YLmf OS Compilation System

I. What is YBS?

YBS refers to the packaging system of Ylmf OS (Ylmf OS Build System). It is a ports-like system used to compile software from source code. In Ylmf OS, yget is specifically for managing binary software packages, while YBS is specifically responsible for compiling source code and packaging it into installable ypk packages. Ports is a system used by FreeBSD that performs a series of operations such as downloading, decompressing, patching, compiling, and installing source code packages. A port contains some files to guide the download, compilation, and installation of the source code, and the system automatically completes the operations.

YBS is composed of a directory tree located at /var/ybs/pbslib, which contains many subdirectories, each belonging to a certain category and named after the corresponding package that can be created. This directory does not contain packages or source code, but rather contains a pbs file and a files directory. The Package Build Script (referred to as pbs) is a script - a text file (containing instructions for the compilation and packaging process, including the download address of the source code package, etc.), and the files directory stores additional files, such as patch files, etc. The most important part of YBS is the pbs file.

1. Obtain the YBS tree
Run as root

01. #ybs --sync
The code can synchronize the YBS tree from the server, managed by git. With the YBS tree, users can customize and compile and package software from source code.

YBS contains a complete toolbox of the following structures and tools:
YBS directory tree: /var/ybs/pbslib, containing pbs files and related files of all software
ybs command: reads the pbs file, compiles the source code, and creates a ypk package.
pbs file: records instructions for creating the package and the source code address.

2. What YBS is used for:

Compile software not in the official source of Ylmf OS from source code. Of course, you first need to write a pbs file.
Customize existing packages to meet your specific needs, modify the existing pbs file, usually to enable or disable relevant configuration options
Rebuild the entire system with other compiler flags.
Cleanly compile and install your own customized kernel, just modify the pbs file of the kernel.
Of course, you can also install software in the traditional way configure/make/make install, but ybs can automate this work.


3. Global compilation environment /etc/ybs.conf specifies environment variables and compiler flags.

01. $ cat /etc/ybs.conf

02. CC=gcc

03. CXX=g++

04. #CFLAGS="-march=native -mtune=native -O2 -fomit-frame-pointer -pipe"

05. CFLAGS="-march=i686 -mtune=i686 -O2 -pipe" #

06. CXXFLAGS="$CFLAGS"

07. MAKEOPTS="-j6" # Number of make processes

II. Introduction to the pbs file:

1. The location and naming rules of the pbs file are fixed.
Take leafpad as an example, run:

01. # ybs -w leafpad

02. /var/ybs/pbslib/app-editors/leafpad/leafpad_0.8.18.1.pbs
app-editors Software category
leafpad Software name
leafpad_0.8.18.1.pbs Software name_Main version number.pbs
leafpad_0.8.18.1-ylmf1.pbs Software name_Main version number-Corrected version number.pbs

2. Simple pbs file:
Take leafpad as an example, run:

01. $ cat /var/ybs/pbslib/app-editors/leafpad/leafpad_0.8.18.1.pbs

02. #

Run:

01. #ybs -s leafpad
You can query

Run:

01. #ybs -i leafpad
Start compiling and packaging leafpad

2. ybs can automate the compilation and packaging work, mainly because of the compilation rules of the pbs file. Let's learn more complex pbs files. /var/ybs/pbslib/template.pbs is a template with detailed rules.

01. $ cat /var/ybs/pbslib/template.pbs

III. Introduction to common ybs commands:

Search:

01. $ ybs -s leafpad

02. * Searching for leafpad ...

03. leafpad

04. Installed: 0.8.18.1 2011-06-02,09:43:36

05. Available: 0.8.17 | 0.8.18.1

06. Homepage: http://tarot.freeshell.org/leafpad/

07. Description: GTK+ based simple text
means installed
s means stable branch
t means test branch

Locate the pbs file and find the available pbs file of the highest version

01. $ ybs -w leafpad

02. /var/ybs/pbslib/app-editors/leafpad/leafpad_0.8.18.1.pbs
Compile a certain package, and automatically compile dependent packages. Add the -p parameter to simulate execution:

01. # ybs -i -p leafpad

02. * Calculating dependencies...

03. sys-libs/zlib_1.2.5

04. dev-util/pkgconfig_0.23

05. app-admin/gamin_0.1.10

06. dev-libs/mpfr_2.4.2

07. dev-libs/gmp_4.3.2

08. x11-libs/xcb-util_0.3.6

09. x11-libs/gtk+_2.20.1

10. app-editors/leafpad_0.8.18.1
means installed, and no upgrade or downgrade is required
means this package needs to be downgraded
means this package needs to be upgraded

The installed package is compiled forcefully, and the -F parameter is added. If the -p parameter is not added, leafpad will start to be compiled:

01. # ybs -i -F -p leafpad

02. * Calculating dependencies...

