Default HOWTO: Always install an up-to-date port

I know I should, but I very rarely have the latest ports tree on my system and it's for that reason I always make sure that a port I'm about to install is up to date.

So, this isn't a very lengthy or complex howto but next time your about to install a port and are unsure weather it's the latest skeleton version or not run this command first;

Code:
cvsup -i ports/CATAGORY/YOUR-PORT -g /location/of/your/ports-supfile
for example, if i wanted to install libtorrent-devel and my ports sup file was in the root DIR I'd run the following command

Code:
cvsup -i ports/net-p2p/libtorrent-devel -g /root/ports-supfile && cd /usr/ports/net-p2p/libtorrent-devel && make install clean
That's it! But remember it's still important to keep your ports tree up to date as some ports may install other dependencies which you had not accounted for.

If you haven't edited your ports-supfile yet you must do so beforehand, a typical user will only need to edit the *default host= variable and to help you find the fastest cvsup host a tool called fastest-cvsup has been developed, you can find it here;

Code:
/usr/ports/sysutils/fastest_cvsup
An example supfile can be found here;

Code:
/usr/share/examples/cvsup/ports-supfile

It should be pointed out that this is FreeBSD specific.

OpenBSD, notably, requires kernel, userland, and ports to remain in sync, per FAQ 15.4.1.

Very nice howto mate, about dependencies you mentioned you can parse a port Makefile to get dependencies and also update them before building the port:

for example /usr/ports/www/lighttpd/Makefile
Code:
LIB_DEPENDS=    pcre.0:${PORTSDIR}/devel/pcre
LIB_DEPENDS+=           fam:${PORTSDIR}/devel/fam
LIB_DEPENDS+=           gdbm:${PORTSDIR}/databases/gdbm
BUILD_DEPENDS+=         valgrind:${PORTSDIR}/devel/valgrind
RUN_DEPENDS+=           valgrind:${PORTSDIR}/devel/valgrind
                        sqlite3.8:${PORTSDIR}/databases/sqlite3
A simple script will do the job, the only "problem" may be parsing the multiline *_DEPENDS lines.

% make depends-list
Recursive and pretty formatting

This is a nice tip, I always use(d) "cvs co" if I only need to update a single port, this is much easier.

I think I need more sleep if I forgot about such basics, thanks mate.

Thanks for the nice post, I usually don't update my ports tree until I have to build something (or every few months).

Writing a script to handle the depends is worth not having to wait on cvsup/csup to finish the *usual way* !!

I don't suppose there is an equivalent for viewing a ports build options (make config) is there?

I remember working on a program that needed me to dig up a target ports Makefile, locate OPTIONS and generate a custom QDialog for setting the ones desired, including handling <ports-db>/portname/options where necessary -- it was not fun dealing with the makefile part!


And actually now that I try using zsh's tab completion with make and the ports I used for field testing that module:

Code:
Terry@dixie$ cd /usr/ports/net/samba3/                                     7:51
Terry@dixie$ make depends-list                                             7:51
make: don't know how to make depends-list. Stop
Terry@dixie$ make show-options                                             7:51
make: don't know how to make show-options. Stop
Terry@dixie$ cd /usr/ports/editors/vim                                     7:51
Terry@dixie$ make depends-list                                             7:51
make: don't know how to make depends-list. Stop
Terry@dixie$ make show-options                                             7:51
===> The following configuration options are available for vim-7.1.282:
     PERL=off (default) "Enable Perl interpreter"
     PYTHON=off (default) "Enable Python interpreter"
     RUBY=off (default) "Enable Ruby interpreter"
     CSCOPE=off (default) "Enable cscope"
     EXUBERANT_CTAGS=off (default) "Use exctags instead of ctags"
     ATHENA=off (default) "Athena GUI"
     GTK2=off (default) "GTK2 GUI"
     GNOME=off (default) "Gnome1 GUI"
     MOTIF=off (default) "Motif GUI"
     XTERM_SAVE=off (default) ""
===> Use 'make config' to modify these settings
Terry@dixie$                                                               7:51

Just peachy :\

Good stuff. Another tip: You can forgo editing the cvsup file if you use the '-h' option to cvsup. Here's a fully automated command:

cvsup -h `fastest_cvsup -qc tld` /usr/share/cvsup/ports-supfile

However, beware: I have stopped using that, because for a while here in australia (I used -c au) there was one cvsup server that was out of date, and, because no one was using it, it was always the fastest! Caveat Downlodeur.

# make showconfig It's all in /usr/ports/Mk/bsd.ports.mk

The show-options target is _ONLY_ for vim, look at the Makefile:
Code:
show-options:
        @${MAKE} -DWITH_OPTIONS showconfig
It's more complicated if the port doesn't use OPTIONS but just knobs, you'll have to grep the various knobs...
