200    . By default, the sequence \R in a pattern matches any Unicode line ending
201      sequence. This is independent of the option specifying what PCRE considers to
202      be the end of a line (see above). However, the caller of PCRE can restrict \R
203      to match only CR, LF, or CRLF. You can make this the default by adding
204      --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").

253    
254    . For speed, PCRE uses four tables for manipulating and identifying characters
255      whose code point values are less than 256. By default, it uses a set of
256      tables for ASCII encoding that is part of the distribution. If you specify
257    
258      --enable-rebuild-chartables
259    
260      a program called dftables is compiled and run in the default C locale when
261      you obey "make". It builds a source file called pcre_chartables.c. If you do
262      not specify this option, pcre_chartables.c is created as a copy of
263      pcre_chartables.c.dist. See "Character tables" below for further information.
264    
265    . It is possible to compile PCRE for use on systems that use EBCDIC as their
266      character code (as opposed to ASCII) by specifying
267    
268      --enable-ebcdic
269    
270      This automatically implies --enable-rebuild-chartables (see above). However,
271      when PCRE is built this way, it always operates in EBCDIC. It cannot support
272      both EBCDIC and UTF-8.
273    
274    . It is possible to compile pcregrep to use libz and/or libbz2, in order to
275      read .gz and .bz2 files (respectively), by specifying one or both of
276    
277      --enable-pcregrep-libz
278      --enable-pcregrep-libbz2
279    
280      Of course, the relevant libraries must be installed on your system.
281    
282    . It is possible to compile pcretest so that it links with the libreadline
283      library, by specifying
284    
285      --enable-pcretest-libreadline
286    
287      If this is done, when pcretest's input is from a terminal, it reads it using
288      the readline() function. This provides line-editing and history facilities.
289      Note that libreadline is GPL-licenced, so if you distribute a binary of
290      pcretest linked in this way, there may be licensing issues.
291    
292      Setting this option causes the -lreadline option to be added to the pcretest
293      build. In many operating environments with a sytem-installed readline
294      library this is sufficient. However, in some environments (e.g. if an
295      unmodified distribution version of readline is in use), it may be necessary
296      to specify something like LIBS="-lncurses" as well. This is because, to quote
297      the readline INSTALL, "Readline uses the termcap functions, but does not link
298      with the termcap or curses library itself, allowing applications which link
299      with readline the to choose an appropriate library." If you get error
300      messages about missing functions tgetstr, tgetent, tputs, tgetflag, or tgoto,
301      this is the problem, and linking with the ncurses library should fix it.

608    When the dftables program is run as a result of --enable-rebuild-chartables,
609    it uses the default C locale that is set on your system. It does not pay
610    attention to the LC_xxx environment variables. In other words, it uses the
611    system's default locale rather than whatever the compiling user happens to have

613    locale that is specified by the LC_xxx variables, you can run the dftables
614    program by hand with the -L option. For example:
