Hello,

I am trying this on Slackware 14.2 (64-bit) OS. 

I get this error message:

/home/anand/octave/control-3.1.0/x86_64-slackware-linux-gnu-api-v52/__control_slicot_functions__.oct: failed to load: /home/anand/octave/control-3.1.0/x86_64-slackware-linux-gnu-api-v52/__control_slicot_functions__.oct:undefined symbol: dgegs_

error: called from

I am unable to find the reason for this.

Any clues to correct this?

Thanks for your hellp.

The error "undefined symbol: dgegs_" looks like something is wrong with LAPACK on your system.  I don't know anything about Slackware, but are all those dependencies BLAS, LAPACK, ... correctly installed?  Are binaries of Octave available, that you installed on your system and how did you obtain the control package you are using?

HTH,

Kai

Hello,

Thank you so much for your email. I have installed Octave, BLAS and LAPACK using the build scripts taken from SlackBuilds.org.

BLAS BuildScript

LAPACK BuildScript

GNU Octave Build Script

Octave is running properly.

I am still unable to correct this.

With regards,

Anand

Alright, and how did you install the control package?  What was/is the output of

   >> pkg install -forge control
