Modeline

This should be the first line of a Portfile. It sets the correct editing options for vim and emacs. See Port Style for more information. Its use is optional and up to the port maintainer.

# -*- coding: utf-8; mode: tcl; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- vim:fenc=utf-8:ft=tcl:et:sw=4:ts=4:sts=4

PortSystem line

This statement is required for all ports.

PortSystem          1.0

Port name

name                rrdtool

Port version

version             1.2.23

Port categories

A port may belong to more than one category, but the first (primary) category should match the directory name in the ports tree where the Portfile is to reside.

categories          net

Platform statement

platforms           darwin

Port maintainers

A port’s maintainers are the people who have agreed to take responsibility for keeping the port up-to-date. The maintainers keyword lists the maintainers' GitHub usernames or email addresses, preferably in the obfuscated form which hides them from spambots. For more, see the full explanation of the maintainers keyword in the Global Keywords section of the Portfile Reference chapter.

Port checksums

The checksums specified in a Portfile are checked with the fetched tarball for security. For the best security, use rmd160 and sha256 checksum types. Checksums should also include the target file’s size.

checksums               rmd160  7bbfce4fecc2a8e1ca081169e70c1a298ab1b75a \
                        sha256  2829fcb7393bac85925090b286b1f9c3cd3fbbf8e7f35796ef4131322509aa53 \
                        size    1061530

To find the correct checksums for a port’s distribution file, follow one of these examples:

%% openssl dgst -rmd160 rrdtool-1.2.23.tar.gz
%% openssl dgst -sha256 rrdtool-1.2.23.tar.gz

RIPEMD160( ... rrdtool-1.2.23.tar.gz)= 7bbfce4fecc2a8e1ca081169e70c1a298ab1b75a

SHA256( ... rrdtool-1.2.23.tar.gz)= 2829fcb7393bac85925090b286b1f9c3cd3fbbf8e7f35796ef4131322509aa53

or update the version in the Portfile:

%% sudo port edit rrdtool

and run:

%% port -v checksum rrdtool

Port dependencies

A port’s dependencies are ports that must be installed before another port is installed.

depends_lib         port:perl5.8 \
                    port:tcl \
                    port:zlib

Port configure arguments (optional)

configure.args      --enable-perl-site-install \
                    --mandir=${prefix}/share/man
