BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES
By default, a library called libpcre is built, containing
functions that take string arguments contained in vectors of
bytes, either as single-byte characters, or interpreted as UTF-8
strings. You can also build a separate library, called libpcre16,
in which strings are contained in vectors of 16-bit data units
and interpreted either as single-unit characters or UTF-16
strings, by adding
--enable-pcre16
to the configure command. You can also build yet another separate
library, called libpcre32, in which strings are contained in
vectors of 32-bit data units and interpreted either as single-
unit characters or UTF-32 strings, by adding
--enable-pcre32
to the configure command. If you do not want the 8-bit library,
add
--disable-pcre8
as well. At least one of the three libraries must be built. Note
that the C++ and POSIX wrappers are for the 8-bit library only,
and that pcregrep is an 8-bit program. None of these are built if
you select only the 16-bit or 32-bit libraries.
