Starting up gives me Illegal Instruction

Installation & Configuration Linux
#1

I installed from slackware package at linuxpackages.net, sorted out a few dependency problems, but when I run ardour I get this message:

Illegal instruction

Any ideas of what this could be or how I can get more info about the problem?

#2

you will need to use a debugger (i.e. gdb). if you don’t know how to use a debugger, there is no way you can get more information about the problem. its not really acceptable that a packaged version of ardour does this.

#3

gdb doesn’t provide much in the way of info:

Program received signal SIGILL, Illegal instruction.

A backtrace just repeats last line

I also tried compiling 0.99.2 from source but get these errors:

Solved

#5

Could you post the solution to the problem for others who might have a similar problem?

#6

The problem was me: after downloading the various libraries that Ardour needs I installed them all, but somehow missed out libsndfile :slight_smile:

#7

Some Linux distributions package ardour after compiling it to use MMX and/or SSE instructions. If you run such a package on a processor with no MMX and/or SSE support, you will see “Illegal Instruction”. I consider this a mistake by the packagers, and it should be reported if this is what is happening to you.
