According to this page, they are now on version 3.6, the first run was quite interesting, as "CheckEnv.py" picked up the folder name was incorrect straight away. This is certainly a huge improvement, as last time it took me a while reading through lots of logs to work that out.
After that's fixed, tried to run "./SDK3Build.py -t iOS", then it goes downhill unfortunately. It died 1st time after "openssl", and took 11m 4s.
2nd time it died with "ARSAL" and only took 1m 22s.
The error was as shown below "no known instance method for selector", which I have absolutely no idea what does that mean.
After that I can't move forward any more, tried a few times all failed, also tried with "SDK3Build.py -t iOS --force-clean" still same result. Very frustrating...
Searched the net and found this post on parrot forum also experiencing similar issue just a few days ago. Let's hope it can be resolved pretty soon.
So my conclusion is, again, a very bad experience with ARDrone SDK... And don't forget this is just to compile the SDK framework to be included in the XCode, you still have to write your objective C/Swift code and build into an iOS app..... what a pain, why can't parrot just release a compiled framework, how hard can that be?
