Bonjour,

Et voila, c'est fait et ça marche.
Merci de votre aide à tout les deux.

La démarche :

1 - Redimentionement des partitions sda4 et sda5 sous MSW avec l'outil intégré. Pour contre pour regrouper les espaces non alloués il faut passer par un truc tier !

2 - Création des partitions linux avec gparted depuis le liveUSB. Voir ci-sessous :

# fdisk -l

Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes

3- Installation depuis le liveUSB
avec
- /boot/efi sda1 (partition EFI existante)
- /boot avec sda8
- / avec sda9
- /home sda10
- sda11 comme un espace partagé

Bonne journée à tous

Bonjour,

Je viens de renouveller mon portable que j'avais acquis en décembre 2009. Le nouveau pc est un asus en efi.
Et je n'ai jamais fais d'installation avec ce truc et pour de mauvaises raisons je finalement conserve la
partie M$W.

Le disque qui est formatté comme suit :

# fdisk -l

Disk /dev/sda: 931.5 \GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 25770852-8612-401B-A755-034105F4F9B3

Device Start End Sectors Size Type
/dev/sda1 2048 206847 204800 100M EFI System
/dev/sda2 206848 2050047 1843200 900M Windows recovery environment
/dev/sda3 2050048 2312191 262144 128M Microsoft reserved
/dev/sda4 2312192 783718399 781406208 372.6G Microsoft basic data
/dev/sda5 783718400 1911560191 1127841792 537.8G Microsoft basic data
/dev/sda6 1911560192 1953523711 41963520 20G Windows recovery environment

Pour la partie fedora, je vais récupérer de l'espace disque sur sda4 et sda5 pour faire
la racine / le home / le swap / un disque ext4 avec gparted installé sur un liveUSB.
Jusqu'ici je faisais une aussi une partition /boot, mais si j'ai bien lu avec efi, il me faut monter
la partition sda1 sur le point de montage /boot/EFI.

Si vous pouvez me confirmer ce point c'est cool et merci d'avance.

PS : j'ai hesité pour la licence M$W, et j'avais pris contact avec asus pour le remboursement de licence à cette adresse :
acf_coa@asus.com. Reponse dans la journée avec la procédure de remboursement.

Maintenant compilation du dernier morceau :

cd pulseview/
cmake -DCMAKE_INSTALL_PREFIX=/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib DENABLE_DECODE=y
make
make install
pulseview

Et hop ca marche, trop cool.

Jypaigue, as tu une recommandation de lecture sur le sujet et merci pour ton aide.

Hello,

J'ai fais les ajouts et la correction et c'est cool pour libsigrokdecode.

Un resumé pour etre clair :

export PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:$PATH"
export LD_LIBRARY_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib/pkgconfig:$PKG_CONFIG_PATH"
export C_INCLUDE_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/include:$C_INCLUDE_PATH"
export CPLUS_INCLUDE_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/include:$CPLUS_INCLUDE_PATH"

le controle :

echo $PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/local/sbin:/usr/sbin:/home/laurent/bin

/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib/pkgconfig:
echo $C_INCLUDE_PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:
echo $CPLUS_INCLUDE_PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:

un espace propre et la compilation :

git clone git://sigrok.org/libsigrokdecode
cd libsigrokdecode/

./autogen.sh
./configure --prefix=/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib
make
make install

Maintenant reste pulseview .
Mais je viens d'entendre "T'es pret papa !" donc je vais finir un peu plus tard.
Merci pour ce pas en avnat et à bientôt pour la suite.

Merci du coup de main.
Voici le retour :

On commence par :

export PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:$PATH"
export LD_LIBRARY_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib/pkgconfig:$PKG_CONFIG_PATH"

On contrôle :

echo $PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/local/sbin:/usr/sbin:/home/laurent/bin

echo $LD_LIBRARY_PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib:

echo $PKG_CONFIG_PATH
/datatux/Laurent/test_zone/SIGROK-git/pulseview/siglib/lib/pkgconfig:

Cela semble normal.


La compilation de la bibliothéque :

git clone git://sigrok.org/libsigrokdecode
cd libsigrokdecode/

./autogen.sh
./configure prefix=/datatux/Laurent/test_zone/SIGROK/pulseview-0.1.0/siglib/
make

Dans la console, on a :

Making all in tests
  CC       runtc-runtc.o

Et paf, c'est la bibliothéque installée (/usr/include/libsigrok/libsigrok.h) via le dépôt qui joue pour la compilation.

Les erreurs sont probablement dues à la mauvaise version de bibliothéque.

Bonjour,

Je souhaiterai compiler la version "git" de sigrok (http://sigrok.org/) en locale et à coté de la version disponible dans les dépôts (F18).

Pour cela j'ai plusieurs objets à compiler :
- libsigrok
- libsigrokdecode
- PulseView

Pour la premiere bibliothéque, ca roule.

La compilation se fait avec un

./autogen.sh
./configure
make
make install prefix=/datatux/Laurent/test_zone/SIGROK/pulseview-0.1.0/siglib/

Pour la seconde, j'au un probléme de concurrence entre le bibliothéque libsigrok déjà installée et celle compilée.

La compilation se fait de la même facon que la premiére bibliothéque, mais je ne sais pas comment passer le chemin local.

Si je fais un

./configure --help

J'obtiens en particulier, ce qui semble pouvoir resoudre mon probléme :

  libsigrok_CFLAGS
              C compiler flags for libsigrok, overriding pkg-config
  libsigrok_LIBS
              linker flags for libsigrok, overriding pkg-config

Mais je n'ai pas compris comment les utliser

Ensuite, je vais avoir le même souci avec pulseview qui se compile avec

cmake -DENABLE_DECODE=y
  make

Si vous pouvez me guider, cela serai bien cool, merci d'avance.

