Time to time everyone figures out that there is an unavailable package in the standard Gentoo repository (portage). Therefore, it comes useful to extend the repository with portage overlays (e.g., with layman). What if this does not work either? It’s time to create your own ebuild.
There exists a complex how-to. However, the brief info is as follows. Once updated the /etc/make.conf with:
And integrate the new package in the package tree. For instance:
mkdir /usr/local/portage/dev-python mkdir /usr/local/portage/dev-python/python-xklavier
In each package, the following four files are necessary (the ebuild name is an example):
The ChangeLog file contains the brief information about the package changes. The Manifest file contains several rows referencing all files (four in this case) including their size (in Bytes) and respective checksums (using RMD160, SHA1, and SHA256 functions). The structure of Metadata.xml file can be as follows:
no-herd email@example.com Package description
The structure of the own ebuild can be found here or copied from any other package in the system (/usr/portage directory).
To calculate the checksums (for the Manifest file), the following commands can be applied:
openssl dgst -ripemd160 python-xklavier-0.4.tar.gz sha1sum python-xklavier-0.4.tar.gz sha256sum python-xklavier-0.4.tar.gz
Alternatively use the Whirlpool method:
openssl dgst -whirlpool python-xklavier-0.4.tar.gz
