80be6ca4 1## DPorts background:
3Dports is an effort to use FreeBSD’s ports system as a base for DragonFly, and the pkg tool as a way to manage binary packages built from DPorts. This is complicated, so I’ll explain each part in order.
5FreeBSD ports are a FreeBSD-specific collection of software installation files that automate building 3rd-party software on FreeBSD. You’ve probably already heard of them. (Note there’s no mention of DragonFly.)
7DPorts is a collection of files that map to existing FreeBSD ports, and contain any changes necessary to make that port also build on DragonFly. Many of those programs build without changes on DragonFly. DPorts builds from source.
9pkg is used for package management, and is usable on FreeBSD, PC-BSD, and on DragonFly. The binary packages produced from building with DPorts can be installed from remote locations and managed separately using pkg, so that software upgrades and installation can be performed with binaries only. (It’s much faster that way.)
11Every port seen in DPorts is known to build on DragonFly. A port is added only after it builds successfully, using poudriere as a bulk software tool. Ports are only updated to a newer version when that newer version builds, too, so once something arrives in DPorts, it should never break from being updated at some point in the future.
13## Installing DPorts:
15To use DPorts, you need two things:
17*First thing:* DragonFly 3.3 or later,.
19*Second thing:* You need to rename /usr/pkg so that your existing pkgsrc binary programs don’t get accidentally used while working with DPorts, causing confusion. If anything goes wrong with DPorts when you are installing it and you want to go back, remove all the DPorts packages and rename /usr/pkg back to normal. (Don’t confuse pkg, the management tool, with /usr/pkg, the normal installation directory for pkgsrc. ) For the installation of the base port files:
21 cd /usr
22 make dports-create-shallow
24If you’ve already renamed your /usr/pkg directory, git won’t be in your path any more. You can instead download a tarball and unpack it, which also happens to be possible automatically via that same Makefile.
26 cd /usr
27 make dports-download
29Downloading via git is fastest, so if you do need to use the tarball via make dports-download, build devel/git, delete /usr/dports, and then pull it again with make dports-create-shallow. This all comes from [John Marino’s Github site for DPorts](https://github.com/jrmarino/DPorts/#readme).
31## Managing DPorts
33DPorts doesn’t use pkg_info, pkg_add, and the other tools traditionally seen on DragonFly for pkgsrc. Instead, package management is done with pkg. Use pkg info, pkg install, pkg remove, and pkg update to list, install, delete, and upgrade various packages on your system. Packages built from source or downloaded as prebuilt binaries are managed the same way, using these tools.
35See some of the [other](https://mebsd.com/make-build-your-freebsd-word/pkgng-first-look-at-freebsds-new-package-manager.html) [writing](http://ivoras.net/blog/tree/2012-07-26.pkgng---best-thing-since-sliced-bread!.html) about pkg for FreeBSD for details on how it works.
37Since DPorts doesn’t update a package until it gets a successful build, and installations are of successfully built binary packages, upgrades with prebuilt packages should always succeed. Since they’re binary, they should be fast. There’s a lot of ‘shoulds’ in this sentence, but these are reasonable suppositions.
39## Building from source
41Building from source works similar to ports and pkgsrc: cd into the appropriate program's directory, and type 'make'. 'make install' to install the software, 'make clean' to clean up work files, and so on. Set BATCH=yes to take all default package options without checking. Use 'make config-recursive' if you want to set all the port's options, and the options of its dependencies, immediately instead of during the build.
43Note that this is only necessary if you want to build from source with a non-default config, or if you don't have a binary repository available to pull files from with pkg.
45## Installing binaries
47The pkg tool can be used to install packages, manage them, and so on, as mentioned previously. DragonFly as of this writing does not pre-set a repository to pull packages from; this will change in the future.
49## What about pkgsrc?
51Pkgsrc and DPorts shouldn’t be used at the same time, since one system’s packages may be at different versions but still get picked up during building for the other system. That’s about it for restrictions.
53DPorts is brand new so the normal caveats apply; don’t install it on a mission-critical machine, and be ready to deal with any surprises from using it if you do try it out.
55## What packages are available?
57Browsing the Github repo will show you all listed packages. It changes as more packages are built. Changes from DragonFly builds are sometimes relevant to the original FreeBSD port, so there’s benefits for everyone here.
59## What next?
61This is experimental; this will not necessarily replace pkgsrc. It's available in this release for further testing and feedback. Remember, this is a new project, so a willingness to deal with problems and contribute to fixes is necessary.
