+1, I'd most definitely appreciate help with any of my team-maintained
packages as I haven't had time for the past while to do so. If you
could also keep the stable-backports version of 0ad up to date, that
would also be greatly appreciated. Thank you!

Before I start to package 0ad alpha 22 I tried to build the Debian package for version alpha 21. And I have a strange problem building the package 0ad. No problem with the package 0ad-data.

If I use "dpkg-buildpackage -us -uc" then it works fine. So my configuration is not completely broken :-)

But if I use "debuild" (the command I use to build packages) I get an error:

The problem is with the script libraries/source/spidermonkey/mozjs-38.0.0/python/mach/mach/mixin/process.py and the code:

# Perform detection of operating system environment. This is used by command
# execution. We only do this once to save redundancy. Yes, this can fail module
# loading. That is arguably OK.
if 'SHELL' in os.environ:
    _current_shell = os.environ['SHELL']
elif 'MOZILLABUILD' in os.environ:
    _current_shell = os.environ['MOZILLABUILD'] + '/msys/bin/sh.exe'
elif 'COMSPEC' in os.environ:
    _current_shell = os.environ['COMSPEC']
else:
    raise Exception('Could not detect environment shell!')

In my case SHELL is defined as:

$ echo $SHELL
/bin/bash

I searched the Internet and found other people having the same problem when building Firefox. The solution was to define SHELL. But SHELL is already defined in my case.

I have no idea why "debuild" would remove the SHELL definition.

It is a know problem?

Vincent, do you use "debuild" to build the 0ad package?

Thanks
