Re: error messages of "dynamic-link"

[tantalum]

I found out that the libraries which do not work contain a different 
kind of content:
for example (complete file):
/* GNU ld script
  Use the shared library, but some functions are only in
  the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-i386)
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a  AS_NEEDED ( 
/lib/ld-linux.so.2 ) )

or

INPUT ( %{_libdir}/libopcodes.a -lbfd )


I ran a script containing only the dynamic-link call, as root.
following is output of strace:

access("/lib/libc.so", R_OK)            = -1 ENOENT (No such file or 
directory)

Hi Julian,

A couple of ideas to try:

1. Rerun under strace, to find out exactly where Guile is looking for
the library that you want.

2. Check that permissions on the library files will allow the user
running Guile to read them.

If that doesn't solve the problem, please post the part of the strace
output which covers looking for the problematic library.

Regards,
       Neil
