The CheckEnv.py result is all ok for iOS as shown below.
But when I run "./SDK3Build.py -t iOS", I always get first 3 failed and the others not built:
This time, at least got first 2 working! The "ARSAL" one still failed...
I then check the log, and noticed it's hard coded somewhere and tried to find "ARSDKBuildUtils/Utils/m4/ARSDK.m4" (see green highlighted part), but my directory name is "ARSDKBuildUtils-master" (see red highlighted part) when downloaded from github, and I can see the "ARSDK.m4" file in there (see yellow highlighted part!
After renamed the directory name, yes! Finally got the whole thing compiled ok. That is definitely a lot of work and the SDK is really badly documented.....
