Linux under compile and install Pcre Library

Note: If you do not have root privileges, use--prefix to specify the installation path

./configure--prefix=/home/work/tools/pcre-8.xx

======================================================

Recently learning Nginx,nginx rewrite relies on the Pcre library, so you need to compile and install the Pcre library in a Linux system. The steps are as follows:

1. Download the Pcre Package

First go to the official website to download the PCRE installation package

If you are using FTP, for: ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

If HTTP is the way: http://sourceforge.net/projects/pcre/files/pcre/

Currently the latest version for 8.32,linux corresponds to the installation package name: Pcre-8.32.tar.gz.

2. Upload the installation package to the server and unzip

Shell Code

1. [Email protected] local]# tar-zxvf pcre-8.32.tar.gz

After decompression, a folder is generated in the current directory: pcre-8.32

Shell Code

1. Drwxr-xr-x 7 1169 1169 4096 Nov :pcre-8.32

3. Configuration

Shell Code

1. [Email protected] pcre-8.32]#./configure

The console prints a summary of the PCRE configuration after the configuration is complete

Shell Code

4. Compiling

To perform a make operation:

Shell Code

1. [[email protected] pcre-8.32]# make

After compiling, you can perform a make check to test (this step is not required)

Shell Code

2. Testing Pcregrep version 8.32 2012-11-
4. Testing Pcregrep Main Features
6. Skipping Pcregrep utf-8 Tests:no utf-8 support in PCRE library
8. Testing Pcregrep NewLine Settings
10. Pass:rungreptest
12. ==================
14. All 5 tests passed
16. ==================
18. make[2]: Leaving directory '/usr/local/pcre-8.32 '
20. make[1]: Leaving directory '/usr/local/pcre-8.32 '
22. [Email protected] pcre-8.32]#

There is a sentence in the Make check result above:

Shell Code

1. Skipping Pcregrep utf-8 Tests:no utf-8 support in PCRE library

This is because the./configuration configuration did not add support for utf-8 in the previous step.

If you want to add support for Utf-8, you can add parameters to the./configuration:

Shell Code

1. [Email protected] pcre-8.32]#/configure--enable-utf8

When you're done configuring and then re-make

The make check results are performed again after make:

Shell Code

2. Testing Pcregrep version 8.32 2012-11-
4. Testing Pcregrep Main Features
6. Testing Pcregrep utf-8 features
8. Testing Pcregrep NewLine Settings
10. Pass:rungreptest
12. ==================
14. All 5 tests passed
16. ==================
18. make[2]: Leaving directory '/usr/local/pcre-8.32 '
20. make[1]: Leaving directory '/usr/local/pcre-8.32 '
22. [Email protected] pcre-8.32]#

5. Installation

Perform the Make install operation:

Shell Code

1. [[email protected] pcre-8.32]# make install

After the make install finishes, the Pcre compilation installation process is over.
