Minimal dbus version?

[djc]

I was trying to compile Servo in a CentOS 6.5 environment, which has dbus-1.2.24-7. Linking fails:

What versions of dbus are supported? Would it be viable to support this version of dbus?

Oh, so my library made it into Servo, cool :-)

What versions of dbus are supported?

No idea, really, since D-Bus only has online documentation for its latest version, I have no idea when various functions were added. Sorry.

Would it be viable to support this version of dbus?

If those are the only functions I need to remove, then I guess I could add some feature that opts out of them? With the drawback that validation will always succeed and potentially things would panic at a later point rather than return a proper error. Would that be a reasonable solution?

[djc]

I really don't know if that would be a reasonable solution. For the thing I'm trying to build with Servo, I probably don't need dbus anyway, so maybe they should grow a feature to allow for disabling this part.

[diwic]

According to DBus's NEWS file, these functions were added in 1.5.12, which makes 1.6.0 the first supported release.

@djc You might be interested in that the latest version of dbus now has a "no-strings-validation" feature that should enable you to use it on older dbus library version (although I don't know how far back).
