I have a problem compiling any example. I'm using eclipse and mingw32.exe on Windows 7.

From the log it looks like you are using Cygwin environment (/cygdrive/d/AiThinkerIDE_V0.5/cygwin). ESP-IDF build system does not support Cygwin. Please follow the Getting Started Guide for Windows to install MSYS2 environment.
