 Posted: Wed Jul 31, 2024 5:18 pm Post subject: FIXED: Verständnisfrage zum USE Flag "utils" |
 |
|
Ich habe ein Verständnisproblem bei den USE Flags.
Es geht um das flag "utils". Dieses ist nicht global gesetzt:
| Code: |
emerge --info | grep -i utils
app-misc/pax-utils: 1.3.7::gentoo
sys-devel/binutils: 2.42-r1::gentoo
sys-devel/binutils-config: 5.5::gentoo
|
Ebenso ist "utils" nicht unter /etc/portage/package.use/ als USE flag zu finden:
| Code: |
find /etc/portage/package.use/ -type f -exec grep "utils" {} +
/etc/portage/package.use/x86_64-pc-linux-gnu:>=dev-libs/elfutils-0.158 static-libs
/etc/portage/package.use/x86_64-pc-linux-gnu:>=app-arch/xz-utils-5.4.2 static-libs
/etc/portage/package.use/x86_64-pc-linux-gnu:# required by media-tv/v4l-utils-1.26::gentoo
/etc/portage/package.use/cross-avr:cross-avr/binutils cxx multilib
|
Trotzdem wird media-libs/libv4l mit dem Flag "utils" installiert:
| Code: |
emerge -pv media-libs/libv4l
These are the packages that would be merged, in order:
Calculating dependencies... done!
Dependency resolution took 2.06 s (backtrack: 0/20).
[ebuild R ] media-libs/libv4l-1.26.1::gentoo USE="bpf jpeg qt5 utils -doc -dvb -tracer" ABI_X86="32 (64) (-x32)" 0 KiB
Total: 1 package (1 reinstall), Size of downloads: 0 KiB
|
Warum wird media-libs/libv4l mit USE="utils" installiert wenn nirgendwo das Flag gesetzt ist?

Ich denke, ich habe die Lösung gefunden:
| Code: |
cat /usr/portage/media-libs/libv4l/libv4l-1.26.1.ebuild | grep IUSE
IUSE="bpf doc dvb jpeg qt5 tracer +utils"
|
"utils" ist ein IUSE-Default. Das kannte ich bisher noch nicht. Wieder was gelernt.
Entschuldigt, dass ich dieses gepostet habe. Ich hatte keine Ahnung, dass es IUSE flags gibt. Erst die KI hat mich darauf gebracht.
