Re: [Chicken-users] libsvm egg install problem
Dashi, I messed up. I dumbly used the 'svm-predict' example without creating a model file! So it looks like that is what caused the segfault. I used your other example (svm-train), which was well behaved but gave me the error shown below. I'll try to get some time in the next day or two to create a real dataset and play with it a bit. Looks like it's installed Ok .. Thanks for the help and I'll update you with my results. Tom Error using svm-train example: CHICKEN (c)2008 The Chicken Team (c)2000-2007 Felix L.

We have multiple Makefile-fragments and configure the build via variables set on the command line, for example: make PLATFORM=linux DEBUGBUILD=1 Writing our own makefiles in the end gives us more control.

Felix, I'm almost done with the new make system and compatibilities code for the various supported systems. :) -elf On Tue, 3 Jun 2008, felix winkelmann wrote: On Tue, Jun 3, 2008 at 2:38 AM, Nathan Thern [EMAIL PROTECTED] wrote: Thanks, Felix.
