Execute the file /lib/libc.so.6, it will tell you its version. I don't know a way to look up the Version of your installed Header-Files from glibc, maybe you can ask your Package-Manager. Anyway, your Headers and Librarys MUST match ! > I tried building the static version, but then I get the following error: > g++ -o Gem.pd_linux -L/usr/X11R6/lib -L../../../GemLibs/liborb ../Manips/*.o > ../Particles/*.o ../Base/*.o ../MarkEx/*.o ../Pixes/*.o ../Controls/*.o > ../Nongeos/*.o ../Geos/*.o ../openGL/*.o -shared -lquicktime -lmpeg3 -lorb > -lglib -lgltt -lttf -ljpeg -ltiff -lpng -lglut -lGLU -lGL -Wl,-Bstatic -lz > -lm -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 > /usr/bin/ld: cannot find -lgcc_s > collect2: ld returned 1 exit status Your gcc was configured with "--enable-shared" to use a shared libgcc (called libgcc_s; only used for C++), but can't find it. See below Also you dont really try to build the static version, as -shared -Wl,-shared -Wl,-export-dynamic shows. > I then checked > ld -lgcc_s > > And the only thing I got was: > ld: warning: cannot find entry symbol _start; not setting start address > Now, could someone please tell me what the heck does this mean???

But > /usr/bin/ld: cannot find -lgcc_s says, that he can't find it ? Very strange ... Try to alter the specs-file from your gcc, it should be in the syme location as libgcc.a (try gcc --print-libgcc-file-name). The specs file contains a line like *libgcc: -lgcc replace -lgcc with the following line "%{!shared:-lgcc} %{shared:/usr/lib/libgcc_s.so}" (only valid for gcc3, i don't know if older gcc's use the same Syntax !!) In case of an accident (the file is very sensible with spaces) you can reconstruct the original specfile with gcc -dumpspecs > specs; or simply delete the file, gcc has a copy of it built in. You my also have a look in the linker-scripts from ld, there location depends on the configuration binutils, search for elf_i386*. Then look if the SEARCH_DIR-Entrys includes "/usr/lib". But the best thing you could do to solve your Problem is to reinstall your glibc, glibc-devel, gcc, g++ and binutils-packages, when this does not not help, consider switching to another distribution ...

[linux-audio-user] iCubeX experiences?

by j.c.w.

greetings all! i am a bit of a controller freak and have just started looking into the iCubeX system (http://www.infusionsystems.com/index.shtml). i used to roll all of my own control devices, but i am a bit short on time as of late (full time jobs tend to do that). i'd like to give this thing a chance. i see that paul davis (you rock, dude) wrote a gnu/linux editor for the device that controls a limited subset of its features, but it looks like the software hasn't been touched for some time. i am interested in using it with pd primarily and possibly jmax. my question is this: does anyone out there have any experience to share with me re: using this gadget with gnu/linux /only/. i don't do windows at home, so i'd like to know what i can expect. anywho, enough of that...so, anyone know anything about this doo-dad? thanks! j.c.w.

[linux-audio-user] Needing help in resolving the Pd-Gem package linker problem (and hopefully learn something in the process :-)

