The README file of the qt4.8.7 source code told the following info: ----------------------------------- INSTALLING Qt If you have a source package (a .tar.gz, or .zip file), follow the instructions in the INSTALL file. On Windows and Mac OS X, if you want to install the precompiled binary packages, simply launch the package and follow the instructions in the installation wizard. For Mac OS X Carbon, the binary package requires Mac OS X 10.4 (Tiger) or later and GCC 4.0.1 to develop applications. Its applications will run on Mac OS X 10.4 and above. For Mac OS X Cocoa, the binary package requires Mac OS X 10.5 (Leopard) or later and GCC 4.0.1 to develop applications. Its applications will run on Mac OS X 10.5 and above. -------------------------------------------- As you can see, it only told the case for installing on Win / Mac OS, and not the case for Linux.
