 |
|
Ciao tutti,
j'essaie d'installer "dev-util/systemtap". Bon, d'abord il manquait une option dans le kernel, que j'ai rajoutée. Je recompile, y tout y tout, je suis sur le "nouveau" kernel, maintenant j'ai un:
| Code: | # emerge systemtap
Calculating dependencies... done!
>>> Emerging (1 of 1) dev-util/systemtap-20060325 to /
>>> checking ebuild checksums ;-)
>>> checking auxfile checksums ;-)
>>> checking miscfile checksums ;-)
>>> checking systemtap-20060325.tar.bz2 ;-)
* systemtap needs CONFIG_RELAYFS_FS in the kernel
* enable it under Filesystems -> Pseudo filesystems -> Relayfs.
!!! ERROR: dev-util/systemtap-20060325 failed.
Call stack:
ebuild.sh, line 1555: Called dyn_setup
ebuild.sh, line 668: Called pkg_setup
systemtap-20060325.ebuild, line 29: Called die
!!! CONFIG_RELAYFS_FS not present
!!! If you need support, post the topmost build error, and the call stack if relevant. |
Bon, le hic c'est que ce CONFIG_RELAYFS_FS n'existe pas !
| Code: | # grep CONFIG_RELAY* /usr/src/linux/.config
CONFIG_RELAY=y
|
Il n'y a qu'un CONFIG_RELAY (que j'ai mis à yes d'ailleurs)...
Si vous avez une idée, merci

salut, c'est dans les sources du kernel : | Code: | cd /usr/src/linux
make menuconfig
/relayfs |
et tu verras où modifier
(à vue de nez, ce sera dans "filesystems" / "pseudo-filesystems")
EDIT: en effet, c'est ce que dit le message d'erreur 
EDIT2: tu as kel quernel ? il se peut que tu n'aies pas le patch "relayfs" ?

J'ai le gentoo-sources 2.6.17-r8 actuellement... parce qu'il faut patcher ? huh !
EDIT: sur le site: http://www.opersys.com/relayfs/index.html y'a rien qui correspond à cette version de kernel :/

C'est tout ce que j'ai...
EDIT:
j'ai trouvé ça:
| Code: | Hi,
As discussed last week, I've made some changes to the runtime allowing
bulk mode (-b option) when using CONFIG_RELAY (kernel >= 2.6.17) to
store the relay files in debugfs rather than their current location in
/proc. Before I check them in though, I wanted to make sure nobody
sees any problems in doing this.
This change only affects systemtap running on systems with kernels >=
2.6.17 - for older kernels, the older CONFIG_RELAYFS runtime code is
used as usual, and debugfs isn't needed. The bottom line is that in
order to use bulk mode with kernels >= 2.6.17, you need to have
CONFIG_DEBUG_FS turned on in the kernel. For reference, debugfs is
turned on by default on Fedora kernels and SLES10 (but since SLES10
uses a 2.6.16 kernel, it doesn't really matter at this point).
