Evaluate Dependencies

Use the pkgdepend(1) command to automatically generate dependencies for the package. The generated depend actions are defined in Depend Actions and discussed further in Chapter 4, Specifying Package Dependencies.

Dependency generation is composed of two separate steps:

1. Dependency generation. Determine the files on which the software depends. Use the pkgdepend generate command.

2. Dependency resolution. Determine the packages that contain those files on which the software depends. Use the pkgdepend resolve command.

Generate Package Dependencies

Some manually declared dependencies might be necessary if pkgdepend is unable to determine dependencies completely. In such a case, you should add explanatory comments to the manifest.

In the following command, the -m option causes pkgdepend to include the entire manifest in its output. The -d option passes the proto directory to the command.

$ pkgdepend generate -md proto mypkg.p5m.2 | pkgfmt > mypkg.p5m.3

The output mypkg.p5m.3 file has the following content. The pkgdepend utility added notations about a dependency on libc.so.1 by both mylib.so.1 and mycmd. The internal dependency between mycmd and mylib.so.1 is silently omitted.

set name=pkg.fmri value=mypkg@1.0,5.11-0
set name=pkg.summary value="This is an example package"
set name=pkg.description \
    value="This is a full description of all the interesting attributes of this 
example package."
set name=info.classification \
    value=org.opensolaris.category.2008:Applications/Accessories
set name=variant.arch value=i386
dir  path=opt/mysoftware owner=root group=bin mode=0755
dir  path=opt/mysoftware/bin owner=root group=bin mode=0755
file opt/mysoftware/bin/mycmd path=opt/mysoftware/bin/mycmd owner=root \
    group=bin mode=0644
dir  path=opt/mysoftware/lib owner=root group=bin mode=0755
file opt/mysoftware/lib/mylib.so.1 path=opt/mysoftware/lib/mylib.so.1 \
    owner=root group=bin mode=0644
dir  path=opt/mysoftware/man owner=root group=bin mode=0755
dir  path=opt/mysoftware/man/man1 owner=root group=bin mode=0755
file opt/mysoftware/man/man1/mycmd.1 path=opt/mysoftware/man/man1/mycmd.1 \
    owner=root group=bin mode=0644
link path=usr/share/man/index.d/mysoftware target=/opt/mysoftware/man
depend fmri=__TBD pkg.debug.depend.file=libc.so.1 \
    pkg.debug.depend.reason=opt/mysoftware/bin/mycmd \
    pkg.debug.depend.type=elf type=require pkg.debug.depend.path=lib \
    pkg.debug.depend.path=opt/mysoftware/lib pkg.debug.depend.path=usr/lib
depend fmri=__TBD pkg.debug.depend.file=libc.so.1 \
    pkg.debug.depend.reason=opt/mysoftware/lib/mylib.so.1 \
    pkg.debug.depend.type=elf type=require pkg.debug.depend.path=lib \
    pkg.debug.depend.path=usr/lib

Resolve Package Dependencies

To resolve dependencies, pkgdepend examines the packages currently installed in the image used for building the software. By default, pkgdepend puts its output in mypkg.p5m.3.res. This step takes a while to run since it loads a large amount of information about the system on which it is running. The pkgdepend utility can resolve many packages at once if you want to amortize this time over all packages. Running pkgdepend on one package at a time is not time efficient.

$ pkgdepend resolve -m mypkg.p5m.3

When this completes, the output mypkg.p5m.3.res file contains the following content. The pkgdepend utility has converted the notation about the file dependency on libc.so.1 to a package dependency on pkg:/system/library, which delivers that file.

set name=pkg.summary value="This is an example package"

    value="This is a full description of all the interesting attributes of this 
example package."
