   1 #
   2 #  OS/2 specific Makefile for the EMX environment
   3 #
   4 #  You need GNU Make 3.71, gcc 2.5.7, emx 0.8h and GNU fileutils 3.9
   5 #  or similar tools. C++ interface and de.exe weren't tested.
   6 #
   7 #  Rename this file "Makefile".
   8 #
   9
  10 # Primary targets:
  11 # gc.a - builds basic library
  12 # c++ - adds C++ interface to library and include directory
  13 # cords - adds cords (heavyweight strings) to library and include directory
  14 # test - prints porting information, then builds basic version of gc.a, and runs
  15 #        some tests of collector and cords.  Does not add cords or c++ interface to gc.a
  16 # cord/de.exe - builds dumb editor based on cords.
  17 CC= gcc
  18 CXX=g++
  19 # Needed only for "make c++", which adds the c++ interface
  20
  21 CFLAGS= -O -DALL_INTERIOR_POINTERS -DSILENT
  22 # Setjmp_test may yield overly optimistic results when compiled
  23 # without optimization.
  24 # -DSILENT disables statistics printing, and improves performance.
  25 # -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
  26 #   altered stubborn objects, at substantial performance cost.
  27 # -DFIND_LEAK causes the collector to assume that all inaccessible
  28 #   objects should have been explicitly deallocated, and reports exceptions
  29 # -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
  30 #   (Clients should also define SOLARIS_THREADS and then include
  31 #   gc.h before performing thr_ or GC_ operations.)
  32 # -DALL_INTERIOR_POINTERS allows all pointers to the interior
  33 #   of objects to be recognized.  (See gc_private.h for consequences.)
  34 # -DSMALL_CONFIG tries to tune the collector for small heap sizes,
  35 #   usually causing it to use less space in such situations.
  36 #   Incremental collection no longer works in this case.
  37 # -DDONT_ADD_BYTE_AT_END is meaningful only with
  38 #   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
  39 #   causes all objects to be padded so that pointers just past the end of
  40 #   an object can be recognized.  This can be expensive.  (The padding
  41 #   is normally more than one byte due to alignment constraints.)
  42 #   -DDONT_ADD_BYTE_AT_END disables the padding.
