Hi, all,
I've added that 'extra-libraries' to .cabal, and also modules for fcntl.h
and sys/mman.h (mmap). Would you please test it and check if it solves
the problem before I upload it to hackage?
https://bitbucket.org/mauricio/bindings-dsl/downloads/bindings-posix-1.2.3.t...
Just download from that link, unpack and do 'cabal install' inside the
new directory.
Best,
Maurício

So for guys trying the examples with that error I'd recommend the following commandline:
cabal install v4l2-examples --ghc-option=-lpthread
I think this could be a bug in bindings-posix (maintainer CC'd), I guess it could do with this in its .cabal file:
Extra-libraries: pthread
Can't really play about with the webcam right now but I'd had a small but cool project I've had in mind for a while that v4l is perfectly suited for, so I'll get back to you with my experiences. Thanks for releasing it, Claude. :-)
Cool, look forward to seeing it! Hopefully I'll soon find time to upload to Hackage a preliminary (feature-incomplete) release of the higher-level interface that I'm working on; until then: https://gitorious.org/hsv4l2/v4l2
