Bugzilla Bug 164127

To build autogen-5.8.8, guile has to be compiled with deprecated (+discouraged
or guile don't compile) and result in
a segfault of autogen during build: 
make[4]: Entering directory
`/var/tmp/portage/sys-devel/autogen-5.8.8/work/autogen-5.8.8/getdefs'
top_builddir=.. top_srcdir=.. PATH=`cd ../columns >/dev/null && pwd`:$PATH ;
export top_builddir top_srcdir PATH ;
/var/tmp/portage/sys-devel/autogen-5.8.8/work/autogen-5.8.8/agen5/autogen
-L../autoopts ./opts.def
AutoGen aborting on signal 11 (Segmentation fault) in state DONE
processing template >

       for function Text (17)

/var/tmp/portage/sys-devel/autogen-5.8.8/work/autogen-5.8.8/agen5/autogen
-L../autoopts ./opts.def
make[4]: *** [opts.h] Error 134

Btw, this is working with guile-1.8.1 (with borked econfigure)

Reproducible: Always

Steps to Reproduce:
1. emerge guile with +deprecated and +discouraged
2. emerge autogen
3. profit!

Actual Results:  
AutoGen aborting on signal 11 (Segmentation fault) in state DONE

Expected Results:  
Autogen merged

Created an attachment (id=108319) [edit]
Patch to guile ebuild

This patch allowed me to compile guile and autogen without segfault

btw, some version (after patched guile emerge):
# emerge guile autogen -pv

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] dev-scheme/guile-1.8.1-r2  USE="deprecated discouraged nls
-debug -debug-freelist -debug-malloc -elisp -networking -regex -threads" 0 kB
[1] 
[ebuild   R   ] sys-devel/autogen-5.8.8  0 kB 

Total: 2 packages (2 reinstalls), Size of downloads: 0 kB
Portage overlays:
 [1] /usr/local/portage

so autogen needs to make sure guile is built with USE="discouraged deprecated
-threads" ?

*** Bug 164206 has been marked as a duplicate of this bug. ***

I forgot a '\' in guile-1.8.1 ebuild causing almost all econf options to be
ignored. This caused (among others) deprecated, discouraged and threads to be
on regardless of use flags.

Pierre's patch is wrong. The config option is "--with-threads". By effectively
removing it, threads are built by default regardless of use flag.

Thx to point out, didn't look that far: so it means guile without thread don't
work well since autogen will segfault (and possibly others)

side note: typo in autogen-5.8.8 --> dec-scheme instead if dev-scheme
!!! ERROR: sys-devel/autogen-5.8.8 failed.

the typo was fixed sometime ago

so what is the combination autogen needs ?  USE="deprecated discouraged
threads" ?

discouraged is now implied by deprecated, see bug 164206.

Just tested -r1: correct flags should be "+deprecated +threads" and it works
fine

Just I have some doubt for other packages: This will work for autogen but I
don't have a clue for other package using a -thread guile: They may start to
segfault as well

No matter if I set deprecated and/or threads or nothinh as extra USE flag,
guile-1.8.1-r1 won't compile right.

Just to be sure, did you also set +discouraged (Looks like the change didn't
hit your ebuild) since if found these def's in discouraged and deprecated
files:

guile-1.8.1 $ find . -iname \*.[ch] | xargs grep -H SCM_SYMBOLP
./libguile/discouraged.h:#define SCM_SYMBOLP scm_is_symbol
./libguile/deprecated.c:  if (SCM_SYMBOLP (obj))
./libguile/deprecated.c:  if (SCM_SYMBOLP (obj))
./libguile/deprecated.h:#define SCM_XEVALCAR(x, env) (SCM_SYMBOLP (SCM_CAR (x))
and
guile-1.8.1 $ find . -iname \*.[ch] | xargs grep -H scm_keyword_dash_symbol
./libguile/discouraged.c:SCM_DEFINE (scm_keyword_dash_symbol,
"keyword-dash-symbol", 1, 0, 0, 
./libguile/discouraged.c:#define FUNC_NAME s_scm_keyword_dash_symbol
./libguile/discouraged.h:SCM_API SCM scm_keyword_dash_symbol (SCM keyword);
./libguile/deprecated.c:  return scm_keyword_dash_symbol (keyword);

It indeed seems that change didn't hit my ebuild yet. Adding discouraged solved
the problem. Thanks :)

autogen ebuild now checks those flags as well
