Bug Description

Binary package hint: scons

When I try to build Widelands (widelands.org) from source, it does not work with Python 2.6, I get the following error:

Checking for a working C++ compiler ... no
Can't even compile the simplest C++ program! Your setup is beyond broken. Repair it, then try again.

Looking at build/config.log shows me:

g++ -o build/sconf_temp/conftest_0.o -c - D N O P A R A C H U T E - D D E B U G -Ibuild/native-debug build/sconf_temp/conftest_0.cc
g++: D: No such file or directory
g++: N: No such file or directory
g++: O: No such file or directory
g++: P: No such file or directory
etc.

Changing the symlink /usr/bin/python to python2.5 solves the problem.
It looks like there have been bug reports about scons failing with python2.6 before and that this should be fixed by now, but in this case it isn't.

have you done something like

env['CPPDEFINES'] += "-DNOPARACHUTE"

when you should have written

env['CPPDEFINES'] += ["-DNOPARACHUTE"]

perhaps?

Well, I have not written any of this source code... *g

There are indeed lines like
'build/scons-tools/scons_configure.py: env.Append(CCFLAGS='-DNOPARACHUTE')'

So if this different behaviour in python 2.6 compared to 2.5 is intended, this is a problem of the widelands source and I could file a bug report there.?

Okay, this issue is somehow fixed. The widelands devs changed something in their scons handling and now compiling works with Python 2.6, as well. Closing.

While this isn't an issue with scons, it is still present in the version of widelands in Karmic, resulting in it to FTBFS.

This bug was fixed in the package widelands - 1:13-2ubuntu1

---------------
widelands (1:13-2ubuntu1) karmic; urgency=low

  * debian/rules:
   - Add localedir and build_id flags.
   - Call scons directly inorder to use the system version not
     the bundled copy.
  * debian/patches/python2.6transition.dpatch:
   - Patch env.Append() lines in build/scons_configure.py to
     work with python 2.6 (LP: #348896).
  * debian/control: Build-Depend on scons.
