Re: I get unknown immediate error in guile 1.7

[Roland Orre]

I solved the problem. It seems as linking (at least for me) is not done
in the right way for modules, neither for 1.6 or 1.7. Explanation below.

The problem showed to be that guile loaded wrong libraries, which was
caused by the the correct library files not having been created. Guile
had been reading wrong libguilereadline.la all the time. I noticed this
when I deinstalled the (debian distributed) guile-1.6. Then the
libguilereadline.la library was not found for my locally compiled
guile-1.6 either, despite that I had included both
/usr/local/guile/guile-1.6.0/lib
/usr/local/guile/guile-1.6.0/guile-readline in the LTDL_LIBRARY_PATH.

I then relinked the readline.o file under guile-readline with
the settings I use for my own modules, then it worked. The make
script is at the end. The correct guile-1.6 libguilereadline
file was read and the same procedure worked for guile-1.7 as well.
The problem probably has to do with the guile-readline autogen.sh
but how this script works is above my head.

The fundamental problem seems to be that the installation linking
is not done in the right way. None of the .la files under the
lib directory (${exec_prefix}/lib) contains any library references.
Observe that I used the name "libgreadline" in the script.

Here are the error messages given.
After a normal make install, where LTDL library is set as:
export LTDL_LIBRARY_PATH=/usr/local/guile/guile-1.7/lib

I get the following (empty) error message:
  /usr/local/guile/guile-1.7/guile/1.7/ice-9/readline.scm:38:5:
  In procedure dynamic-link in expression 
  (load-extension "libguilereadline" "scm_init_readline"):
  /usr/local/guile/guile-1.7/guile/1.7/ice-9/readline.scm:38:5:
  file: "libguilereadline", message: ""

If I then also include /usr/local/guile/guile-1.7/guile-readline
first in the LTDL path, then I get the following error message:
 /usr/local/guile/guile-1.7/guile/1.7/ice-9/readline.scm:38:5:
 In procedure dynamic-link in expression
 (load-extension "libguilereadline" "scm_init_readline"):
 /usr/local/guile/guile-1.7/guile/1.7/ice-9/readline.scm:38:5:
 file: "libguilereadline", message: "|o\"@à Ì\x11\x08readline.a:
 cannot open shared object file: No such file or directory"

If I then run the make script below under guile-readline then
it works. This newly created .la files contains library references
to the .so files created under .libs. 
I also included my configuration parameters below.

Have I done anything obviously wrong in the configuration?
