Preface

Have you heard of it? Linyaps – a new era Linux desktop application distribution and management solution should know that one of the core features of the Linyaps solution is: "Through isolation technology, compatibility conflicts caused by upgrades between systems and applications, and applications and applications are completely solved."
Based on this feature and Introduction to Linyaps technical architecture , we can generally know that the Linyaps solution mainly isolates applications and systems through sandbox and container solutions, which means that most directories in the application container only have read-only permissions and cannot be used as a daily system environment.
coincides with 2024年11月16日下午 held Linyaps open source community’s first university technology salon Medium, 如意玲珑 and OpenTenBase The open source community has carried out "cross-border" sharing, experimentally carried out in Linyaps container OpenTenBase Source code compilation of open source projects. After the event, I continued to compile 如意玲珑 and OpenTenBase Carry out cross-border exploration and discover scenarios with higher playability (practicality)

Linyaps container operation display

To compensate for the inability of some friends to witness 如意玲珑 and OpenTenBase A live demonstration of "cross-border" sharing in the open source community. I will briefly show you the operation process here.

Preparation

This sharing is based on deepin 23 distribution, so you need to prepare a version that can build Linyaps applications before performing any of the following steps. deepin 23 System environment

For specific steps, please refer to:

1. Since we need to connect to the Internet to obtain the runtime library of the Linyaps container and possible third-party libraries during the construction process, we need to ensure a smooth network connection during the entire operation process.
2. Simply write a version of Linyaps build project configuration file according to the following template linglong.yaml , to generate a container that meets the requirements

The main points that need attention are the following:
* Since this operation is to directly enter the container for operation, therefore build Some construction rules do not need to be written in detail.
* Since this involves compilation operations, in order to include the required runtime library to the greatest extent, we added runtime Section, specific writing specification reference Introduction to build configuration files   Basic knowledge of Linyaps application construction engineering

1. Completing preparations linglong.yaml After editing and extracting the relevant source code to the current directory, we can start compiling

Project compilation demonstration

*There is a knowledge point that needs to be inserted here: in the Linyaps container, and building the project configuration file linglong.yaml Sibling build directories will be mapped as /project Table of contents
Everything is ready, we can start compiling

1. In order to facilitate operation, we open two shell windows at the same time in the build directory, respectively for 玲珑容器操作 and 普通操作
2. Enter Linyaps container

szbt@szbt-linyaps23:/media/szbt/Data/ll-build/openTenbase$ ll-builder build --exec bash

When the path changes like the following, it means that we have entered the Linyaps container

szbt@szbt-linyaps23:/project$

1. Passed 普通操作 Window decompress the openTenbase source code into the build directory. I decompress it into a subdirectory separately.

szbt@szbt-linyaps23:/media/szbt/Data/ll-build/openTenbase$ tar -xvf OpenTenBase-v2.6.0-src.tar.zst -C src/

1. After decompressing the source code, we should correctly choose which compilation system/tool to use before compiling any source code. But the thoughtful thing is, OpenTenBase The open source project has prepared introductory documents for compilation and installation for us, we can read it first OpenTenBase source code compilation and installation to prepare compilation materials
2. Since it does not exist in the Linyaps container apt The explanation of installing dependent packages online, so we will skip it first. 依赖安装 Steps. However, it should be noted that the libraries/compilers currently provided by the Linyaps container are: gcc12.3, zlib, openssl3 , other unspecified libraries may not exist in the container and require us to compile manually (remember the key points, we will test them later)

In summary, we may be missing something suggested in the document libreadline-dev libossp-uuid-dev

1. Without further ado, we pass 玲珑容器操作 window to enter the source code directory. In order to avoid interference with the source directory as much as possible, I will create a new one here. build Directory used for compilation. Enter build After the directory we enter OpenTenBase source code compilation and installation in configure Instructions to configure the build project. According to Basic knowledge of Linyaps application construction engineering , we will --prefix bestow $PREFIX value, I finally performed the following operations locally:

../configure --prefix=$PREFIX  --enable-user-switch --with-openssl\
 --with-ossp-uuid CFLAGS=-g\
 LDFLAGS=-L$PREFIX/lib/ CFLAGS=-I$PREFIX/include\
 --with-libs=$PREFIX/lib/ --with-includes=$PREFIX/include\
 CPPFLAGS=-L$PREFIX/include

1. As you can see from the picture, there is an error that prevents the configuration from being completed. We see that libreadline Library cannot be found, considering Basic knowledge of Linyaps application construction engineering For the directory characteristics mentioned in , I checked the corresponding include No resources related to this library could be found in any directory.

configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.

