Hello everybody! Since it is not possible to install Pure Data Extended from the repository using the simple apt-get command I've tried to compile it following a mix of guides online and I'd like to share with you how I made it! :x This procedure should works with PD-Extended 0.43.4 on Ubuntu 12.04 (downloadable here: https://sourceforge.net/projects/ud...tu_img/udoo_quad_ubuntu1204_v2.0.zip/download) First of all you need to install all the requested dependencies using this command: Code: sudo apt-get install fakeroot ttf-dejavu libfftw3-dev libspeex-dev libvorbis-dev libflac-dev libsndfile1-dev libsamplerate0-dev libgavl-dev libmad0-dev dssi-dev liblo-dev flite1-dev libtk-img tcllib swig tcl8.5-dev tk8.5-dev liblua5.1-0-dev subversion git rsync automake libgsl0-dbg libgsl0-dev libgsl0ldbl gsl-bin libgsl-ruby libgsl-ruby libranlip-dev octave-gsl oggvideotools slang-gsl yorick-yeti-gsl xorg-dev libglu1-mesa-dev autoconf libfftw3-dev liblua5.1-0-dev swig libvorbis-dev ladspa-sdk libspeex-dev libmp3lame-dev lua5.1 tcl-dev dpkg-dev build-essential devscripts build-essential After that you have to download the source code from here: http://sourceforge.net/projects/pur....4/Pd-extended_0.43.4-source.tar.bz2/download in a folder of your choice, for example ~/Download Now you can unzip the archive using the command: Code: cd ~/Download tar jxf Pd-extended_0.43.4-source.tar.bz2 Then you have to compile all stuff using: Code: cd pd-extended/packages/linux_make make install It will takes about one hour or more (I've been playing to "The Stanley Parable" while it was compiling... So I don't exactly how long does it take ) If everything has worked correctly (i.e.: no error in the last lines of the shell) you can create the DEB package using: Code: make package It will take about 5 minutes, after that you can finally install it with: Code: sudo dpkg -i Pd-0.43.4-extended.deb Now you can launch it from the Gnome interface, you can find it under "Applications->Sounds->Pd-extended"! I've tested using an external speaker connected to the RCA output (so no test via HDMI) and I noticed that, the first time I've launched it, it freezes for few seconds, then I went on "Media->Audio Settings" changed the "Sample Rate" to 48000 and select as input and output device "vt1613-audio (hardware)". Honestly I didn't test everything, but for sure the audio output is working and so far this enough for me. I will try to make GEM working, but I think it will be harder!
