... ===== ___________________________________________________________ Yahoo!

amplitude overload
by Oded Ben-Tal 16 Mar '04

16 Mar '04

I'm encountering some strange behaviour. I'm running PD on linux (rh9 planetcCRMA) using maudio quattro sound card. It worked fine yesterday, but today I get amplitude overload and some errors. The test audio is distorted and I had to reduce the amplidute by factor of 10 in a patch I was working on to get acceptable levels. I'm using jack: jackstart -d alsa -d hw:1,0 -r 44100 which complains (semi periodically): *** alsa_pcm: xrun of at least {8.732-30} msecs I ran the exact same thing yesterday with no (noticeble) problems and I haven't changed anything since.

Jpegs + pixel co-ordinates
by Alyte Podvoiskis 16 Mar '04

16 Mar '04

I've created a graphics window from which it is easy and quick to get mouse-cursor co-ordinates. As soon as I render a Jpeg to the window its takes an age for the co-ordinates to arrive. Is this to do with me using pix_draw??? What can I use instead, without applying texture because I only want to work in 2-D, and I want to display the image at the same time as getting the co-ordinates. Alyte
