Linux compilation

Requirements

• g++ compiler with good C++14 support, GCC 5 and above
  • install g++ package for Debian-based system (xUbuntu, Linux Mint, etc.)
  • install gcc-c++ package for rpm system (Fedora, OpenSUSE, etc.)
• libGL development files (required by any Qt application)
  • install libgl1-mesa-dev package for Debian-based system (xUbuntu, Linux Mint, etc.)
  • install mesa-libGL-devel package for rpm system (Fedora, OpenSUSE, etc.)
• Qt 5, at least 5.9, 5.12 is recommended

Installing Qt

You can skip this section if you know how to do it.

Qt instalation is pretty simple, don't worry if you know nothing about Qt and do its instalation first time.

Download Qt installer, run it and follow its instructions. Root is not required to install Qt.
You can safely uncheck everything execpt Desktop gcc.

Getting sources

There are 2 ways to get sources:
1. download archive from release files (stable code)
2. download snapshot/clone repository (latest code)

Also you will need in resources (skins, textures, etc.)

Compilation

• extract all downloaded archives
• move resources to one folder
• open scripts/create_package.sh from sources folder in any text editor and change QT_ROOT, CLOCK_SRC_PATH, CLOCK_DATA_PATH variables corresponding to your system
• open terminal and navigate to clock sources root (CLOCK_SRC_PATH value)
• run build script: ./scripts/create_package.sh

Compilation will take about few minutes (depending on hardware), and as result you will get Digital Clock folder and digital_clock_4-linux.tar.xz alongside with sources folder. Digital Clock folder will contain ready to use application, digital_clock_4-linux.tar.xz is compressed version of it.

Notes

• Qt no longer supports 32-bit linux. maximum Qt version for 32-bit system is 5.5. clock compilation is not possible with it. compile Qt 5.9 or newer from sources manually
• to run clock use digital_clock.sh
• theoretically clock can be compiled for any unix-like platform which is supported by Qt, but it is not tested
• some cool stuff is available only in Linux! see config_desktop.sh --help for details

What about version 5.x for Linux ?
