load-extension woes

load-extension woes

[Paul Emsley]

Hi, 

I have a few questions, here is the first:

I am trying to follow the reference manual, but I can't get
load-extension to work:


$ setenv LTDL_LIBRARY_PATH $HOME/guile/lib
$ ls $LTDL_LIBRARY_PATH/libguile-bessel.so 
   8 /home/paule/guile/lib/libguile-bessel.so*
$ guile
guile> (load-extension "libguile-bessel" "init_bessel")
<unnamed port>:1:1: In procedure dynamic-link in expression
(load-extension "libguile-bessel" "init_bessel"):
<unnamed port>:1:1: file: "libguile-bessel", message: "file not found"
ABORT: (misc-error)

Type "(backtrace)" to get more information or "(debug)" to enter the
debugger.

However, if I expand the library name:
maybelline ~/Projects/mapview/src> guile
$ guile
guile> (load-extension "/home/paule/guile/lib/libguile-bessel.so"
"init_bessel")

That works...

What am I doing wrong?

Cheers, 

Paul.

(using 1.6.0 built myself on RedHat 7.3)

This is probably be a bug in libltdl.  Try configuring guile with
"--enable-ltdl-install" and reinstalling it.

Guile 1.6.1 will fix this.  You can get a preview from CVS or here:

For the record, I could not get 1.6.0 to work having configured it with
"--enable-ltdl-install".  Howver, the snapshot did indeed work.

Thanks,

Paul.
