 Posted: Fri Oct 18, 2024 7:40 am Post subject: how to find programms they are only come with useflag X |
 |
|
i have tried to mount something where comes the message unkown filesystem (LVM2_member)
i tried google, found that i have to use vgscan ....
i tried vgs<tab><tab> .... no vgscan here.
i tried emerge -av sys-fs/lvm2
| Code: | | [ebuild R ] sys-fs/lvm2-2.03.22-r5::gentoo USE="readline udev -lvm -sanlock (-selinux) -static -static-libs -systemd -thin -valgrind" 0 KiB |
ok, i was wondering, lvm2 installed, but no vgscan here.
i add "sys-fs/lvm2 lvm" in the file "/etc/portage/package.use"
and run emerge again to build lvm2 new. amd than was vgscan found at my system.
for me, it was a lucky hit to found vgscan now.
how can i find out that program X is only built using useflag X? |

2 my knowledge there is no way to predict what binaries an ebuild generates in general.
No to say depending on USE flags.
However pfl web site may be of some help in some cases, e.g. which ebuild for a required program.
Thks 4 ur attention, interest & support.

| Code: | $ equery u lvm2
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for sys-fs/lvm2-2.03.22-r5:
U I
- - lvm : Build all of LVM2 including daemons and tools like lvchange, not just the device-mapper library (for other packages to use). If your system uses LVM2 for managing disks
and partitions, enable this flag. |

long time ago, i have noticed for me that
in "net-analyzer/dsniff" is the programm "tcpkill" and
in "sys-process/procps" is the program "watch"
but it would be easyer and nice if anyone looking for a programm to find out in what package or useflag the programm is behind |

| The title is misleading, "X" is a USE flag too. |
