Hi Qihong,

Under your link: there is a package "qt-everywhere-opensource-src-4.8.6.tar.gz". You can unzip this package by "tar zxvf qt-everywhere-opensource-src-4.8.6.tar.gz". Enter in unzipped folder, you can build Qt by "./configure", "make", and "make install". By default, it will install Qt to /usr/local. If you prefer other location, please parse "--prefix=/your_preferred_install_location" to the command "configure".

After you successfully build Qt, type "qmake --version" to test Qt version.

Hope this helps.

Thanks,
Yang

Hi Yang,

I managed to compile the current git source on Ubuntu 18.04 using cmake after some fixes to the CMakeLists.txt files. Would you be interested to apply these changes to the main branch?

Cheers,
Satya
