| I'm trying to port RTFM (http://bestpractical.com/rtfm/) since we use it at
| work.
|
| It's my first port and I'm unsure of how the following should be done.
| Intalling RTFM is simple. Untar the tarball. Edit the Makefile
| and run make install.
| However the Makefile needs to be changed according to the postgresql
| installation - it needs a username for tampering with the database and a
| password if that is required. It also needs to know where rt lives.
Hej!
Have you started writing a skeleton port Makefile?
| I would like to provide the user with defaults (pgsql user and /usr/local/rt3
| as installation directory) but I would also like the user to be able to
| specify these options.
Use variables WITH_POSTGRESQL_USER and WITH_RT (or whatever
you would like to call them) in your port's Makefile. Once
your port is done, the user would have to call make like so:
make WITH_POSTGRESQL_USER=pgsql WITH_RT=/usr/local/rt3
That should do it.
| I guess my question is: can I run some kind of script just after extracting
| but before installing?
Of course. Just define a post-extract target in your port's
Makefile and write your actions there:
post-extract:
${ECHO} "This will be called after extracting the distfile"
| Is it advisable to create a sed script that does the actual mangling of the
| Makefile or?

Yes, and you can do that from your port's Makefile by
calling ${SED} or ${REINPLACE_CMD}.
If in doubt, check the Porter's Handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook
also, you can take a look at the magic between the scenes by
reading bsd.port.mk (should be in /usr/ports/Mk). It is well
documented and serves as an ideal reference.
And finally, do take a look at other port's Makefiles to see
how they use this things.
Happy porting!
