MOD_LIST:=	html id3 latex mail man rtf
#		The indexing modules you want built into index(1).  If you want
#		to index mail files and you want to be able to index HTML
#		attachments, then you need to build-in "html"; similarly, if
#		you want to be able to index RTF attachments, then you need to
#		build-in "rtf".

CHARSET_LIST:=	utf7 utf8 utf16
#		The character sets you want index(1) to be able to decode.
#		Note that "us-ascii" and "iso8859-1" are implicitly included.
#
#		If you have no intention of indexing mail or news files, then
#		you do not need utf7.
#
#		If you have no intention of indexing either mail, news, or MP3
#		files and being able to index ID3 tags containing Unicode
#		characters, then you do not need either utf8 or utf16.

ENCODING_LIST:=	base64 quoted_printable
#		The Content-Transfer-Encodings you want index(1) to be able to
#		decode only when MOD_LIST contains "mail".

## READ THIS ->	Including any character sets or encodings requires more
#		processing PER CHARACTER and therefore will be slower for ALL
#		files (not just those that are encoded).  So if you don't need
#		any character sets (other than ISO 8859-1) or encodings, do NOT
#		compile them in.

FEATURE_LIST:=	word_pos
#		The set of optional features you want built into SWISH++:
#
#		1. word_pos: Store word positions during indexing needed to do
#		   "near" searches.  Storing said data approximately doubles
#		   the size of the generated index.

# Leave the following lines alone!

#		volunteers to port the socket and multithreading code.

SEARCH_DAEMON:=	-DSEARCH_DAEMON -DMULTI_THREADED -D_REENTRANT
#		These definitions will build search(1) with the ability to run
#		in the background as a multi-threaded daemon process.  Comment
#		this out if you have no need for this feature.  Currently, the
#		daemon ability is supported only for Unix and not Windows.
#
#		In order to build with the search daemon ability, use of the C
#		global variable "errno" must be thread-safe.  This usually
#		means that "errno" is defined as a macro rather than an integer
#		variable.  Different operating systems have different ways to
#		enable this.  For example, Solaris requires that you #define
#		_REENTRANT; FreeBSD has it enabled automatically; for all other
#		operating systems, check your documentation.  (Start with
#		error(3) and intro(2).)

#
###############################################################################

AR:=		ar rv
#		The command (plus arguments) to create archive libraries;
#		usually "ar rv".

RM:=		rm -fr
#		The command to remove files recursively and ignore errors;
#		usually "rm -fr" for Unix or "erase" for Windows.

#PERL:=		/usr/local/bin/perl
#		The full path to the Perl 5 executable; usually "/bin/perl" or
#		"/usr/local/bin/perl" for Unix or "\Perl\bin\perl" for
#		Windows.

RANLIB:=	ranlib
#		The command to generate library tables-of-contents; usually
#		"ranlib".  If your OS doesn't need this done to libraries, you
#		can still leave this here since errors from this command are
#		ignored in the makefiles.

SHELL:=		/bin/sh
#		The shell to spawn for subshells; usually "/bin/sh".

STRIP:=		strip
#		The command to strip symbolic information from executables;
#		usually "strip".  You can leave this defined even if your OS
#		doesn't have it or any equivalent since any errors from this
#		command are ignored in the makefiles.

#	C++ compiler

#		The C++ compiler you are using; usually "CC" or "g++".

OPTIM:=		${CXXFLAGS}
#		The optimization level.  Many compilers allow a digit after the
#		O to specify the level of optimization; if so, set yours to the
#		highest number your compiler allows without eliciting problems
#		in the optimizer.
#
#		Using g++, -O3 under Cynwin under Windows produces bad code;
#		-O3 with 3.0 causes the optimizer to take ridiculously long and
#		use most of the CPU and memory.
#
#		If SWISH++ doesn't work correctly with optimization on, but it
#		works just fine with it off, then there is a bug in your
#		compiler's optimizer.

#		Warning flags specific to g++.  Unless you are modifying the
#		source code, you should leave this commented out.

ifdef SOLARIS
TEMPLATE_REPOSITORY:=	SunWS_cache
#		The name of the directory used as C++ template repository.
#		Using Sun's CC, this is usually "SunWS_cache".  If another
#		compiler is being used that doesn't use such a repository
#		(e.g., g++), it's harmless to leave this as-is.
