PCRE is written in C, and it has its own API. There are three sets of functions,
one for the 8-bit library, which processes strings of bytes, one for the
16-bit library, which processes strings of 16-bit values, and one for the 32-bit
library, which processes strings of 32-bit values. The distribution also
includes a set of C++ wrapper functions (see the pcrecpp man page for details),
courtesy of Google Inc., which can be used to call the 8-bit PCRE library from
C++.
In addition, there is a set of C wrapper functions that are based on the POSIX
regular expression API (see the pcreposix man page). These end up in the
library called libpcreposix. Note that this just provides a POSIX calling
interface to PCRE; the regular expressions themselves still follow Perl syntax
and semantics. The POSIX API is restricted, and does not give full access to
all of PCRE's facilities.

Building PCRE on non-Unix-like systems
--------------------------------------
For a non-Unix system, please read the comments in the file NON-UNIX-USE,
though if your system supports the use of "configure" and "make" you may be
able to build PCRE in the same way as for Unix-like systems. PCRE can also be
configured in many platform environments using the GUI facility of CMake's
CMakeSetup. It creates Makefiles, solution files, etc.
For a non-Unix-like system, please read the comments in the file
NON-AUTOTOOLS-BUILD, though if your system supports the use of "configure" and
"make" you may be able to build PCRE using autotools in the same way as for
many Unix-like systems.
PCRE can also be configured using the GUI facility provided by CMake's
cmake-gui command. This creates Makefiles, solution files, etc. The file
NON-AUTOTOOLS-BUILD has information about CMake.
PCRE has been compiled on many different operating systems. It should be
straightforward to build PCRE on any system that has a Standard C compiler and
library, because it uses only Standard C functions.
Building PCRE on Unix-like systems

Building PCRE without using autotools
-------------------------------------
The use of autotools (in particular, libtool) is problematic in some
environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
file for ways of building PCRE without using autotools.
Building PCRE using autotools
-----------------------------
If you are using HP's ANSI C++ compiler (aCC), please see the special note
in the section entitled "Using HP's ANSI C++ compiler (aCC)" below.
The following instructions assume the use of the widely used "configure, make,
make install" process. There is also support for CMake in the PCRE
distribution; there are some comments about using CMake in the NON-UNIX-USE
file, though it can also be used in Unix-like systems.
The following instructions assume the use of the widely used "configure; make;
make install" (autotools) process.
To build PCRE on a Unix-like system, first run the "configure" command from the
PCRE distribution directory, with your current directory set to the directory
where you want the files to be created. This command is a standard GNU
"autoconf" configuration script, for which generic instructions are supplied in
the file INSTALL.

. If you want to suppress the building of the C++ wrapper library, you can add
--disable-cpp to the "configure" command. Otherwise, when "configure" is run,
it will try to find a C++ compiler and C++ header files, and if it succeeds,
it will try to build the C++ wrapper.

by adding one of these options to the "configure" command:
--disable-shared

(See also "Shared libraries on Unix-like systems" below.)
. By default, only the 8-bit library is built. If you add --enable-pcre16 to
the "configure" command, the 16-bit library is also built. If you add
--enable-pcre32 to the "configure" command, the 32-bit library is also built.
If you want only the 16-bit or 32-bit library, use --disable-pcre8 to disable
building the 8-bit library.

large performance improvements on certain platforms, add --enable-jit to the
"configure" command. This support is available only for certain hardware
architectures. If you try to enable it on an unsupported architecture, there
will be a compile time error.
. When JIT support is enabled, pcregrep automatically makes use of it, unless
you add --disable-pcregrep-jit to the "configure" command.
. If you want to make use of the support for UTF-8 Unicode character strings in
PCRE, you must add --enable-utf8 to the "configure" command. Without it, the
code for handling UTF-8 is not included in the library. Even when included,
it still has to be enabled by an option at run time. When PCRE is compiled

. If, in addition to support for UTF-8 character strings, you want to include
support for the \P, \p, and \X sequences that recognize Unicode character
properties, you must add --enable-unicode-properties to the "configure"
command. This adds about 30K to the size of the library (in the form of a
property table); only the basic two-letter properties such as Lu are
supported.
. There are no separate options for enabling UTF-8, UTF-16 and UTF-32
independently because that would allow ridiculous settings such as requesting
UTF-16 support while building only the 8-bit library. However, the option
--enable-utf8 is retained for backwards compatibility with earlier releases
that did not support 16-bit or 32-bit character strings. It is synonymous with
--enable-utf. It is not possible to configure one library with UTF support

The RunTest script runs the pcretest test program (which is documented in its

turn, and compares the output with the contents of the corresponding testoutput
files. A file called testtry is used to hold the main output from pcretest

the test files, give its number as an argument to RunTest, for example:

were selected. For example, the tests for UTF-8/16/32 support are run only if
--enable-utf was used. RunTest outputs a comment when it skips a test.
RunTest 2
Many of the tests that are not skipped are run up to three times. The second
run forces pcre_study() to be called for all patterns except for a few in some
tests that are marked "never study" (see the pcretest program for how this is
done). If JIT support is available, the non-DFA tests are run a third time,
this time with a forced pcre_study() with the PCRE_STUDY_JIT_COMPILE option.
The first test file can also be fed directly into the perltest.pl script to
check that Perl gives the same results. The only difference you should see is
in the first few lines, where the Perl version is given instead of the PCRE
version.
The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
libraries that are enabled. If you want to run just one set of tests, call

the seventeenth, eighteenth, and nineteenth tests are run only in 16/32-bit mode.
These are tests that generate different output in the two modes. They are for
general cases, UTF-8/16/32 support, and Unicode property support, respectively.
The twentieth test is run only in 16/32-bit mode. It tests some specific
16/32-bit features of the DFA matching engine.
The twenty-first and twenty-second tests are run only in 16/32-bit mode, when the
link size is set to 2 for the 16-bit library. They test reloading pre-compiled patterns.
The twenty-third and twenty-fourth tests are run only in 16-bit mode. They are for
general cases, and UTF-16 support, respectively.
The twenty-fifth and twenty-sixth tests are run only in 32-bit mode. They are for
general cases, and UTF-32 support, respectively.
