disclaimer: this is only general advice, i don't have a leapmotion nor ever used the external in question. - properly link leapmotion.pd_linux against libLeap.so if you do $ ldd leapmotion.pd_linux | grep -i leap you should see a line containing "libLeap.so" - make sure that the libLeap.so library can be found by the runtime linker. you can see that it is not found properly, if the above cmdline gives you something like: libLeap.so => not found there are two ways to fix this: - either use the environment variable LD_LIBRARY_PATH to point to the path where libLeap.so is liven before starting Pd (this is a hack; if possible do not use it; it's also very similar to what you already have) - install libLeap.so into a place that is searched automatically by your linker (e.g. /usr/local/lib) the second one is obviously preferred. if - for whatever reasons - you want to keep using an evnironment variable, you could create a wrapper script, that you run instead of the actual Pd-binary, and which set's up the envvar: #!/bin/sh LD_LIBRARY_PATH=/path/to/my/leap-library/ /usr/bin/pd $@ if your actual Pd-binary is /usr/bin/pd (as installed by the Debian packages, e.g. on ubuntu), you could even call this script "pd" and put it into "/usr/local/bin" (requires root). if you then type "pd" on the cmdline, it will call the script from /usr/local which in turn calls the binary in /usr/bin... gfmds IOhannes
