User:Sgonzalez/Samba 4 OS requirements/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 greater) The following set of commands will install and set up python-2 as the default python interpreter.
# emerge --ask '<dev-lang/python-3' # eselect python list # Note the index number of the python-2 installation # eselect python set <# of python 2 from previous command> # 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 developers recommend using heimdal. So we must first uninstall mit-krb5 (if installed,) install heimdal and rebuild any packages that were using the old kerberos implementation.
# emerge --unmerge --ask app-crypt/mit-krb5 # emerge --ask app-crypt/heimdal # revdep-rebuild -- -ask
To enable automatic zone management with bind, bind (and 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 bind:
# emerge --ask net-dns/bind net-dns/bind-tools
Note that if you have problems with samba's gssapi updates to bind, try using the alternate kerberos implementation of app-crypt/mit-krb5.
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 dev-libs/cyrus-sasl net-libs/gnutls dev-python/dnspython net-dns/libidn dev-python/subunit
Samba-supplied Libraries (tdb/ldb/tevent)
Please use this as a reference point only, anywhere there is an = after and emerge command, it is installing a specific version, this can cause issues with newer samba releases.
# USE="dlz python gssapi" emerge cyrus-sasl heimdal bind bind-tools gnutls dnspython gdb libidn subunit # ACCEPT_KEYWORDS="~amd64" USE="python" emerge =sys-libs/tdb-1.2.10 =sys-libs/tevent-0.9.15 =sys-libs/ldb-1.1.12
Obviously that would be ~x86 instead of ~amd64 on a x86 arch, also don't forget to
# eselect python set 1
where 1 is python 2.X (3.X is not yet supported) if you don't know which version you are using, eselect python list will give you a list of available ones.