by Ivica Bukvic

Hi all, This is the issue I've been dealing with for the past couple of hours. I am using mostly vanilla Mdk 9.0. I am trying to compile Gem from source (for Pd), and while it does compile without any problems at runtime (pd -lib Gem) I get the following issue: /usr/lib/pd/extra/Gem.pd_linux: /usr/lib/pd/extra/Gem.pd_linux: undefined symbol: __ctype_toupper_loc /usr/lib/pd/extra/Gem: can't load library I've tracked this one to the gcc library (please correct me if I am wrong). However, there are no errors at compile time: g++ -o Gem.pd_linux -L/usr/X11R6/lib -L../../../GemLibs/liborb ../Manips/*.o ../Particles/*.o ../Base/*.o ../MarkEx/*.o ../Pixes/*.o ../Controls/*.o ../Nongeos/*.o ../Geos/*.o ../openGL/*.o -shared -lquicktime -lmpeg3 -lorb -lglib -lgltt -lttf -ljpeg -ltiff -lpng -lglut -lGLU -lGL -lz -lm -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 I also tried adding all over the place -lgcc like this: g++ -o Gem.pd_linux -L/usr/X11R6/lib -L../../../GemLibs/liborb ../Manips/*.o ../Particles/*.o ../Base/*.o ../MarkEx/*.o ../Pixes/*.o ../Controls/*.o ../Nongeos/*.o ../Geos/*.o ../openGL/*.o -shared -lgcc -lquicktime -lmpeg3 -lorb -lglib -lgltt -lttf -ljpeg -ltiff -lpng -lglut -lGLU -lGL -lz -lm -Wl,-shared -lgcc -Wl,-export-dynamic -lgcc -lXxf86vm -lXext -lX11 and the compile is successful, but I still keep getting the same error. I tried building the static version, but then I get the following error: g++ -o Gem.pd_linux -L/usr/X11R6/lib -L../../../GemLibs/liborb ../Manips/*.o ../Particles/*.o ../Base/*.o ../MarkEx/*.o ../Pixes/*.o ../Controls/*.o ../Nongeos/*.o ../Geos/*.o ../openGL/*.o -shared -lquicktime -lmpeg3 -lorb -lglib -lgltt -lttf -ljpeg -ltiff -lpng -lglut -lGLU -lGL -Wl,-Bstatic -lz -lm -Wl,-shared -Wl,-export-dynamic -lXxf86vm -lXext -lX11 /usr/bin/ld: cannot find -lgcc_s collect2: ld returned 1 exit status make: *** [Gem.pd_linux] Error 1 I then checked ld -lgcc_s And the only thing I got was: ld: warning: cannot find entry symbol _start; not setting start address Now, could someone please tell me what the heck does this mean??? ldd /usr/lib/libgcc_s.so gives: libc.so.6 => /lib/i686/libc.so.6 (0x4001a000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) At this point, I am confused and do not know what to do. I tried upgrading ldconfig, ld, and am currently recompiling gcc from a cooker source (which is taking a lot of time). So, I would greatly appreciate any help I can get on this issue, since the whole idea of linking is not so clear to me. Finally, I would appreciate the explanation of -Bstatic flag which seems to invoke -lgcc_s that is subsequently not found for whatever reason, despite the fact the ld otherwise finds it (with the aforementioned warning though). Any help on this issue is greatly appreciated! Sincerely, Ico

[linux-audio-user] Help with mixer/preamp config (OT?)

by Bryan Koschmann - GKT

Hello, I'm am sure this is off topic but I am desparately seeking help. I am trying to figure out how the mixer/preamp/input card will coincide with each other. If I have a card with 4 inputs (either midiman digital or SB lives), I will be needing preamps. I looked at the M-Audio Audio Buddy, which seems like it simply has 2 XLR inputs and 2 1/4" outputs. That part is straightforward and I understand. However, I was looking at mixers and I got lost. I looked at a Eurorack (cant remember which model) for around $170. It had 4 XLR inputs, and the box said it had 4 mic preamp inputs. But, how do the outputs work? I was looking for 4 1/4" jacks marked "output 1" "output 2" and so forth. Where am I lost? Please forgive me for asking such newbie questions. I simply do not know where else to turn. I've searched the net high and low and didn't find the answers. Thank you very much in advance, Bryan

[linux-audio-user] Announcing Audio* Music Synthesis Project

by Nick

Hello, I am new to this list, so please be gentle, and help me learn to use it. I am announcing my project I have going on at SourceForge. http://audiostar.sourceforge.net http://www.sourceforge.net/project/audiostar The project is about creating real-time synthesis applications. It targets to run on Linux and Windows, but with an emphasis to getting the most out of Linux. Audio* is a toolkit library of synthesis classes in C++ for creating instruments and applications that make computer music. So far it has been mostly concentrated on the only application so far, Mojo, an Analog Modelling Synthesizer similar to Rebirth but more flexible than a 303 which tries to emulate classic synthesizer sounds of the 70's and 80's. So far everything is in one big mess, and I am using KDevelop Studio as I learn more about the Linux programming tools (I am coming from several years of Windows programming, but little Unix background). The project uses FLTK (because it's fast, light, and stupidly simple to use). One project is to create a unified set of FLTK widgets specifically for Audio programming (and probably port them to use GTK and other widget libraries). So far I am using Port Audio as the sound library, it works well. I don't have plans to create yet another low level sound driver unless it is something many people would find useful. The only application is the Mojo, and like I said, it's a Rebirth like program but much more flexible and different (and doesn't really sound like it either). It does have nice alias-free waveform generation though of classic Analog waveforms, and some half-decent filters I designed. I hope to find people interested in using it, or helping work on it, or make this project grow into something cool. At least, I'd like to get feedback. People on sourceforge don't send any feedback at all. It would be nice to have just a small community of people interested in it's development and using it and letting me know what is going on. Thanks