Bonsoir,

Pour avoir un comportement normal de ma carte UNO version 1 je suis passé par là :

Bonjour,

Pour l'arduino, regarde les droits sur /run/lock.

Il est possible que ton utilisateur n'a pas les droits suffisants et fais éventuellement un

 chmod 777 /run/lock 

Je fais cela sur mon poste F16 avec une install manuel de l'IDE version 1.

Par defaut, j'ai cela :

drwxr-xr-x. 6 root    root     120  1 mars  08:10 lock

Par contre,
- je ne sais pas si cette manip est bien "propre". Des avis sont les bienvenus !
- cela n'est pas persistant au reboot

Sources :

http://forums.fedoraforum.org/showthread.php?t=280471

Je ne sais pas quel est ton niveau d'utilisation de l'arduino mais regarde le site floss manual, il y a des choses cools sur l'utilisation de LL et entre autre sur arduino

Bonne journée.

Pour XDMP, je suis pas surpris outre mesure. Mais pour avoir utilisé cela en entreprise (solaris/linux) il y a quelques années j'avais plutot un bon souvenir. Cela dit, il y avait une infrastruture matériel et un support système/réseau que je n'ai pas.

Si je comprends bien, tu pense que l'environnement de la machine cliente à une influence ?

J'ai effectivement identifié freenx.
-> J'ai fais un test rapide sans succés.
-> Decouverte du Truc/Tatonnement/Bricole : Je reprend proprement dés que je peut cette semaine.
-> Alors que beaucoup utlise le client de nomachine, j'ai utilisé le client disponible dans les dépôts (freenx-server-0.7.3-23.fc16.x86_64).

Je viens aussi de voir qu'il y a un fil sur le sujet dans le forum. J'arrive dés que possible.

Cependant, il semble que le paquet ne soit pas le plus "uptodate" voir le lien ci-dessous :

J'avais pas forcement mesuré le niveau d'exigence.
Je partais avec l'image de nedit (vi c'est bien mais pas tous les jours) que j'utilise avec un ssh -X via internet.
J'étais d'une part à des kilometres de ce que demande l'opengl et d'autre part j'étais confiant en étant sur un réseau local.

Je viens de tester avec XDMCP.

- modification de /etc/kde/kdm/kdmrc

[Xdmcp]
# Whether KDM should listen to incoming XDMCP requests.  Default is true
Enable=true
#Enable=false

- ajout de l'adresse IP de mon client dans /etc/kde/kdm/Xaccess

- lancement du client vers le serveur

Xorg -terminate -query 192.168.0.14 :1

Cool ça marche mais c'est encore moins fluide et en plus dans ce cas iptraf me donne.



Le besoin en bande passante devient critique dans ce cas.

Reste le premier point de ta suggestion.

A suivre.

Première étape sur les deux postes

# yum install  VirtualGL

Ensuite sur le client-F16, j'ai

et le iptraf-ng




Visuellement, j'ai le même rendu sur les deux machines.
En affichage distant,
- le redimensionnemet de la fenetres glxspheres est lent
- la fenetre ne quitte pas instantanement avec le clic sur la croix (quelques secondes).

En effet, ce qui rend l'utilisation distante pénible, c'est la latente entre les actions sur les menus et les réponses.
Finalement est-ce vraiment un probléme d'affichage ?

J'ai mal formulé les choses.
Effectivement, j'ai un en viron 660FPS avec glxgears mais la fluidité de l'affichage n'est pas celle correspondante.

Boujour,

Merci pour vos indications, je teste cela en fin de journée.

Pour info, quelle est la limite basse pour espérer avoir du déport d'affichage ?

Bonne journée.

Bon je cherche encore, donc toujours de F16 vers F18 avec un ssh -X

Le LIBGL_ALWAYS_INDIRECT élimine sans doutes des problémes et l'utlisation d'une connexion filiaire améliore les choses ce qui me laisse penser que j'ai aussi un souci de bande passante.

On s'approche du jet d'éponge à grand pas

Bonne question, sur le portable F16 j'ai

Est-ce bien cohérent ?

Oups, c'est pas suffisant.

J'ai un peu regardé ailleurs sur ce problème. Il est conseillé de supprimer le /home/laurent/.Xauthority. Je l'ai seulement renommé c'est plus reversible à mon goût.

L'experience donne la chose suivante :
A la premiere reconnexion , j'ai eu un message m'indiquant que le /home/laurent/.Xauthority n'existe pas. Normal

Aprés, j'ai :

$ /usr/bin/glxgears
16 frames in 5.3 seconds =  2.999 FPS
14 frames in 5.3 seconds =  2.633 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server "localhost:10.0"
      after 134 requests (134 known processed) with 0 events remaining.

J'ai peut me connecter mais c'est toujours pas utilisable.

Dans l'autre sens, j'ai toujours :

$ LIBGL_DEBUG=verbose /usr/bin/glxgears
libGL: OpenDriver: trying /usr/lib/dri/nouveau_dri.so
libGL error: failed to authenticate magic 3
libGL error: failed to load driver: nouveau
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
7 frames in 5.2 seconds =  1.358 FPS
15 frames in 5.3 seconds =  2.838 FPS
19 frames in 5.2 seconds =  3.645 FPS
18 frames in 5.2 seconds =  3.460 FPS
18 frames in 5.3 seconds =  3.413 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server "localhost:10.0"
      after 288 requests (288 known processed) with 0 events remaining.

Bon, c'est pas cool ce truc.
