Hi guys,

i was trying to build guile 2.0.6 from tarball and from the latest
revision and get with both a similar error like these:
https://lists.gnu.org/archive/html/bug-guile/2011-03/msg00111.html
https://lists.gnu.org/archive/html/bug-guile/2011-12/msg00058.html
https://lists.gnu.org/archive/html/bug-guile/2012-07/msg00005.html

For me it looks like this on Trisquel 6.0 (beta):

  GEN      guile-procedures.texi
Throw without catch before boot:
Throw to key misc-error with args ("primitive-load-path" "Unable to find
file ~S in load path" ("ice-9/boot-9") #f)Aborting.

Btw the autogen.sh file is missing in the 2.0.6 tarball.
If you need any further information please let me know.

Hi,

DNS <dns@rbose.org> skribis:

>   GEN      guile-procedures.texi

The problem here is that ice-9/boot-9.scm, which is an essential
start-up file, could not be found.  I don’t see any reason why this
would happen.

Are you building a pristine 2.0.6, with no distro patches etc.?

Can you confirm that the file module/ice-9/boot-9.scm is available in
your source tree?

Can you run ‘strace -f -o log make’, and send the output of
‘grep ice-9/boot-9 log’?

Thanks,
Ludo’.

Heya,

sorry for my late reply, and thx a lot for your help.
i was compiling 2.0.7 and had the same issue, then i was finally lookin
at the log and figured out that it is because of a "umlaut" char in the
parent directory-name where i tried to build guile.
The directory was called "Arbeitsfläche" ("desktop" in german) and in
the log i saw the files could not be found because the dir-name was not
correctly converted (into UTF-8 i guess). The dir name was shown as
"Arbeitsf??che"...

Btw i uploaded 2.0.7 packages to the GNU PPA @ launchpad
https://launchpad.net/~dns/+archive/gnu/+packages?field.name_filter=guile-2.0&field.status_filter=published&field.series_filter=

Best regards,
DNS

Ooh, I see.  This is related to commit ed4c3739 (see
<http://lists.gnu.org/archive/html/guile-devel/2011-12/msg00160.html>).

What happens is that the directory name may be correctly decoded when
passed as an argument:

--8<---------------cut here---------------start------------->8---
[ludo@pluto:~/tmp/Courtès]$ strace -f -o ,,s ~/src/guile/meta/guile -L $PWD -c '(set-port-encoding! (current-output-port) "UTF-8")(pk %load-path)'

;;; (("/home/ludo/tmp/Courtès" ...))
--8<---------------cut here---------------end--------------->8---

But then ‘scm_stat’ calls ‘scm_to_locale_string’, which uses the wrong
encoding at this point, leading to this:

--8<---------------cut here---------------start------------->8---
[ludo@pluto:~/tmp/Courtès]$ strace -f -o ,,s ~/src/guile/meta/guile -L $PWD -c '(use-modules (t))'

[...]

ERROR: In procedure scm-error:

24237 stat("/home/ludo/tmp/Court?s/t.scm", 0x7fff16fda150) = -1 ENOENT (No such file or directory)
24237 stat("/home/ludo/tmp/Court?s/t", 0x7fff16fda150) = -1 ENOENT (No such file or directory)
--8<---------------cut here---------------end--------------->8---

The problem is even worse when the directory is passed through an
environment variable, because in that case even the input decoding is
broken:

--8<---------------cut here---------------start------------->8---
[ludo@pluto:~/tmp/Courtès]$ GUILE_LOAD_PATH=$PWD:... ~/src/guile/meta/guile -c '(set-port-encoding! (current-output-port) "UTF-8")(pk %load-path)'

;;; (("/home/ludo/src/guile/guile-readline" "/home/ludo/src/guile/module" "/home/ludo/tmp/Court??s"))
--8<---------------cut here---------------end--------------->8---

Ouch!

So, as mentioned in the thread above, 2.2 will not have this problem.
But for 2.0, I can’t even imagine an ugly hack that would help.

Thoughts?

Ludo’.

Nice debugging for a nasty problem.

What about an environment variable that can tell Guile to do the
setlocale().  We can set the environment variable during the build so
that at least the build works, and whisper it to users when they run
into problems (while noting that the variable will not be read in 2.2).

Or should we go ahead and document it, and simply have its default value
change between 2.0 and 2.2?

Yes, sounds like a plan.  ‘GUILE_INSTALL_LOCALE’?

Yes, even better, since the setlocale change will have to be documented
at least in NEWS anyway.

Are you willing to look into it?

Sure.  I have some local patches that I will push when I next get a net
connection.
