Also, what about a comparison with latest EFL and not just 1.7? Anyhow, the major problem is that: "pacman -Ss libyuv" returns nothing. That is, it's not even packaged by arch... If anything, we should make it an internal dependency, and not an external one. Dependency hell is an important factor too. -- Tom. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
