Hello,
I have NLopt 2.4.2, and I'm trying to run the example in the tutorial
under Guile 1.8.8.
First, I had to modify the example slightly, to deal with LD_LIBRARY_PATH:
(setenv "LD_LIBRARY_PATH" "/opt/nlopt/lib")
(use-modules (nlopt))
(define (fx x grad)
(if grad
(begin
(vector-set! grad 0 0.0)
(vector-set! grad 1 (/ 0.5 (sqrt (vector-ref x 1))))))
(sqrt (vector-ref x 1)))
....
Second, I invoke guile as "guile -L /opt/nlopt/share/guile/site" so it
can find nlopt.scm.
But the result is the following error:
guile>
Backtrace:
In unknown file:
?: 0* [primitive-load "/usr/home/ko/projects/nlopt/ex.scm"]
In /usr/home/ko/projects/nlopt/ex.scm:
