bug#10557: GUILE_LOAD_PATH variable value ignored when setting %load-path.

bug#10557: GUILE_LOAD_PATH variable value ignored when setting %load-path.

[Ian Hulin]

This doesn't appear to work as per page 41, section 4.2.2 Environment
Variables in the docs. Strangely enough, though settings of
GUILE_LOAD_COMPILED_PATH *are* observed and added to the front of
%load-compiled-path.

Cheers,
Ian Hulin

Err, all you have done here is show that GUILE_LOAD_COMPILED_PATH has no
bearing on %load-path, which is perfectly in accordance with the
documentation as far as I can see.

As for the question of GUILE_LOAD_PATH not prepending to %load-path, I
can't reproduce this on a recent stable-2.0 with fedora 16.

[ian@Kagami ~]$ env GUILE_LOAD_PATH=notadir guile -q
GNU Guile 2.0.3.155-6f0e5
...<snip>...
scheme@(guile-user)> %load-path
$1 = ("notadir" "/usr/local/share/guile/2.0" "/usr/local/share/guile/site/2.0" "/usr/local/share/guile/site" "/usr/local/share/guile")
scheme@(guile-user)> 

I'll report back again after I've built the 2.0.3 release

scheme@(guile-user)> %load-path

$2 = ("notadir2" "/usr/local/lib/guile/2.0/ccache" "/usr/local/lib/guile/2.0/site-ccache")

As you can see, I get the same behaviour on 2.0.3

Hi Ian,

I think I agree with ijp's assessment of things.  If you can point to
something in the manual that is confusing in this regard, please let us
know.  Thanks!

Andy
