Building MiniGUI 5.0

This repo contains some scripts to fetch and build MiniGUI 5.0.x

This instruction assumes that you are using Ubuntu Linux 18.04/20.04 LTS.

Current Status

Currently, the latest official release of MiniGUI is version 5.0.9.

Main enhancements of MiniGUI Core and its components are as follow:

  • Code tuned for GCC 9.3, so that you can build MiniGUI on Ubuntu 20.04 or other Linux distributions which use GCC 9 or later.
  • MiniGUI Core:
    • Support for compositing schema under MiniGUI-Processes runtime mode. This feature brings the exciting visual effects which are popular on modern desktop computers or smart phones to MiniGUI.
    • New main window types/levels. You now can easily create main windows in different z-order levels. This enhancement allows us to create a special app which acts as screen lock, docker, or launcher.
    • Virtual Window. You now can easily create message threads under all runtime modes to exploit the messaging mechanism of MiniGUI in non GUI threads - we call them message threads.
    • Enhanced timer support. MiniGUI now manages the timers per message thread. Under MiniGUI-Threads runtime mode, you can set up 32 (64 on 64-bit architecture) timers for each GUI threads. If you enabled virtual window, you can also do this for each message thread.
    • Support for listening a file descriptor as long as the underlying system has the select() system call for all runtime modes. Now you can call RegisterListenFD() to register a file descriptor to be listened, and handle MSG_FDEVENT in your window callback procedure to read/write from/to the file descriptor. Before this version, this feature only available for MiniGUI-Processes runtime mode.
    • Support for local data of windows. You can now set or retrieve a local data which is bound with a string name for a window. This will give you an eays-to-use interface to manage various data of a window.
    • Support for hardware cursors under compositing schema. MiniGUI now can utilize the hardware cursors if your graphics device support it. You can also load a cursor from a PNG file.
    • Support for loading icon from a bitmap file. You can now load an icon from a bitmap file such as a PNG file.
    • Unified the message hook functions for all runtime modes. MiniGUI now provides the consistent message hook functions for all runtime modes.
    • Use the update regions for cumulative updating the screen. This will emilinate the flickers due to the frequently redrawning of controls.
    • Cleaned up a lot of internal symbols (the external functions and global variables) in order to avoid name polution.
    • Refactored the code for the following modules: z-order management, message queue, event/message handling, and part of graphics abstract layer.
    • Enhance the NEWGAL engine fbcon (the legacy Linux frame buffer) to support compositing schema.
    • Use upstream harfbuzz instead of the modified harfbuzz.
    • Support for WebP image files.
    • Some new APIs.
  • mGEff, mGUtils, mGPlus, and mGNCS
    • Tune code for MiniGUI 5.0.0 or later.
    • Cleanup code for bad symbols.
  • mGNCS4Touch
    • Tune code to comply with MiniGUI 5.0.0 and mGEff 1.5.0.
    • Tune the speed meter.
    • Enhance ScrollViewPiece and HScrollViewPiece.
  • mg-tests:
    • Add a new test program for various image files in images/ directory.
    • Add new test programs for MiniGUI 5.0.0 in 5.0/ directory.
    • Add new test programs for compositing schema in compositor/ directory.
  • gvfb:
    • Enhanced to use double buffering to support SyncUpdate method.
    • Enhanced to simulate the hardware cursors.

For more information, please refer to the release notes:

Known issues

The following known issues all about hardware cursor of DRM engine:

  • drmSetCursor2 and drmMoveCursor do not work correctly in DRM engine. Libdrm does not provide an interface to set the correct cursor plane, and it seems that X held the cursor plane.
  • When using a AR24 plane for cursor, drmSetPlane seems having a bad performance.

Upcoming features

We plan to develop the following features in the subsequent releases:

  • MiniGUI 5.0.x:
    • A comprehensive demonstration program for compositing schema and a sample compositor with animations.
    • Clean code of other frequently-used GAL/IAL engines.
  • MiniGUI 5.2.x:
    • Support for the WS_MAXIMIZE and WS_MINIMIZE styles.
    • Tune the input method framework for MiniGUI-Processes runtime mode, so that the input method engine can run as a seperate process.

Building MiniGUI

Prerequisites

You should run apt install <package_name> to install the following packages on your Ubuntu Linux.

