# Make file for PCRE (Perl-Compatible Regular Expression) library.

# If you are using a Unix system, see below.

##############################################################################
# If you want to compile PCRE for a non-Unix system, note that it consists
# entirely of code written in Standard C, and so should compile successfully
# using normal compiling commands to do the following:
#
# (1) Compile dftables.c as a stand-alone program, and then run it with
# output sent to chartables.c. This generates a set of standard character
# tables.
#
# (2) Compile maketables.c, get.c, study.c and pcre.c and link them all
# together. This is the pcre library (chartables.c gets included by means of
# an #include directive).
#
# (3) Compile pcreposix.c and link it as the pcreposix library.
#
# (4) Compile the test program pcretest.c. This needs the functions in the
# pcre and pcreposix libraries when linking.
#
# (5) Run pcretest on the testinput files, and check that the output matches
# the corresponding testoutput files. You must use the -i option with
# testinput2.

# On a Unix system:
#
# Edit CC, CFLAGS, and RANLIB for your system.
#
# It is believed that RANLIB=ranlib is required for AIX, BSDI, FreeBSD, Linux,
# MIPS RISCOS, NetBSD, OpenBSD, Digital Unix, and Ultrix.
#
# Use CFLAGS = -DUSE_BCOPY on SunOS4 and any other system that lacks the
# memmove() function, but has bcopy().
#
# Use CFLAGS = -DSTRERROR_FROM_ERRLIST on SunOS4 and any other system that
# lacks the strerror() function, but can provide the equivalent by indexing
# into errlist.

CC = gcc -O2 -Wall
CFLAGS =
RANLIB = @true

# If you are going to obey "make install", edit these settings for your
# system. BINDIR is the directory in which the pgrep command is installed.
# INCDIR is the directory in which the public header file pcre.h is installed.
# LIBDIR is the directory in which the libraries are installed. MANDIR is the
# directory in which the man pages are installed. The pcretest program, as it
# is a test program, does not get installed anywhere.
