###
### Makefile for OS/2 version of splint
###
### designed for use with gmake (GNU make)
###
### based on David Evans' original makefile for Unix systems automatically
###  generated by configure on a Linux system.
###
### configuration is set here and written to file config.inc included by
###  other makefiles
###
### supported compilers are:
###  emx/gcc
###  IBM VisualAge C++ 3.0
###
### other system requirements:
###  HPFS filesystem (long filenames).
###
### *NOTE*, before running "make" edit this file to fit your local settings!
### ========================================================================
###
### Commands:
###
### make all
###    builds a release version of splint from scratch using optimizations
###
### This makefile uses gmake, the gnu version of make.
###
### Run gmake to build splint.
###     gmake install to install.
###

SHELL=/usr/bin/ksh


###
### This needs to be configured:
###

### Directory containing system include files:

SYSTEM_LIBDIR = e:/usr/include

### default preprocessor command:

CPPCMD = cpp 

### directory for splint standard imports
DEFAULT_LCLIMPORTDIR = .;e:/usr/lib/splint/imports

### directory for splint libraries
DEFAULT_LARCHPATH  = .;e:/usr/lib/splint/lib

### directory for splint binary
INSTALLDIR = e:/usr/bin

### system include directory
GCC_INCLUDE_DIR = e:/usr/include

### alternate system include directory
GCC_INCLUDE_DIR2 = e:/emx/include

###
### Cosmetic stuff (goes into the executable
###

LCL_OS2 = 1
TARGET_CPU = i586
UNAME = OS/2 Warp 4 (Paulina)

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

BISON     = bison
FLEX      = flex
YFLAGS    = -v -t -d
LFLAGS    =

###
### Set automatically: splint version and date etc.
###

LCL_VERSION := $(shell grep "^VERSION" ../configure | sed "s/VERSION *= *//")
LCL_DATE := $(shell date +"%d %b %Y")
BUILD_DATE := $(shell date +"%c")
ME := $(shell whoami)
BASEDIR := $(shell (cd ..; cmd /c cd | tr '\\' '/'))

LCL_COMPILE = Compiled using $(CC)\\n on $(UNAME) $(TARGET_CPU) $(BUILD_DATE) by $(ME),\\n OS/2 specific subversion is $(LCL_OS2)
LCL_PARSE_VERSION = Splint $(LCL_VERSION)
SPLINT_VERSION = $(LCL_PARSE_VERSION) -- $(LCL_DATE)


###
### Then, run:
###
###	make
###
###

### file-related commands (I use emx GNUish utilities)
CP = cp
MV = mv
CAT = cat
RM = rm
INSTALL = cp
INSTALLFLAGS =           
ECHO = echo

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