## 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).
