guile 1.9.7 vs. 1.8.7

guile 1.9.7 vs. 1.8.7

Hi list,

I would like to ask several questions in the terms of new branch.
Maybe I see some bugs or maybe I misunderstand, then apologize.

1. SLIB installation
~~~~~~~~~~~~~~~~~~~~

Information on 

http://www.gnu.org/software/guile/manual/html_node/SLIB-installation.html

doesn't lead to proper slib installation for me. I am using slib3b2
which seems to be installing well this way with 1.8.7. I don't know if
this is bug in guile or slib or it is my fault.

The result is:

2. guile start is slow on my system
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

While guile 1.8.7 is starting less than one second, it takes
approximatelly 12 seconds to start guile 1.9.7 on the same system,
even if I run

GUILE_AUTO_COMPILE=0 guile


3. autocompilation
~~~~~~~~~~~~~~~~~~

When I install and run guile first time, I get the following:

laura:/> guile
;;; note: autocompilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-autocompile argument to disable.

Which seems almost ok, but I am unable to run guile again:

4. Big THANKS
~~~~~~~~~~~~~

Thanks for working for guile! I am not scheme/guile expert, but I am
open for colaboration in this or other context.

Indeed, this expression works with first-class macros in 1.8 but no
longer works in 1.9.  I don’t think 1.9 will ever get support for this
back, so I guess the right solution would be to adapt SLIB’s guile.init.
(This can be done using ‘(cond-expand (guile-2 ...))’.)

Would you like to coordinate with the SLIB maintainer to fix this?

That’s weird.  Are you sure all the .scm files under module/ got
compiled and that the resulting .go files were installed and are in the
search path?

In my experience Guile 1.9 starts faster than 1.8.

It’s a sign that these files weren’t compiled when you built Guile.
Please run ‘make’ again in the build tree.  This should create
module/ice-9/r5rs.go, etc., such that these won’t need to be
auto-compiled when Guile starts.

*This* is a real bug I guess.  :-)

Thanks for your report,
Ludovic.
