NAME
pcre-config - program to return PCRE configuration SYNOPSIS
pcre-config [--prefix] [--exec-prefix] [--version] [--libs] [--libs16] [--libs32] [--libs-cpp] [--libs-posix] [--cflags] [--cflags-posix] DESCRIPTION
pcre-config returns the configuration of the installed PCRE libraries and the options required to compile a program to use them. Some of the options apply only to the 8-bit, or 16-bit, or 32-bit libraries, respectively, and are not available if only one of those libraries has been built. If an unavailable option is encountered, the "usage" information is output. OPTIONS
--prefix Writes the directory prefix used in the PCRE 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 PCRE installation for architecture dependent files (normally the same as --prefix) to the standard output. --version Writes the version number of the installed PCRE libraries to the standard output. --libs Writes to the standard output the command line options required to link with the 8-bit PCRE library (-lpcre on many systems). --libs16 Writes to the standard output the command line options required to link with the 16-bit PCRE library (-lpcre16 on many systems). --libs32 Writes to the standard output the command line options required to link with the 32-bit PCRE library (-lpcre32 on many systems). --libs-cpp Writes to the standard output the command line options required to link with PCRE's C++ wrapper library (-lpcrecpp -lpcre on many systems). --libs-posix Writes to the standard output the command line options required to link with PCRE's POSIX API wrapper library (-lpcreposix -lpcre on many systems). --cflags Writes to the standard output the command line options required to compile files that use PCRE (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 PCRE's POSIX API wrapper library (this may include some -I options, but is blank on many systems).

NAME
PCRE - Perl-compatible regular expressions PCRE SAMPLE PROGRAM
A simple, complete demonstration program, to get you started with using PCRE, is supplied in the file pcredemo.c in the PCRE distribution. The program compiles the regular expression that is its first argument, and matches it against the subject string in its second argument. No PCRE options are set, and default character tables are used. If matching succeeds, the program outputs the portion of the subject that matched, together with the contents of any captured substrings. If the -g option is given on the command line, the program then goes on to check for further matches of the same regular expression in the same subject string. The logic is a little bit tricky because of the possibility of matching an empty string. Comments in the code explain what is going on. If PCRE is installed in the standard include and library directories for your system, you should be able to compile the demonstration pro- gram using this command: gcc -o pcredemo pcredemo.c -lpcre If PCRE is installed elsewhere, you may need to add additional options to the command line. For example, on a Unix-like system that has PCRE installed in /usr/local, you can compile the demonstration program using a command like this: gcc -o pcredemo -I/usr/local/include pcredemo.c -L/usr/local/lib -lpcre Once you have compiled the demonstration program, you can run simple tests like this: ./pcredemo 'cat|dog' 'the cat sat on the mat' ./pcredemo -g 'cat|dog' 'the dog sat on the cat' Note that there is a much more comprehensive test program, called pcretest, which supports many more facilities for testing regular expres- sions and the PCRE library. The pcredemo program is provided as a simple coding example. On some operating systems (e.g. Solaris), when PCRE is not installed in the standard library directory, you may get an error like this when you try to run pcredemo: ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory This is caused by the way shared library support works on those systems. You need to add -R/usr/local/lib (for example) to the compile command to get round this problem. AUTHOR
