gobject-introspection 0.9.12 FTB with Python < 2.5 or >= 3 selected

[gale@…]

With python 3.2 selected as the default python version using python-select:

$ sudo port upgrade atk
--->  Computing dependencies for gobject-introspection
--->  Configuring gobject-introspection
Error: Target org.macports.configure returned: configure failure: shell command failed (see log for details)

And then from the log:

:info:configure checking whether Python support is requested... checking for a Python interpreter with version >= 2.5... python

:info:configure not found
:info:configure configure: error: Python headers not found

This appears to be a problem with an autoconf script. The script in question could easily be fixed to work with all versions of python by adding parens:

import sys; print(sys.prefix)
import sys; print(sys.exec_prefix)

Seems to be the same issue as #28468: gobject-introspection uses "python" when it should use a specific known-good version of python instead.

Replying to ryandesign@…:

Seems to be the same issue as #28468: gobject-introspection uses "python" when it should use a specific known-good version of python instead.

It's two different issues, but yes, that would fix both of them.

Note that this port is a little unusual in that it seems to want to compile its own extension to the python interpreter (since it is trying to verify the availability of the python headers). So it may take a little extra care to make sure that all the needed bits are in place when narrowing the port to a specific python version.

I know that we're usually talking to the wall, but we probably should complain about this again upstream.

ummm .. no, that thing with the parens does not really fix it.

i made the changes to the configuration file by hand

bash-3.2# grep "sys.exec" config*
configure:py_exec_prefix=`$PYTHON -c "import sys; print (sys.exec_prefix)"`
bash-3.2# grep "sys.prefix" config*
configure:py_prefix=`$PYTHON -c "import sys; print (sys.prefix)"`

bash-3.2# python_select -l
Available versions:
current none python24 python25 python26 python26-apple python27 python32
bash-3.2# python_select -s
python32

so .. any other suggestions?

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #32398.

The workaround would be to install and select python27, clean gobject-introspection and try again.

[nhojpatrick (John Patrick)]

Fixed the issue by installing and selecting python 2.7.

Does this mean gobject-introspection will be update to record that it requires a specific version of python as a dependency.