  • Building tools:
    • git
    • gcc/g++
    • binutils
    • autoconf/automake
    • libtool
    • make
    • cmake
    • pkg-config
  • Dependent libraries:
    • libgtk2.0-dev
    • libjpeg-dev
    • libpng-dev (libpng12-dev on Ubuntu Linux 16.04 instead)
    • libfreetype6-dev
    • libinput-dev
    • libdrm-dev
    • libsqlite3-dev
    • libxml2-dev
    • libssl1.0-dev

You can run the following commands to install all above software packages on Ubuntu 18.04/20.04:

$ sudo apt install git g++ binutils autoconf automake libtool make cmake pkg-config
$ sudo apt install libgtk2.0-dev
$ sudo apt install libjpeg-dev libpng-dev libfreetype6-dev libharfbuzz-dev
$ sudo apt install libinput-dev libdrm-dev libsqlite3-dev libxml2-dev libssl1.0-dev

Note that the libgtk2.0-dev packages is used by the virtual frame buffer program gvfb.

Building steps

Please make sure that you can visit GitHub and you can do sudo on your Linux box.

  1. Clone this repo from GitHub:
$ git clone https://github.com/VincentWei/build-minigui-5.0.git
$ cd build-minigui-5.0/
  1. Copy config.sh to myconfig.sh and edit myconfig.sh to match your needs:
$ cp config.sh myconfig.sh

Note that we found the mirrors from our GibLab repositories to GitHub were often broken due to the well known fire wall. So you can change your myconfig.sh file to use our GibLat site directly:

# Use this if you want to use our GitLab site via HTTPS
REPO_URL=https://gitlab.fmsoft.cn/VincentWei
  1. Run fetch-all.sh to fetch all source from GitHub:
$ ./fetch-all.sh
  1. Run build-deps.sh to build and install gvfb, chipmunk:
$ ./build-deps.sh
  1. Run build-minigui.sh to build MiniGUI 5.0:
$ ./build-minigui.sh
  1. Run mguxdemo:
$ cd cell-phone-ux-demo/
$ ./mginit

When there were some updates in the remote repos, you can run update-all.sh to update them. You can run clean-all.sh to uninstall and clean them.

Note that you might need to run ldconfig to refresh the shared libraries cache before running mguxdemo or other MiniGUI applications.

Options for build-minigui.sh script

You can pass some options to build-minigui.sh script to specify the compile-time configuration options of MiniGUI Core.

If you did not specify the options, it will use the following default options:

procs compositing virtualwindow

The options above have the following meanings:

  • procs: build MiniGUI runs under MiniGUI-Processes runtime mode.
  • compositing: build MiniGUI to use compositing schema.
  • virtualwindow: enable virtual window.

The script uses a simple method for the traditional autoconf options:

  • The first option always specifies the runtime mode of MiniGUI, you should choose one from procs, ths, or sa, which represent MiniGUI-Processes, MiniGUI-Threads, and MiniGUI-Standalone runtime modes respectively.
  • If you specify an option with a prefix -, the feature will be disabled; otherwise it is enabled.

For example, if you want to build MiniGUI as standalone runtime mode and without support for cursor, you can use the following command:

$ ./build-minigui.sh sa -cursor

Notes for demos

For the sample of compositing schema, please refer to mg-tests:

$ cd mg-tests/compositing/
$ ./mginit trackbar

Welcome to MiniGUI 5.0

or

$ cd mg-tests/compositing/
$ ./mginit auto

Dynamic Wallpaper

You can also run other samples, demos, or test programs in mg-samples, mg-demos or mg-tests.

Note that if you configured MiniGUI as a runtime mode other than MiniGUI-Processes, please use the following commands to run mguxdemo

$ cd cell-phone-ux-demo/
$ ./mguxdemo

Commands to build dependencies

The following steps are those ones in build-deps.sh. We list them here just for your information:

  1. Make and install gvfb:
$ cd gvfb
$ cmake .
$ make; sudo make install
$ cd ..
  1. Make and install chipmunk library (DO NOT use the chipmunk-dev package which is provided by Ubuntu):
$ cd 3rd-party/chipmunk
$ cmake .
$ make; sudo make install
$ cd ../..

Cross Building

MiniGUI 5.0.x can run on lots of CPUs with different architectures, such as ARM, MIPS and so on, after cross compiled. There is a directory named cross-build/, in which there are some scripts for cross building.

As an example, there is a directory name arm-r16-linux, which means: This directory is for ARM-based SoC r16, and the operating system is Linux. In this directory, there are two scripts for download packages, and build MiniGUI 5.0.x for ARM version. You can read the README.md in this directory in detail:

Of course you can build your own directory for your CPU and OS.

Change Log

Currently, this repo just includes some scripts to build MiniGUI 5.0.x core, components, and demonstration apps.
