[gentoo-user] Python and man problems

Hello all,

I encounter some problems with python compiling and man errors.

1- Python :

I can't emerge some python packages (ie pyorbit, libmpeg2, 
libbonobo-python, etc...).
Even the installed python packages can't emerge anymore.
Here is the error message for libgnome-python-2.28.1-r1
(USE="-examples" PYTHON_TARGETS="-python2_7%")

*ERROR: dev-python/libgnome-python-2.28.1-r1::gentoo failed (configure 
phase):
  *   No supported Python implementation in PYTHON_TARGETS.
  *
  * Call stack:
  *     ebuild.sh, line   93:  Called src_configure
  *   environment, line 4118:  Called gnome-python-common-r1_src_configure
  *   environment, line 2078:  Called python_parallel_foreach_impl 
'gnome2_src_configure' '--disable-allbindings' '--enable-gnome' 
'--enable-gnomeui'
  *   environment, line 3947:  Called _python_obtain_impls
  *   environment, line  702:  Called _python_validate_useflags
  *   environment, line  758:  Called die
  * The specific snippet of code:
  *       die "No supported Python implementation in PYTHON_TARGETS."
*

Is it a locale problem ?

Here is my /etc/env.d/02locale

LANG=fr_FR.utf8
LC_ALL=""

When i run locale, i get :

$ locale
LANG=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"

LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=

2- man does not work anymore ; i get the error message :

ie : $man emerge (sorry, it's in french)

*man emerge
sh: most : commande introuvable
Erreur pendant l'ex�cution du formatage ou de l'affichage.
Le syst�me retourne pour (cd "/usr/share/man" && (echo ".ll 11.1i"; echo

| /usr/bin/gtbl | /usr/bin/nroff -mandoc | most) l'erreur 127.
Il n'y a pas de page de manuel pour emerge.
*
I recompiled the sys-apps/man package with success but the error is 
still there.

My configuration :

$emerge --info

Your PYTHON_TARGETS setting does not make sense. If you want python 
modules to target python-2.7 then define:

PYTHON_TARGETS="python2_7"

Otherwise, define "python3.3" (or even both, space separated).

As above.

You can make it English by prefixing the command with LC_MESSAGES=C.

most ... command not found. I've never heard of such a command. It looks 
as though PAGER="most" is defined in your environment. In Gentoo, it is 
normally set as "/usr/bin/less".

It transpires that sys-apps/most is in portage. Emerging this package 
should fix it, if you intend to continue using it as the PAGER.

As far as your first problem goes, libgnome-python requires python2_7:
grep COMPAT libgnome-python-2.28.1-r1.ebuild
PYTHON_COMPAT=( python2_7 )

The output you supplied indicates that python2_7 is disabled for this
particular package, i.e. 'PYTHON_TARGETS="-python2_7%".

The default base profile on my stytem has:
grep ^PYTHON_TARGETS /usr/portage/profiles/base/make.defaults
PYTHON_TARGETS="python2_7 python3_3"

emerge --info output on your system seems to be the same as well.

Looks like on your system, you have python2_7 disabled somewhere. Do you
have PYTHON_TARGETS redefined in /etc/portage/make.conf?

For the package in question you need to have python2_7 enabled.

As for your second problem, as has already been pointed out, you seem to
be using a PAGER that is not currently found on your system.
Here's the man debugging output I get on my system:
man -d emerge 2>&1|sed '/bzip2/,$!d'
  (cd "/usr/share/man" && (echo ".pl 11i"; /bin/bzip2 -c -d
'/usr/share/man/man1/emerge.1.bz2') | /usr/bin/gtbl | /usr/bin/nroff
-mandoc | /usr/bin/less)

Hope this helps.

most is the best manpager I've found found - the default syntax highlighting is perfect for man pages.

You don't have to make it your default pager, you can set it separately:

$ env | grep -i page
PAGER=/usr/bin/less
MANPAGER=/usr/bin/most
$

Thanks for the tip! I hadn't come across `most`, and now since you
pointed to it I've set it as my global MANPAGER.

Cheers ;)

Hello all,

Thank you very much for your help: problems solved.

-PYTHON_TARGETS="python2_7" are now defined
-PAGER="most" is defined in your environment: Icompiled it again.
Now man emerge works.

Well, I'm now quite quiet...until next problem !!!
Thank you again
Cheers
Roger

I haven't followed this thread up to now, but are you setting this yourself in 
make.conf? It shouldn't be necessary: all packages that rely on python set 
their own targets - and they're best left that way too. If you twiddle with 
your targets yourself, sooner or later you'll find yourself having to 
disentangle a cat's cradle.

$ grep -i python /etc/portage/make.conf
$

I too was grateful for the tip about most. Thanks, Stroller.

It' not in make.conf.
Your remark is judicious   ;-)

Hi,
does anybody know how to tell 'most' to scroll when I use my mouse  
wheel?

Many thanks for a hint,
Helmut

IIRC it's KDE which does it for me : Most runs in a Konsole.

I'm using icewm where my mouse wheel generates button4/5 events.
Is there a general means to teach X11 to map mouse button events to key  
codes?

Thanks,
Helmut

Hello,

I use Terminator with XFCE and scroll works fine with mouse wheel.

Cheers,

Some terminals do, some don't.  AFAIK it is not configurable in each case, but 
if anyone know how to get to work with urxvt please share.