szbt@szbt-linyaps23:/project$ ls /usr/include/ |grep readline
szbt@szbt-linyaps23:/project$ ls /runtime/include/ |grep readline
szbt@szbt-linyaps23:/project$ 

Combined with this error report, it can basically be judged that the library is missing. According to the prompts, we can use --without-readline parameter to disable this library to skip errors

1. After disabling it, we re- configure , appeared uuid The relevant library is missing. Since I cannot completely confirm the missing library, I executed ./configure --help to see what parameters the current project supports, and soon I found and uuid related parameters, and updated to the following parameters:

../configure --prefix=$PREFIX  --enable-user-switch --with-openssl\
 --with-uuid=e2fs CFLAGS=-g\
 LDFLAGS=-L$PREFIX/lib/ CFLAGS=-I$PREFIX/include\
 --with-libs=$PREFIX/lib/ --with-includes=$PREFIX/include\
 CPPFLAGS=-L$PREFIX/include --without-readline

1. After re-executing, the project configuration is successfully completed, and this step is executed directly. make Just operate
2. In this process, there appeared successively bison flex Program missing error, we return 普通操作 The window downloads the corresponding source code to the current build directory and enters 玲珑容器操作 window recompile

1. Recompile OpenTenBase项目 , and readline The relevant error report no longer exists. After recompiling, the first time make It can be completed successfully.
2. Then we immediately started the second time according to the documentation make . But there is a problem that the relative path cannot be found.

make: *** 没有规则可制作目标“../src/Makefile.global”。 停止。

1. Taking a closer look, this is because I used a separate compilation directory when compiling the upper-level source code, destroying the original Makefile settings, so I regenerated the Linyaps container and changed the compilation directory to configure Same level directory, press 1==>11 Compile the sequence completely once
2. But this time make Appeared in readline The header file is missing, which means that even if we disabled this library in the previous step, we still cannot leave this library if we want to complete the compilation of all binary programs.

We refer to 1==>10 Steps to recompile readline and its dependent runtime libraries libncurses After that, the second compilation was successfully completed.

./configure --prefix=$PREFIX  --enable-user-switch --with-openssl\
 --with-uuid=e2fs CFLAGS=-g\
 LDFLAGS=-L$PREFIX/lib/ CFLAGS=-I$PREFIX/include\
 --with-libs=$PREFIX/lib/ --with-includes=$PREFIX/include\
 CPPFLAGS=-L$PREFIX/include --with-readline

Compile result test

in completion make install Finally, since the –prefix was modified to $PREFIX, which is also in the container’s default PATH, I checked to see if I could run this binary normally:

szbt@szbt-linyaps23:/project/src/OpenTenBase-v2.6.0/contrib$ pgxc_ctl --help   
/bin/bash
pgxc_ctl [option ...] [command]
option:
   -c or --configuration conf_file: Specify configruration file.
   -v or --verbose: Specify verbose output.
   -V or --version: Print version and exit.
   -l or --logdir log_directory: specifies what directory to write logs.
   -L or --logfile log_file: Specifies log file.
   --home home_direcotry: Specifies pgxc_ctl work director.
   -i or --infile input_file: Specifies inptut file.
   -o or --outfile output_file: Specifies output file.
   -h or --help: Prints this message and exits.
For more deatils, refer to pgxc_ctl reference manual included in
postgres-xc reference manual.

So far, it is enough to prove OpenTenBase项目 Can be found in 如意玲珑 Compile and run successfully in the application container!

Binary program packaging & secondary distribution

Despite this, I'm still not satisfied. Another idea came up in my mind: Is there any way to export the binary files compiled in the Linyaps container and package them into deb Wait for the traditional package format to be provided to distributions that do not yet support the Linyaps environment?
Soon, I discovered that the Linyaps container contains tar procedural, combined /project The path can be mapped to the build directory of the host machine, I will $PREFIX Directories are encapsulated as archive files:

szbt@szbt-linyaps23:/project$ tar -jcvf OpenTenBase-v2.6.0-x86_64-binary.tar.bz2 $PREFIX/

OpenTenBase-v2.6.0-x86_64-binary.tar.bz2

return 普通操作 window, and found that we can also read and write this archive file through the host machine
Subsequently, I packaged the binary file in the archive file into a deb installation package, and the path was $PREFIX Modify to traditional /usr

Other distributions with similar baselines install binaries built from Linyaps containers

After getting the deb installation package, I tried it on different mainstream distributions to confirm whether the binary program built through the Linyaps container is also universal.

Summary

Obviously, not only applications packaged through the Linyaps container can be used on different distributions (need to support the Linyaps environment). Binary programs compiled through the Linyaps container can also be used on different distributions that meet the runtime requirements (the Linyaps environment is not supported yet)
