Confusing error when 'diff' is missing

[kripken]

bzr diff --diff-options -w (or with =-w, "-w", ="-w") works fine on Ubuntu (producing a diff that ignores whitespace), but on Windows I get

=== modified file 'src/SConscript'
bzr: ERROR [Error 2] The system cannot find the file specified

This is happening because "--diff-options" causes bzr to use the external diff tool, which can not be found.

Bazaar should print a more sensible error if it can not find diff.exe.

I wonder if we're outputting a path like
c:\\foo\\bar/src/Sconscript

I would actually guess that we can't find 'diff.exe', it isn't a program that we bundle with the installer.

You could try doing "bzr diff --diff-option -w -Derror" and we can check the traceback.

I'm pretty sure you need to install diff separately (as you do on Ubuntu, but it is almost always there)
http://gnuwin32.sourceforge.net/packages/patch.htm

is one possibility, I think there are others.

John was right, installing the GNU diff tool manually fixes this issue.

(Sorry for the late response.)
