Re: [Faudiostream-users] Reading a ~.pd_linux with Pure Data
Hi Hugo, Sorry to hear you've had problem with my instructions. I would say it could be the cause of the incorrect .pd_linux files, since in my case, after installing llvm and clang flawlessly via ubuntu repository (apt-get), I could not make the faust2puredata output correct files. The way I've found was to uninstall llvm and clang and build them like I've shown you. Concerning your error, I've found several topics you should look at. Honestly I've not dived deep into the subject but I think this one could work for exemplehttp://sohanikh.blogspot.fr/2013/02/how-to-build-llvm-from-source-on-ubuntu.html . Hope it will work this time. Good luck! Thomas 2014-05-12 23:53 GMT+02:00 Hugo Caracalla es.illus...@gmail.com: Thanks to both of you. Julius, I ran the .pd you sent me : it works perfectly fine on Pure Data, no problem outputting the sound. Henceforth my problem must be coming from Faust and nothing else, that's a big step. I will try to reinstall Faust cleanly once I get some sleep, see if this helps. Thomas, I did what you advised me to : everything runs fine except for one error (and I fear it is no small one). When I try to do : ./configure --enable-shared --enable-optimized --enable-targets=host-only The process get stuck at : configure: error: Selected compiler could not find or parse C++ standard library headers. Rerun with CC=c-compiler CXX=c++-compiler ./configure ... Which from what I understand is a compiler path problem. I assume that llvm and clang didn't get installed properly : could this maybe be the cause of the incorrect .pd_linux files ?

I actually didn't know that faust2puredata existed : since it outputs both a .pd and a ~.pd_linux file, does this mean that there was no need for the whole installation of pure and faust2pd ? I ran it on noise.dsp, but the two files I obtain have exactly the same problem as before : .pd_linux is unreadable and .pd is messily read, with the same messages. Could this come from me mis-installing Faust ? -Hugo On 12 May 2014 18:24, Julius Smith j...@ccrma.stanford.edu wrote: Hi Hugo, Did you try the faust2puredata script? (I personally wish faust2puredata were renamed to faust2pd with the existing faust2pd renamed to faust2pdpure or something like that.) - Julius At 10:10 AM 5/12/2014, Hugo Caracalla wrote: Hello, Firstly, I have to say that I am a mere beginner both in audio signal processing and in Faust : hence, my apologies if I missed an obvious point along the way. I am trying to run a function created in Faust (here I will use noise.dsp as given in the examples) with Pure Data (extended). To do so I created a .pd_linux file, which I understand is a library for Pure Data, by typing this : faust -a puredata.cpp -o noise-pd.cpp noise.dsp g++ -DPD -Wall -g -shared -Dmydsp=noise \ -I/usr/include/pdextended \ -o noise~.pd_linux noise-pd.cpp The problem is, my .pd_linux file is not recognized by Pd-extended : Ignoring '/home/hugo/Desktop/noise~.pd_linux': doesn't look like a Pd-file I tried to get around the problem by installing faust2pd, which I understand is able to create objects in Pure Data, which are simpler to use. So I installed Pure-lang and its dependencies needed by faust2pd (apart from the midi one, with which I am still happily wrestling). Faust2pd seems to work, meaning if I run : faust2pd noise.xml.dsp with the xml I extracted from noise.dsp, I obtain noise.pd, that puredata can run. But then Pure Data says : faust-control $0 ... couldn't create noise.pd 5 1 7 0 (noise~-outlet) connection failed noise~: no method for '/noise/Volume' noise~: no method for 'active' Which seems to handicap quite a bit noise.pd since I can't get a sound of it. My basic guess would be that what makes noise~.pd_linux unreadable also makes noise.pd problematic, but I fear I can't go any further. I have been trying for a week to get the whole path from Faust to Pure working, and I am quite disheartened to see all my efforts go into this instead of going into the making of my actual Faust function. So if any amongst you thinks he has a lead on this matter, I would be truly grateful to you. Sincerely, Hugo

Re: [Faudiostream-users] faust2pd make error
Hi Hugo, The issue you describe is with the llc from LLVM 3.4, cf. http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-February/069979.html. It's a Linux-specific bug (well, it might also affect Windows, I haven't checked that yet, but llc 3.4 works fine on the Mac at least). The bug breaks Pure's batch compiler which is used to compile the faust2pd.pure script to a native executable. I've been meaning to file a bug report at the LLVM Bugzilla so that this gets fixed in LLVM 3.5 at least, but totally forgot about it. Thanks for reminding me. :) I'll check whether that bug is still present in the latest LLVM revision from svn and file a bug report asap if it is. If you want to stick to LLVM 3.4, the easiest way to work around the bug is to just use the llc and opt tools from LLVM 3.3 instead, see this thread on the Pure mailing list: https://groups.google.com/forum/#!topic/pure-lang/ZiMK5DY9Tq0. They will work fine even if Pure itself is linked against the LLVM 3.4 libraries. If you're running the latest Pure version, you can compile LLVM 3.3 with --disable-shared and drop the statically linked llc and opt executables into the Pure library directory (/usr/lib/pure or /usr/local/lib/pure, depending on where you installed Pure). Or you can try to use the ready-made Linux ELF 64 and 32 bit binaries available here: https://bitbucket.org/purelang/pure-lang/downloads/llvm-3.3-tools.tar.bz2. They will hopefully work on all Linux distributions with recent C/C++ libraries. The package also contains a README with instructions on how to compile your own llc and opt if the provided binaries don't work on your system. Which Linux distribution do you use? For Arch Linux and derivatives we have a package which implements this workaround, so you could install Pure straight from the AUR and you'll be set. If you're on some other distribution, drop me an email so that I can walk you through the needed steps, if necessary. Sorry for the hassle. It's really not Pure's fault. The LLVM devs broke their tools on Linux and didn't even notice it. :( Alas, this kind of breakage happens much too often. E.g., on the Mac the llc from LLVM 3.3 was broken. But there's really no alternative to LLVM these days, if you need a comprehensive cross-platform compiler backend featuring JIT compilation, so we compiler writers love LLVM despite its bugs. :) Albert On Wed, May 14, 2014 at 3:46 AM, Hugo Caracalla es.illus...@gmail.comwrote: Hello, Trying to keep it all as clean as possible, I did the steps Thomas gave and managed to get quite further : The installation of llvm, Clang, their dependencies, Pure, pd-Pure, and purexml went smoothly.
