Package Management-source code compilation and installation

Basic understanding

In a larger project, all files cannot be edited in a single file. The source code is often stored in multiple files, easy to maintain and manage in the future, so it is not easy to compile and install.

After the project is completed, the publisher of the project will typically do the following:

1. autoconf: The Configure fileis generated .

This file is primarily used to check whether the compilation environment meets the compilation requirements and define which features or features are enabled, and define the installation path.

The result is that the makefile file is generated in conjunction with makefile.in .

2,automake: Generate makefile.in file.

Steps for compiling the installation ( example of installing Python in source code)

1, unzip the source package.

Command:tar XF pkg-name

# Tar XF python-2.7.11.tgz

2, switch into the unpacking package.

3.View Configure Help information

#./configure--help

4.Execute The configure script and specify the installation path.

#./configure--prefix=/usr/local/python--sysconfdir=/etc/python.conf

Generated the makefile file

5, compile and install.

# make && make install.

Supplement:Configure script common function, (can be configured by itself)

1. Specify the installation path

--prefix=/usr/local/python

--sysconfdie=/etc/python

2. Specify the start or disable feature

--enable-feature

--disable-feature

3.Specify the functions, programs, or files on which you depend

--with-funciton

--without-function

Post-compilation work

1. Import the binary program into the system visible range:

# vim/etc/profile.d/xxx.sh

Path=/usr/local/xxx:$PATH

Export PATH

# {. | source}/etc/profile.d/xxx.sh

[Email protected] python-2.7.11]# Vim/etc/profile.d/python.sh[[email protected] python-2.7.11]#. /etc/profile.d/python.sh[[email protected] python-2.7.11]# cat/etc/profile.d/python.sh Path=/usr/local/python/bin :/usr/local/python/sbin: $PATHexport PATH

2, the header file import system is visible:

# ln-sv/usr/local/python/include//usr/include/python

[Email protected] python-2.7.11]# ln-sv/usr/local/python/include//usr/include/'/usr/include/include '/usr/ local/python/include/'

3. Import the library file

# vim/etc/ld.so.conf.d/python.conf

/usr/local/python/lib

# ldconf Let the system generate a cache of library files.

[Email protected] python-2.7.11]# vim/etc/ld.so.conf.d/python.conf[[email protected] python-2.7.11]# ldconfig[[ Email protected] python-2.7.11]# Cat/etc/ld.so.conf.d/python.conf/usr/local/python/lib

4. import the man file

# vim/etc/man.conf

Manpath/usr/local/xxx/man

Note:python does not have A man document and is not modified here.
