preface

Linux system software generally has deb and The installation package in rpm format, that is, the Linux system uses the "red hat package manager" red hat package manager, which can be packaged rpm installation package, which is described below Production of rpm. For more information deb package production, click "Debian Packager" package manager.

Making tools

Before production, rpmbuild and rpmdevtools need to be installed in the system environment. You can install them with the following command:

yum install rpmbuild
yum install rpmdevtools

Make rpm package

Here is an rpm package for Qt development software. This function is a small program to display the current time after startup. (program code at the bottom)

1. First, execute rpmdev setuptree to generate the rpmbuild directory file. If rpmdevtools is not installed,
mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}

[root@localhost ~]# rpmdev-setuptree 
[root@localhost ~]# ls ~/rpmbuild/
BUILD  RPMS  SOURCES  SPECS  SRPMS
[root@localhost ~]#

2. Rename the directory where the program is located as: xxx-xxx-1.0 0 (xxx xxx is the name and cannot be capitalized, 1.0.0 represents the version number);
3. Execute the command tar - zcvf show-timer-1.0 0.tar.gz show-timer-1.0. 0 / compress the file to tar GZ compressed package;
4. Move the compressed file to ~ / rpmbuild/SOURCES, that is, the rpmbuild/SOURCES of the current user

[root@localhost desktop]# tar -zcvf show-timer-1.0.0.tar.gz show-timer-1.0.0/
show-timer-1.0.0/
show-timer-1.0.0/showTime.pro.user
show-timer-1.0.0/showTime.desktop
show-timer-1.0.0/main.cpp
show-timer-1.0.0/widget.ui
show-timer-1.0.0/widget.cpp
show-timer-1.0.0/widget.h
show-timer-1.0.0/showTime.pro
show-timer-1.0.0/.qmake.stash
[root@localhost desktop]# mv show-timer-1.0.0.tar.gz ~/rpmbuild/SOURCES/
[root@localhost desktop]# ls ~/rpmbuild/SOURCES/
show-timer-1.0.0.tar.gz
[root@localhost desktop]#

5. cd to ~ / rpmbuild directory and execute rpmdev newspec - O specs / show timer spec generation spec file,
Without the rpmdev newspec command, you can actually copy other packages spec to change

[root@localhost rpmbuild]# cd ~/rpmbuild/
[root@localhost rpmbuild]# rpmdev-newspec -o SPECS/show-timer.spec
SPECS/show-timer.spec created; type minimal, rpm version >= 4.15.
[root@localhost rpmbuild]# ls SPECS/
show-timer.spec
[root@localhost rpmbuild]#

6. Modification spec file

[root@localhost rpmbuild]#  vim ~/rpmbuild/SPECS/show-timer.spec
[root@localhost rpmbuild]#  cat ~/rpmbuild/SPECS/show-timer.spec
%global debug_package  %{nil}

7. Execute rpmbuild - BA specs / show timer Spec generates rpm binary package and src source package

[root@localhost rpmbuild]# ls SRPMS
show-timer-1.0.0-1.src.rpm
[root@localhost rpmbuild]# ls RPMS/x86_64/
show-timer-1.0.0-1.x86_64.rpm
[root@localhost rpmbuild]#

rpm common commands

rpm -ivh show-timer-1.0.0-1.x86_64.rpm installation
rpm -e show-timer-1.0.0-1.x86_64.rpm unloading
rpm -ivh show-timer-1.0.0-1.src.rpm will generate ~ / rpmbuild / spec / show timer spec,
Then execute rpmbuild - BP ~ / rpmbuild / spec / show timer Spec will generate ~ / rpmbuild / build / show-timer-1.0 0
Program source code
rpmbuild -bb ~/rpmbuild/SPEC/show-timer.spec only generates binary, i.e. show-timer-1.0 0-1. x86_ 64.rpm package
rpmbuild -bs ~/rpmbuild/SPEC/show-timer.spec only generates the source package, i.e. show-timer-1.0 0-1. src. RPM source package
rpmbuild -ba ~/rpmbuild/SPEC/show-timer.spec generates binary and source packages

rpmbuild directory introduction

[root@localhost rpmbuild]# ls
BUILD  BUILDROOT  RPMS  SOURCES  SPECS  SRPMS
[root@localhost rpmbuild]#

BUILD: execute rpmbuild - BP ~ / rpmbuild / spec / show timer The source code generated by spec is in this directory
BUILDROOT: This is a temporary build directory, which can be ignored
RPMS: the generated binary package is in this directory
SOURCES: the compressed source package and other source files are in this directory
SPECS: . The spec configuration file is in this directory
SRPMS: the generated source package is in this directory
