Re: guile can't find dynamically loaded library

[Michael Vanier]

Well, it's even more hosed that you realize :-(  When I do what you say, it
reports that it can't find libguile-bessel.so in /usr/lib.  When I copy
libguile-bessel.so into /usr/lib, it reports that it can't find it in
/usr/local/lib (the next path in my LD_LIBRARY_PATH).  And so forth.  When
I manually set my LD_LIBRARY_PATH to just /usr/lib, it complains that it
can't find libguile-bessel.so in /lib. It seems to be impossible to make it
happy.  Output looks like this:

guile> (load-extension "libguile-bessel.so" "init_bessel")
standard input:1:1: In procedure dynamic-link in expression (load-extension 
"libguile-bessel.so" "init_bessel"):
standard input:1:1: file: "libguile-bessel.so", message: 
"/lib/libguile-bessel.so: cannot open shared object file: No such file or 
directory"
ABORT: (misc-error)

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


Thanks for your help,

Mike
