I've been trying to build myself a current version of the SDK.
So far I've exported the head revision from SVN, opened Bash (using Cygwin) and tried running the bootstrap script.
According to my understanding it should generate a 'configure' script that I just run and then I can 'make' the libraries. However the 'bootstrap' just returns an error:
FIND: Parameterformat falsch
Which is German for 'wrong parameter format'. The resulting 'configure' script is (of course) 0 bytes long.
That's it.
There's a find.exe in the Windows System32 directory. I didn't realise that Bash is using the standard path environment to look for tools, since 'find' is kind of an internal command of the shell. That's where I was obviously wrong. :)
