Answer 1

I can reproduce this problem if I check "Clear system environment" on the Projects' Build Settings page. Try unchecking that box.

Answer 2

I encountered a similar problem. My TMP variable has Chinese characters, which makes qt creator produce error: cannot open ** for write.

Try to change your TMP variable with only English characters, no spaces. Ensure that the folder exists and you have permissions to access it.

My Qt version: Qt 5.4.0 for Windows 32-bit (VS 2013, OpenGL). You can set this in Qt Creator
