qgis cannot be installed without specifying variants

[athundt@…]

qgis fails to install as follows, with python 2.6.1 already installed via macports:

$ sudo port install qgis
--->  Computing dependencies for qgis
--->  Extracting qgis
Error: Qgis requires python.
Error: Target org.macports.extract returned:  Please select a python variant.
Log for qgis is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_gis_qgis/main.log

$python --version
Python 2.6.1

Macports python26 is at version 2.6.6. You should try running the following:

sudo port install python_select
sudo python_select python26

I cannot reproduce your error. What is in your /opt/local/etc/macports/variants.conf file?

[athundt@…]

Here is the output of the two items you requested. I apologize for not mentioning that I had already tried python_select. Also, variants.conf appears blank.

~:sudo python_select python26

# To specify global variants to use for all port builds,
# customize this file to list variant settings you want.
#
# Any variants specified here that are not supported by
# a port will just be ignored. Multiple variants can be
# specified per line, or one per line is also allowed.

# Example:
# +ipv6 +no_x11

It wants you to specify which version of python to use by selecting one of its variants. See port variants qgis. I guess you want it to choose for you if you don't specify?

BTW, the python30 variant doesn't work and should be removed.

[athundt@…]

Yes, i believe qgis should automatically default to the variant using the result of python --version.

I will try to implement the necessary modifications. I am off for Easter vacations with no Mac at hand, but I'll try to cope nevertheless. I'll keep you posted.

[macsforever2000@…]

I see why it worked for me. I have +python26 in my variants.conf file and doing a "port info qgis" shows (+)python26 as a default, but that comes from my variants.conf. I thought it was a default for the port.

Sorry for being late on this. I have to rebuild quite a lot of dependencies (e.g. Qt4) and it takes quite a lot of time since I don't have a last-generation machine. I'm working on it though.

[athundt@…]

Don't worry, no need rush for me personally. I've managed to get qgis working by specifying the python version by hand. The automation is just a convenience for both myself and other users. Thanks for the help!

Replying to athundt@…:

Yes, i believe qgis should automatically default to the variant using the result of python --version.

No, ports should not do this.

But I agree qgis should have some default version of python. And this was done in r87346.
