+----[ Sven Esbjerg <esbjerg@xbsd.net> (05.Aug.2004 09:50): | | 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? | | Sven Esbjerg | +----] 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!
