Package Dependencies Required to Build Samba/Building Samba on Gentoo
Building Samba on Gentoo
Please note that the following sections assume at least an intermediate understanding of the Gentoo packaging system.
Gentoo uses Python 3 as the default python interpreter, but at this time Samba requires Python 2 (2.4.2 or later). The following set of commands will install and set up Python 2 as the default python interpreter.
# emerge --ask --noreplace '<dev-lang/python-3' # eselect python set python2.7 # python-updater
On Gentoo, you have two choices for a kerberos implementation, app-crypt/mit-krb5 and app-crypt/heimdal. Unfortunately the two implementations can not be installed at the same time. Currently, the Samba only supports app-crypt/heimdal. So you must first uninstall app-crypt/mit-krb5, if installed. Then install app-crypt/heimdal and rebuild any packages that were using the previous kerberos implementation.
# emerge --unmerge --ask app-crypt/mit-krb5 # emerge --ask app-crypt/heimdal # revdep-rebuild -- -ask
To enable automatic zone management, net-dns/bind and net-dns/bind-tools should be emerged with the USE flags for berkdb, dlz and gssapi set. To enable them permanently, add the following to /etc/package.use:
net-dns/bind berkdb dlz gssapi net-dns/bind-tools gssapi
Then, emerge net-dns/bind:
# emerge --ask net-dns/bind net-dns/bind-tools
Samba-supplied Libraries (tdb/ldb/tevent)
There are a few Samba libraries that need to be installed. Note that these packages might be keyworded as unstable, so you might need to add the following to your /etc/package.keywords:
~sys-libs/tevent-0.9.17 ~sys-libs/tdb-1.2.10 ~sys-libs/ldb-1.1.12 ~sys-libs/talloc-2.0.7
Additionally, Samba requires sys-libs/tdb and sys-libs/talloc to be emerged with the USE flag python set. To enable this permanently, add the following to /etc/package.use:
sys-libs/tdb python sys-libs/talloc python
Note: In new(er) installations of Gentoo, the above files will be located in /etc/portage/, i.e. /etc/portage/package.keywords and /etc/portage/package.use. They may be symlinked to /etc for backward compatibility.
Now, emerge the packages:
# emerge --ask '=sys-libs/talloc-2.0.7' '=sys-libs/tdb-1.2.10' '=sys-libs/tevent-0.9.17' '=sys-libs/ldb-1.1.12'
Note that ebuilds for the required versions of the above packages might not be availiable in the portage tree. In this case, check Gentoo's Bugzilla for updated ebuilds.
Other Misc. Build/Run Dependencies
To ensure a successful Samba 4 installation, there are a few other packages that should be installed, as shown below:
# emerge --ask net-libs/gnutls sys-apps/acl dev-libs/cyrus-sasl dev-python/subunit dev-python/dnspython net-dns/libidn
FIXME: Are dev-python/dnspython net-dns/libidn still required?