[linux-audio-user] PlanetCCRMA - RealPlayer -artsd problems

by Dave Phillips

Greetings: I installed RealPlayer on a machine running RH 8.0 and PlanetCCRMA. At first it worked fine, but now it gets the following error on startup under KDE : SNDCTL_DSP_SETFMT failed Cannot allocate memory Anyone know how to resolve the problem ? Is artsd the culprit here ? RealPlayer also complains that another application has the sound device. Weird: this machine has a SBLive installed with the PlanetC ALSA drivers, I don't understand why RealPlayer complains about not being able to access the device. So, how do I check to see who's hogging the resources ? Best regards, == Dave Phillips The Book Of Linux Music & Sound at http://www.nostarch.com/lms.htm The Linux Soundapps Site at http://linux-sound.org

[linux-audio-user] Audio file format

by Robert Epprecht

I have found a CD with audio files and would like to know what format they are. (I know very little about different audio formats, sorry.) The label on the CD says they are MP3, but the files have names like 1.wav 2.wav mp3blaster 1.wav Bad sound file format. cp 1.wav /tmp/1.mp3 mp3blaster /tmp/1.mp3 Sound device control error. play 1.wav playing 1.wav ('play' plays the file and considering it's duration it is much too long to be a normal .wav file, IMHO) file 1.wav 1.wav: RIFF (little-endian) data, WAVE audio, Microsoft ADPCM, mono 44100 Hz I thought WAVE was a format without compression? The duration of the files (when played by 'play') shows that this is not possible. So what is it? BTW: The file (loaded like a text file in emacs ;-) starts with RIFFBä^BWAVEfmt 2 (where ^B is *one* byte) Thank you for sharing your knowledge, Robert

[linux-audio-user] Multiple soundcards

by Bryan Koschmann - GKT

Hello, I'm looking at (for now) utilizing the SB 128PCI's I have laying around and doing 3 of those for input and 1 SB Live Value for midi and output. Any recommendations against that, or thoughts that an SB 16 PCI would be better? I have access to a few of those as well. As I said in my posts awhile back, I have 2 instrument mics, 1 vocal mic, and a keyboard with midi. The mics are all XLR with 1/4" (transformers?). Will I be needing any preamps/mixer for these? If so any recommendations for something with 3 mic preamps? I apoligize for all the questions. I'm quite new to the audio world and have only ever had real user experience with Soundforge on a win98 box :) I'm looking forward to some hardcore stuff once I learn. Thanks! Bryan

[linux-audio-user] ALSA 0.9.1 on IBM ThinkPad T20

by Greg Reddin

Hey all, I'm sort of a Linux newbie. I've been using Linux pretty much exclusively for a little over a month. I've used and developed on Unix for several years, so much of it is familiar to me. Anyway, I got ALSA up and running fine on my desktop machine, but am having problems with my laptop. I searched the web for days and can't seem to find consistent information, so I wonder if you guys could help. My laptop is an IBM Thinkpad T20 with a "Cirrus Logic CS-4614/22/24 CrystalClear SoundFusion Audio Accelerator" soundcard. I'm running a fairly "vanilla" installation of RedHat 8.0, meaning I didn't reconfigure the kernel or anything like that. The kernel version is 2.4.18-14. The OSS driver for cs46xx was installed, and I believe the sound test worked during installation. But since then, audio has not worked at all. XMMS will play,and you can see the meters popping, but no sound comes out of the speakers or headphones. I downloaded the ALSA 0.9.1 tarballs and ran through the installations. The first problem I ran into was unresolved symbols due to symbol versioning in the kernel. I fixed that by adding the following to the alsa-driver Makefile: ifdef CONFIG_MODVERSIONS CPPFLAGS += -include /usr/src/linux-2.4.18-14/include/linux/modversions.h endif So, I did a make clean, reran the ./configure, make, make install, ./snddevices, and installed alsa-lib and alsa-util. At some point I had to rmmod the cs46xx OSS driver because it complained that it was in use. I also chmod'ed the /dev files as the doc suggested. I used gnome-alsamixer to unmute the channels and set levels. At first alsaplayer would play a file (.wav or .mp3) and the meters would show activity, but no sound would be present. Now, when I try to run alsaplayer, play, or xmms I get an error message that says "Cannot open device: /dev/dsp". So has anyone gotten ALSA 0.9.1 to work on this kernel? Should I use a different ALSA package or a different kernel? Any suggestions would be greatly appreciated. Thanks, Greg Reddin __________________________________________________ Do you Yahoo!? Yahoo!
