### Makefile for building and installing LCLint 2.5
###
### Updated for LCLint 2.5:  23 May 2000
### Updated for LCLint 2.4:  12 April 1998
### Updated for LCLint 2.2:  25 August 1996
### Updated for LCLint 2.1a: 17 April 1996
### Updated for LCLint 2.0:  24 February 1996
### Updated for LCLint 1.4:  29 January 1995
### Original for LCLint 1.0: 20 February 1994
###

###
### This makefile assumes the gnu version of make is available.
###
### Run: make 		to build LCLint.
###      make install   to install.
###
###
### These constants will be compiled into the lclint binary.  
###
### They may be overridden by environment variables, but these
### constants set the default values when no environment variables
### are set.
###

### Command to run C preprocessor:

DEFAULT_CPPCMD  = @CPP@

### Directory containing system include files:

SYSTEM_LIBDIR   = "/usr/include"

###
### Select installation directories:
###
### The LIBDIR and IMPORTSDIR are compiled into the binary to 
### select the default LARCH_PATH and LCLIMPORTDIR, which can 
### also be overridden by environment variables.
### 

### directory for lclint libraries
LIBDIR     = @installdir@/lib

### directory for lclint standard imports
IMPORTSDIR = @installdir@/imports

### directory for lclint binary
INSTALLDIR = @installdir@/bin

### this should be the complete path for the directory where this
### Makefile is, with no trailing / or spaces.

BASEDIR = @cwdir@

###
### Then, run:
###
###	make
###
### I recommend doing this in an emacs shell (or buffered terminal) so
### you can scroll through the output.
###
### This should (hopefully) work on most systems without further changes.
###
### If you do not have gcc, set CC = cc (or some other compiler)
### later in this file. 
###
### It should:
###     o build lclint
###     o put lclint in BASEDIR/bin/lclint
###
### If you have installed the test suite, then do:
###
###	make test
###
### to verify lclint.
###

###
### shell --- should work with /bin/sh or similar shells too.
###

SHELL  = /bin/csh

###
### If you wish to install lclint in some other directory, set these 
### variables, and do 
###
###	make install
###

### installation command
INSTALL      = @INSTALL@
INSTALLFLAGS =           

### this works with nfs, change to whatever is needed to make
### a file executable on your system

MAKEEXE = chmod 755

###
### end of installation variables
###

###
### compiler --- gcc is recommended, but lclint has been compiled
###              without changes using cc on several platforms.
###

CC = @CC@ @DEFS@

###
### optimizing compiler --- add optimization flags here
### 

CCOPT = $(CC) @OPT@

###
### link flags --- this links the lex or flex library
###

LINKFLAGS = @LINKLEX@

###
### do you have bison and/or flex?
### (Note: yacc will probably not work; lex might work but is not recommended.)
###

BISON     = @BISON@
FLEX      = @FLEX@

###
### is the test suite available? (must be full path here)
###

TESTDIR   = $(BASEDIR)/test

### 
### if this Makefile is used with one of the
### standard installation packages, no changes should be 
### necessary below this line.
###

.PHONY: install dobinaries dolibraries doimports test 

###
### set this to a different directory
### to install binaries elsewhere
