# pcre2-config(1)

program to return PCRE2 configuration

## NAME

pcre2-config - program to return PCRE2 configuration

## SYNOPSIS

```
pcre2-config [--prefix] [--exec-prefix] [--version]
             [--libs8] [--libs16] [--libs32] [--libs-posix]
             [--cflags] [--cflags-posix]
```

## DESCRIPTION

**pcre2-config** returns the configuration of the installed PCRE2 libraries and the options required to compile a program to use them. Some of the options apply only to the 8-bit, 16-bit, or 32-bit libraries, respectively, and are not available for libraries that have not been built. If an unavailable option is encountered, the "usage" information is output.

## OPTIONS

- **--prefix**

  Writes the directory prefix used in the PCRE2 installation for architecture-independent files (*/usr* on many systems, */usr/local* on some systems) to the standard output.

- **--exec-prefix**

  Writes the directory prefix used in the PCRE2 installation for architecture-dependent files (normally the same as **--prefix**) to the standard output.

- **--version**

  Writes the version number of the installed PCRE2 libraries to the standard output.

- **--libs8**

  Writes to the standard output the command line options required to link with the 8-bit PCRE2 library (**-lpcre2-8** on many systems).

- **--libs16**

  Writes to the standard output the command line options required to link with the 16-bit PCRE2 library (**-lpcre2-16** on many systems).

- **--libs32**

  Writes to the standard output the command line options required to link with the 32-bit PCRE2 library (**-lpcre2-32** on many systems).

- **--libs-posix**

  Writes to the standard output the command line options required to link with PCRE2's POSIX API wrapper library (**-lpcre2-posix** **-lpcre2-8** on many systems).

- **--cflags**

  Writes to the standard output the command line options required to compile files that use PCRE2 (this may include some **-I** options, but is blank on many systems).

- **--cflags-posix**

  Writes to the standard output the command line options required to compile files that use PCRE2's POSIX API wrapper library (this may include some **-I** options, but is blank on many systems).
