This article focuses on "Linux source package compilation and installation methods", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn the "Linux source package compilation and installation method" bar!

The use of the source code is nothing more than the following two points

1. The software is customized according to the needs of users.

2. Secondary development; Note: the developer must license the secondary development according to the license agreement of the software.

LINUX is open source, look at how stubborn everyone is, ha ha, well, the following text begins, I sent it to bed!

1. The packaging format of the source package

The source code is generally packaged in file.tar.gz file.tar.bz2 or file.src.rpm; the unpacking commands in file.tar.gz and file.tar.bz2 formats are as follows

[root@localhost beinan] # tar jxvf file.tar.bz2

[root@localhost beinan] # tar zxvf file.tar.gz

When we unpack a package and enter the unzipped package, we can usually find README (or reame) and INSTALL (or install); or doc (or DOC) directory; just look at the name and know something similar.

For example, we download a relatively new fcitx software package, such as fcitx-3.2-050827.tar.bz2.

When we unlock this package, we will find the following files

[root@localhost fcitx] # tar jxvf fcitx-3.2-050827.tar.bz2

[root@localhost fcitx] # cd fcitx

[root@localhost fcitx] # ls

Aclocal.m4 config.guess configure debian INSTALL Makefile.in src xpm

AUTHORS config.h.in configure.in depcomp install-sh missing THANKS

Autogen.sh config.rpath COPYING doc lib mkinstalldirs TODO

ChangeLog config.sub data fcitx.spec.in Makefile.am README tools

So we can look at the installation documentation of fcitx's INSTALL and doc directories; it all tells us how to install

Sometimes the installation documentation will have detailed instructions on the developer's home page, as well as the handling of common problems, such as LumaQQ

2) conditions for compiling and installing software

First of all, we have to install at least development tools in the Linux system, such as gcc; perl;python;glibc;gtk;make; automake and other development tools or basic packages; and also install some corresponding development packages, usually with file names including dev, such as kernel-devel; and some development libraries, such as those that begin with lib. If you are sometimes prompted to lack something when compiling software, the bigger ones are these development tools and libraries, etc.; just find out the installation from the CD; sometimes the CD is not provided, please use google to search for the corresponding software package, and sometimes you may use the package that the source package compilation and installation depends on.

Sometimes the dependent package is already installed in the system, but the system prompts me what to do if I can't find it. At this point, we just need to set the environment variable of PKG_CONFIG_PATH.

# export PKG_CONFIG_PATH=/usr/lib/pkgconfig

Or

# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

And then we'll run the compiled. / configure; make; make install, try it.

Programs developed with tools developed by java use jre or jdk; jdk already includes jre, so if we just ask for an environment in which java programs run, we only need to install jre; install jre and configure the environment variables of java can be used. If it is a graphical interface program, a click of the mouse will OK.

Programs developed with perl require a perl environment, so you have to install the perl package, and so does python.

3) the method of compiling and installing software

Most of the software is packaged in tar.gz and tar.bz2, mostly installed through. / configure; make;make install; some software is directly make;make install

We can check the function of the configuration software through. / configure-- help; most software provides the function of. / configure configuration software; a few do not, if not, do not use. / configure; just make;make install it

. / configure one of the more important parameters is-- prefix, with the-- prefix parameter, we can specify the software installation directory; when we do not need this software, just delete the software directory

For example, we can specify that fcitx is installed in the / opt/fcitx directory

[root@localhost fcitx] #. / configure-prefix=/opt/fcitx

If we don't need fcitx, we can delete the / opt/fcitx directory directly.

So in this example, if fcitx is customized and installed into the / opt/fcitx directory, the complete installation method should be:

[root@localhost fcitx] # tar jxvf fcitx-3.2-050827.tar.bz2

[root@localhost fcitx] # cd fcitx

[root@localhost fcitx] #. / configure-prefix=/opt/fcitx

[root@localhost fcitx] # make

[root@localhost fcitx] # make install

Call fcitx, which should be

[beinan@localhost ~] # / opt/fcitx/bin/fcitx

If you want fcitx to call simply by executing fcitx, configure the environment variable, or make a link to fcitx in / usr/bin

[root@localhost beinan] # ln-s / opt/fcitx/bin/fcitx / usr/bin/fcitx

In general, it is said, but most software does not provide a method to uninstall the source package; we can find the installation point of the software to delete. It mainly depends on where you install it.

Set the environment variable PATH. I won't talk much nonsense about this. Everyone should know it.

Your PATH can be set up like this

Export PATH= ".: / bin:/usr/bin:/usr/local/bin:/usr/sbin:/usr/X11R6/bin:/sbin:/opt/fcitx/bin"

For example, for example, I want to install mlterm; and specify the installation directory as / opt/mlterm; http://mlterm.sourceforge.net

#. / configure-prefix=/opt/mlterm

# make

# make install

Specify that the software installed by the source package is installed in the / opt directory, so that you will not only know where the software is installed; it is also convenient to uninstall

At this point, I believe that everyone on the "Linux source package compilation and installation method" have a deeper understanding, might as well to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
