I know that when you spin a potentiometer full right or left, it connects its middle leg to 5V or ground, but never had problems with it.

I managed to install Pd with apt-get. Any idea why there's no space to compile from source but can install from the repos? well, the puredata package will be considerably smaller than the build-process (which also contains a large number of intermediate binary files; and the resulting binary is not (yet) stripped of uneeded symbols. e.g. if i install Pd on my debian system using the puredata package it will take about 5.7MB, whereas if i build it myself the pd directory contains about 34MB of data (after the build; not counting the 20MB in the .git directory which i expect not to be there when using the tarball) A possible scenario would be that there was enough space to install Pd from the repository, but later there was not enough space left for compiling Pd. Either way, it's moot to further investigate the reason, since the reason is clear: Your filesystem is full, as IOhannes clearly stated before. The only way to deal with that is to free some space deleting files or moving them to another partition or storage device. I've only installed libtool, automake and jack before I tried to compile Pd. Everything else that's in the filesystem came with the image installed in the eMMC module. Any suggestions as to what I should delete? anything you don't need... (it's hard to answer this without being too snarky). since you only installed so few things, it seems that you are using a pre-made system image. probably the image comes with a number of fancy software installed, including a full fledged desktop environment (like gnome), an office suite (like libreoffice) and what not. check what you have, think what you will never use and throw it away. in the meantime, you might want to start thinking about why you have an 8GB disk and you only see 3.5GB (on two partitions). - - maybe you are not using the emmc module at all - - maybe there is a large unused/unpartioned space on the emmc module. - - maybe you bought an 8GB module but only got a 4GB one. in any case, check $ cat /proc/partitions I started a new thread about a new error message I get when I tried to run Pd, which is: i'll come to that in the other thread then. fgmasdr IOhannes -BEGIN PGP SIGNATURE- Version: GnuPG v1 iQIcBAEBCAAGBQJUBazJAAoJELZQGcR/ejb4bQQP/1qtscYa036tWjbgdZemWN+j D6QD65+86kHiGSueXlm5AJaoY4mvqXZcyW0NbGHEDoTjmtsv/W24gk17USGs7Vas bQSwTCv1QQ0u1u9U9Uaw4jbFSlCBxccox1j5WTKvHEIDt/ek1QpSQ0xnA4L3aLVK FHjxpmAvGabYJqQ0BWcdc/Ymcx5OXDpcHfiVoNWVFhiCwF9Ru7ZW/U4n8jM5Z5lG 1Y/YX7a80//LTMKbQ8HcUYPm4sf0D0iKfvYsQv+U4YVO7GhYGAvdwl0F9NeR3qrc jLAkaLStLYPCaK3f06JlFqFrxTEVHlLXId9C3D4zg9jUh587afwDI3vp6WrfyofW mHNqDmaHv3gUf6me0EMetbZSbQksc7oFdRKRSJvD/2+H8Zea/IB9c7dnxMOZD+4U I3DC4ZXZhkI49iQhZZQJo5qatQNYnad39LWbt11xnf272uSj4Dywq6r6xu55xtTJ mdRL9jSvxMOcR5jY6+iuRwrNpqlJ5+q5r2vR/brhQRKUx7rkQiM+5lKiAvGgXMh4 8drBoHlYzzotLFD7yVGZpimOAqS4+0Z2bGoK3dU7qlFw3j6kzT4kXzFwFDrWXL2f QobBwoAtrXE5/H8VAb/YYI2BVXSCz7BYIGUXutUUsQrDQPkRkWMAQOeE1LppHW5L mPTDcwgUMekyN3fWtDnh =19Wa -END PGP SIGNATURE- ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

An update to this thread. I found this thread in Odroid's forum http://forum.odroid.com/viewtopic.php?f=79t=5650 and followed the suggestion of the fourth post, saying to change the 'Option fbdev /dev/fb1' to fb0 (well it's for Debian Wheezy and my Odroid is running in Ubuntu, but gave it a shot), and when I try to open Pd I get this: xcb_connection_has_error() returned true priority 6 scheduling enabled. priority 8 scheduling enabled. application-specific initialization failed: couldn't connect to display localhost:10.0 but I don't get the X11 connection rejected because of wrong authentication. error any more.
