Ticket #4655: remove PCRE and PCRE2 search engines.
GRegex as PCRE wrapper was introduced in GLib-2.14. PCRE was required for MC on OSes with GLib < 2.14. Currently MC requires GLib >= 2.32. Since 2.73.2 (released at 2022-07-08), GRegex is based on PCRE2. We can remove PCRE and PCRE2 from MC and use GLib only. Signed-off-by: Andrew Borodin <aborodin@vmail.ru>

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_PCRE2([bits], [action-if-found], [action-if-not-found])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Search for an installed libpcre2-8 library. If nothing was specified
|
||||
# when calling configure, it searches first in /usr/local and then in
|
||||
# /usr, /opt/local and /sw. If the --with-pcre2=DIR is specified, it will
|
||||
# try to find it in DIR/include/pcre2.h and DIR/lib/libpcre2-8. If
|
||||
# --without-pcre2 is specified, the library is not searched at all.
|
||||
#
|
||||
# If 'bits' is empty or '8', PCRE2 8-bit character support is checked
|
||||
# only. If 'bits' contains '16', PCRE2 8-bit and 16-bit character support
|
||||
# are checked. If 'bits' contains '32', PCRE2 8-bit and 32-bit character
|
||||
# support are checked. When 'bits' contains both '16' and '32', PCRE2
|
||||
# 8-bit, 16-bit, and 32-bit character support is checked.
|
||||
#
|
||||
# If either the header file (pcre2.h), or the library (libpcre2-8) is not
|
||||
# found, or the specified PCRE2 character bit width is not supported,
|
||||
# shell commands 'action-if-not-found' is run. If 'action-if-not-found' is
|
||||
# not specified, the configuration exits on error, asking for a valid
|
||||
# PCRE2 installation directory or --without-pcre2.
|
||||
#
|
||||
# If both header file and library are found, and the specified PCRE2 bit
|
||||
# widths are supported, shell commands 'action-if-found' is run. If
|
||||
# 'action-if-found' is not specified, the default action appends
|
||||
# '-I${PCRE2_HOME}/include' to CPFLAGS, appends '-L$PCRE2_HOME}/lib' to
|
||||
# LDFLAGS, prepends '-lpcre2-8' to LIBS, and calls AC_DEFINE(HAVE_PCRE2).
|
||||
# You should use autoheader to include a definition for this symbol in a
|
||||
# config.h file. Sample usage in a C/C++ source is as follows:
|
||||
#
|
||||
# #ifdef HAVE_PCRE2
|
||||
# #define PCRE2_CODE_UNIT_WIDTH 8
|
||||
# #include <pcre2.h>
|
||||
# #endif /* HAVE_PCRE2 */

#

# DESCRIPTION
|

#
|

# check for pcre lib and set PCRE_LIBS and PCRE_CFLAGS accordingly.
|
||||
#
|

# also provide --with-pcre option that may point to the $prefix of the

# pcre installation - the macro will check $pcre/include and $pcre/lib to

# contain the necessary files.
|
||||
#
|
||||
# the usual two ACTION-IF-FOUND / ACTION-IF-NOT-FOUND are supported and
|
||||
# they can take advantage of the LIBS/CFLAGS additions.