03. dev-util/pkgconfig_0.23

04. app-admin/gamin_0.1.10

05. sys-apps/linux-headers_2.6.37 ----> sys-apps/linux-headers_2.6.38.2

06. dev-libs/mpfr_2.4.2

07. dev-libs/gmp_4.3.2

08. x11-libs/xcb-util_0.3.6

09. x11-libs/gtk+_2.20.1

10. app-editors/leafpad_0.8.18.1
means installed, but still compiled forcefully

Compile a single software package without automatically compiling dependencies. This method is under the premise that the dependencies are known to be fully satisfied. If the -p parameter is not added, leafpad will start to be compiled immediately without calculating dependencies.

01. # ybs -is -p leafpad

02. * Installing leafpad ...

03. app-editors/leafpad_0.8.18.1
For more options, please refer to ybs --help

IV.
The Ylmf OS system and the software running on it are composed of countless software packages. The compilation rules of each software package are controlled by the pbs file. It can be said that pbs is the soul of Ylmf OS. And the ybs method realizes automation to a certain extent, and at the same time, through the pbs file, complete transparency and control over the compilation and installation process are also maintained.

In addition to sharing ypk packages, everyone is welcome to submit ybs files to us. At the same time, friends with the ability are welcome to join the development team. We will give you an account to maintain the ybs tree together with the developers. Please contact ylmfos@115.com.

Xiong Puxiang
Founder of RT-Thread Real-Time Embedded Operating System
21 people agreed with this answer
It seems some people asked, let me generally talk about possible ways.

First of all, what is your purpose of learning? It's best to have practice if you learn. Just learning without final practice will be forgotten soon. So the overall steps are: learn, practice; encounter problems in practice, then go back to study some details; repeat like this, and finally can master/expertly understand the whole system.

Let's get down to business and talk about how to effectively learn RT-Thread.

0. Please prepare basic C language knowledge; know how to write basic C language code; when there are compilation errors in written code, know how to correct them;

1. Find a set of development boards to start with; because considering the reason of code debugging, it is recommended to choose development boards with stm32 or nxp lpc series processors. Spend some time, basically without much code modification, get the kernel + shell running. <This is also the process of familiarizing with the development environment and creating projects (you can also understand how to generate project files for Keil MDK/IAR and other tools using the command line)>

2. Being able to get the basic kernel + shell running has actually entered the threshold of RT-Thread. Adding a small code, printing "Hello RT-thread\n" should be no problem. On this basis, the next step is the scope of real-time operating system learning. Classic (real-time) operating system problems can be two: producer-consumer problem; philosopher problem. You can find the corresponding problem descriptions, and then implement them on the development board (preferably in multiple ways). <By using the mechanisms provided by RT-Thread to solve these problems, you should basically understand how to create multiple tasks in RT-Thread, how to synchronize between multiple tasks, and how tasks communicate with each other.> If there are still some basic knowledge of the operating system that you don't understand during this process, you can find some books to check. In 2017, there should also be a book based on RT-Thread, which can be read in parallel.

3. After solving the producer/consumer and philosopher problems, basically it can be said that you have entered the door of RTOS (this is not just for RT-Thread). Then you can browse and get familiar with and use other parts of RT-Thread, such as timers, memory management, etc. Of course, it is also necessary to understand the device framework of RT-Thread. The simplest: how to use a serial port device, and you can also see how the shell operates the serial port device. Here, that "RT-Thread Programming Guide" is the most important reference, you can read it carefully, and most problems can probably get answers in it. <If you plan to use RT-Thread for a long time, it is necessary to understand the device framework (not necessarily very familiar), because a principle of RT-Thread is to be able to use it as a whole, and they can integrate with each other; when the peripheral components need to involve underlying operations, they are all based on the RT-Thread device model to achieve portability of each chip platform>

4. Understand the components of RT-Thread. The core components of RT-Thread include: real-time kernel; command line shell; file system; TCP/IP network protocol stack, etc. Then, it is the standard interface trying to be compatible with POSIX. According to this principle, for the file system and TCP/IP network protocol stack, RT-Thread (tries) to provide standard interfaces, hoping to achieve quick start and quick migration. So when using these components and not knowing how to use them, it is also very helpful to cross-reference some POSIX materials. By this step, it is actually closely related to practice. Without practice, this part will also be forgotten very quickly.

The steps to learn RT-Thread can basically be followed in a similar way. By step 4, it is entering the long-term process of learning/using. The entry time in the front should not be long, especially with certain guidance, this time should be shorter. In my previous experience, you can make small tasks one by one to carry out, complete them and quickly gain practical experience. I used to write a short "RT-Thread Experiment Manual", but there are only topics, no answers. It is publicly posted on the Internet, and everyone just browses it, lacking the actual hands-on link.
