Precautions for source code Installation

When compiling and installing programs in the form of source code, you need to install the GCC compiler first. Usually, you can view the help information through./configure -- help during compilation and installation, and use -- prefix to specify the installation path. Note the following:
1. Modify the PATH environment variable to identify the path of the binary program.

Method 1: Modify the/etc/profile file and add Path = $ path:/path/to/pathname.

Method 2: create a file ending with. Sh in the/etc/profile. d/directory and add the path of the binary program to the file. For example, export Path = $ path:/usr/local/httpd/bin

2. library files

By default, the search path of the library file is/usr/lib and/lib. You need to add additional search paths in/etc/lD. so. conf. d/create a new. and add the path of the library file where the binary program is located to the new file. Use ldconfig-V to search for the library files of the binary program again.

3. header file.

By default, the search path is/usr/include. To add a file search path, the link is usually used, and the link is usually the entire directory. For example, Ln-S/usr/local/httpd/include/usr/incloude/httpd

4. Man Help File

Modify/etc/man. conf, add manpath, and add the path of the man file of the binary program to/etc/man. conf.
