[linux-audio-dev] 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

Re: [linux-audio-dev] Re: Advertising Linux Audio

>I looked up some prices for online merchant facilities for the >company I work for and they are not cheap, you have to pay >a monthly fee and some percentage or forfait per transaction. Yes but this percentage would be offset/already paid for by a company that is already running merchant facilities. >You need a relatively high volume merchant site to go with. >(economics of scale). Yes and we definitely have enough people using the software to make small contributions scale correctly. >Is Paypal that bad ? IMO it is another level of red tape that could be bypassed. >I contributed to Ardour through Paypal and in so far I know, >it works. It works but it is not the most effective way of doing things. Users are required to provide a certain amount of information in order to become a payee. The recipient is required to pay a surcharge on every transaction which is higher than the costs imposed by a merchant facility. Both of those work against us when it comes to making it easy for people to contribute funds. I'm interested in the methods that the AGNULA team are using.

[linux-audio-dev] Helpful info for ppl trying to install RH 8.0 (for CCRMA stuff) using Intel 845G chipset (this could be a valuable documentation for others)

by Ivica Bukvic

Hi all, I saw a couple posts on this matter on other lists namely from people who are trying to make multimedia Linux boxes using CCRMA packages and RH 8.0. The issue at hand is that many of the newer machines with cheapo embedded video cards use Intel 845G chipset which is unsupported by RH 8.0's XFree 4.2. However, XFree 4.3 does support it and so the following needs to be done (assumption is that you have a reasonably fast internet connection, otherwise this might prove to be pain -- total d/l amount is approx. 70MB): 1) Install RH 8.0 in command-line mode (graphics mode will most likely fail -- it did on mine, although it might have been partially due to use of an outdated flatscreen monitor that did not allow even the framebuffer mode) 2) Skip XFree config (if you really feel compelled to configure it, do NOT test it, it WILL fail) 3) Upon reboot, using Internet connection, connect to the following ftp in order to retrieve XFree 4.3 version of the x server for the RH 8.0 (you might try the Rawhide mirrors as well but I am not sure whether those will work): ftp://people.redhat.com/mharris/testing/unstable/XFree86 (thanks to Mike Harris from Redhat for making them) 4) Install XFree packages by doing: rpm -Uvh *.rpm --nodeps --force (don't worry it should be ok, at least it was on mine :-) 5) configure up2date 6) run: up2date glibc (you need 2.3.2 for Xfree 4.3, and the one that comes with RH is 2.2.something) 7) Upon finishing installation, run: redhat-config-xfree86 -o /etc/X11/XF86Config (you might need to tinker with the config file, depending on your monitor and other hw) 8) Try starting x server with: startx 9) Now, you should be up and running, but you still need to enable acceleration (since otherwise anything with OpenGL will be simply impossible to use). You need to get the new version of DRI (which reports errors since the kernel module i830.o is ver.1.2 not 1.3 as required by Xfree4.3). So go download new DRI package for 4.3 from here: http://www.xfree86.org/~alanh/linux-drm-4.3.0-kernelsource.tar.gz (big thanks to Leif Delgass for pointing this out) 10) untar the package and make the new module by doing: make -f Makefile.linux 11) install the i830.o file by copying it to the /lib/modules/<kernel-version>/kernel/drivers/char/drm/ (you might wanna backup the old module to something like old-i830.o just in case something screws up) 12) Now reboot the machine and check the /var/log/XFree86.0.log for any DRI errors. You might also wanna run the glxgears or something similar to see if everything is ok. Don't expect much of a fps increase, though (I had 336 fps on the studio's 2.4GHz P4 machine, while with DRI it went up to only 400+ fps). What you will, however, see is the smoother moving the OpenGL window around the desktop and generally better system responsiveness. Now I can even play the Tuxracer at a reasonable framerate. Yay! That's it. Hope someone finds this helpful. Cheers! Ivica Ico Bukvic http://meowing.ccm.uc.edu/~ico

[linux-audio-dev] XAP again - channels, etc.

by Tim Hockin

I fear we've all been very busy. I know I have. I have not had time to devote to XAP, though I have certainly not lost interest. So today I start looking at my evolving spec doc again. The biggest chunk of undecidedness lies in the area of Channels. We never really resolved the Bays/Channels etc debate. We just put it off. Here it is. I'd like to propose the following - it is simple and flexible. Not too confusing. Plugins define 'Modules'. Every plugin has a master Module, and 0-n extra Modules. The host can instantiate Modules as needed. A Module is analogous to a MIDI Channel in a synth (maybe Module is the wrong word). It is analogous to a slot in a mixer. struct XAP_descriptor { ... /* master module descriptor */ XAP_module master; /* other channel descriptors */ int n_modules; XAP_module *modules; /* * Instantiate a module, return a plugin-unique * id/index for it - it's 'Channel'. */ int (*add_module)(void *plugin, int module); /* * Remove a module. */ int (*del_module)(void *plugin, int index); }; struct XAP_module { char *label; char *name; uint32_t flags; /* how many instances of this module are allowed? */ int count_max; /* per-module controls and I/O */ int n_controls; XAP_control **controls; int n_ports; XAP_port **ports; };
