Some -lgudev-1.0 or GAMEPAD_LIBS seems to be missing

[Alberto Garcia]

It seems to work fine in my environment, what version of gudev do you have?

[Alberto Garcia]

Ah, I see, this is fixed in trunk (bug 114901) but fails in the stable branch.

Carlos, we need to add this to Programs_WebKitPluginProcess_LDADD:

I'll update the wiki.

I'm confused, bug 114901 landed in r149169 that is previous to the branch point r154665 and Programs_WebKitPluginProcess_LDADD already have GAMEPAD_LIBS in 2.2 branch

Ah, ok, this only applied to the 2.0 branch, not the 2.2 one.
