Three weeks struggling with the compilation of Qt5.1.1, I finally managed to have one built without failure message during compilation.
The main reason for previous failures, in my own opinion, is mainly due to my ignorance of one crusial factor during shadow build.
You should have your source and build folders in the same level, best in same folder.
This information has been mentioned in an old document about Qt shadow build instructions posted in nokia site before but seems cannot find it now. The current documents/wiki on qt-project site do not mention this explicitly but the example has such implied.
