#

#  OS/2 specific Makefile for the EMX environment

#

#  You need GNU Make 3.71, gcc 2.5.7, emx 0.8h and GNU fileutils 3.9

#  or similar tools. C++ interface and de.exe weren't tested.

#

#  Rename this file "Makefile".

#

# Primary targets:

# gc.a - builds basic library

# c++ - adds C++ interface to library and include directory

# cords - adds cords (heavyweight strings) to library and include directory

# test - prints porting information, then builds basic version of gc.a, and runs

#        some tests of collector and cords.  Does not add cords or c++ interface to gc.a

# cord/de.exe - builds dumb editor based on cords.

CC= gcc

CXX=g++

# Needed only for "make c++", which adds the c++ interface

CFLAGS= -O -DALL_INTERIOR_POINTERS -DSILENT

# Setjmp_test may yield overly optimistic results when compiled

# without optimization.

# -DSILENT disables statistics printing, and improves performance.

# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly

#   altered stubborn objects, at substantial performance cost.

# -DFIND_LEAK causes the collector to assume that all inaccessible

#   objects should have been explicitly deallocated, and reports exceptions

# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.

#   (Clients should also define SOLARIS_THREADS and then include

#   gc.h before performing thr_ or GC_ operations.)

# -DALL_INTERIOR_POINTERS allows all pointers to the interior

#   of objects to be recognized.  (See gc_private.h for consequences.)

# -DSMALL_CONFIG tries to tune the collector for small heap sizes,

#   usually causing it to use less space in such situations.

#   Incremental collection no longer works in this case.

# -DDONT_ADD_BYTE_AT_END is meaningful only with

#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS

#   causes all objects to be padded so that pointers just past the end of

#   an object can be recognized.  This can be expensive.  (The padding

#   is normally more than one byte due to alignment constraints.)

#   -DDONT_ADD_BYTE_AT_END disables the padding.
