I spent a lot of time with ritual dances and launching rays of hate to Apple for their licences and finally I got FreePascal for iPhoneSim and real iOS, and also headers, which were converted from original h-files. And here the first happiness - Hello World(taken from here) with configured Makefile for automatic building and uploading binaries to iPhoneSimulator. So, I'm going to learn Cocoa API and EAGLContext for initializing OpenGL ES context For now there is only compilable core of ZenGL.
