NAME

qdepends - show dependency info  

SYNOPSIS

qdepends <opts> <pkgname>  

DESCRIPTION

The qdepends applet has a couple different modes. Normally it is geared towards answering the queries "what does package X depend on" and "what packages depend on X". Both can further be classified into build, run, and post dependencies.

By default, it will tell you the build time dependencies only (DEPEND).

Currently, qdepends will only query installed packages. There is no support for querying packages not yet installed (the equery(1) tool can do that).

If there is no answer to your query (i.e. you've asked for a package that is not installed, or a version that does not match), then you will get back no output.  

OPTIONS

-d, --depend
Show DEPEND info (default)
-r, --rdepend
Show RDEPEND info
-p, --pdepend
Show PDEPEND info
-k <arg>, --key <arg>
User defined vdb key
-Q <arg>, --query <arg>
Query reverse deps
-N, --name-only
Only show package name
-a, --all
Show all DEPEND info
-f, --format
Pretty format specified depend strings
--root <arg>
Set the ROOT env var
-v, --verbose
Make a lot of noise
-q, --quiet
Tighter output; suppress warnings
-C, --nocolor
Don't output color
-h, --help
Print this help and exit
-V, --version
Print version and exit
 

EXAMPLES

For finding out what a particular package depends on for building, you could do:
        $ qdepends nano
        app-editors/nano-2.3.2: >=sys-libs/ncurses-5.9-r1[unicode] sys-apps/file ...
This tells us that we have app-editors/nano-2.3.2 installed and it depends on ncurses (among other things).
