# MAKEFILE for MS Windows (mingw + gcc + gmake)
#
# BEWARE: variable OBJECTS is updated via helper.pl

### USAGE:
# Open a command prompt with gcc + gmake in PATH and start:
#
# gmake -f makefile.mingw all
# test.exe
# gmake -f makefile.mingw PREFIX=c:\devel\libtom install

#The following can be overridden from command line e.g. make -f makefile.mingw CC=gcc ARFLAGS=rcs
PREFIX    = c:\mingw
CC        = gcc
AR        = ar
ARFLAGS   = rcs
STRIP     = strip
CFLAGS    = -O2
LDFLAGS   =

#Compilation flags

#Libraries to be created
LIBMAIN_S =libtommath.a
