Ports with several versions

[hanzer]

I would like to build Python-3.4 (on 5.6-stable i386).

$ cd /usr/ports/lang/python
$ ls returns:

2.7/             3.3/             3.4/             CVS/             Makefile         Makefile.inc     python.port.mk

$ make show=FLAVORS returns:

===> lang/python/2.7
 
===> lang/python/3.3
 
===> lang/python/3.4

and $ ls /usr/ports/lang/python/3.4/pkg/ returns:

CVS/           DESCR-gdbm     DESCR-idle     DESCR-main     DESCR-tests    DESCR-tkinter  PLIST-gdbm     PLIST-idle     PLIST-main     PLIST-tests    PLIST-tkinter

So I guess the SUBPACKAGEs are "-gdbm -idle -main -tests -tkinter".

How do I build all of the subpackages (assuming none of them conflict with another) of the 3.4 version?

# env FLAVOR="lang/python/3.4" make and
# env FLAVOR="3.4" make both return:

Fatal: can't flavor a SUBDIR (in lang/python)
*** Error 1 in /usr/ports/lang/python (/usr/ports/infrastructure/mk/bsd.port.subdir.mk:187 '.BEGIN': @exit 1)

They're going to be built. If you want to install everything pass:

# make install-all

Thanks.

The part that I am really stuck on is how to select the major version - 2.7, 3.3, and 3.4 are available. It's tempting to just change directory to /usr/ports/lang/python/3.4 and try # make install-all but it's not clear [to me] if that is the correct way to do it.

[ibara]

Yes.

I looked through the make files and it seems like SUBDIR might be used in cases like this in a similar way as FLAVOR or SUBPACKAGE is used. I haven't found any documentation to support that notion but I am trying:

# cd /usr/ports/lang/python
# make SUBDIR="3.4" COPTS="-march=native" CXXOPTS="-march=native" build 2>&1 | /usr/ports/infrastructure/bin/portslogger /tmp/ports_log

I am way off?

update: The SUBDIR method didn't work. Changing directory to 3.4 then building does work.

For future readers...
The way to work with the ports tree if you only want to build a single port is to go into a leaf directory and issue commands.
