Synopsis - Cross-Reference

  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.
 17CC= gcc
 18CXX=g++
 19# Needed only for "make c++", which adds the c++ interface

 21CFLAGS= -O -DALL_INTERIOR_POINTERS
 22# Setjmp_test may yield overly optimistic results when compiled
 23# without optimization.
 24# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
 25#   altered stubborn objects, at substantial performance cost.
 26# -DFIND_LEAK causes the collector to assume that all inaccessible
 27#   objects should have been explicitly deallocated, and reports exceptions
 28# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
 29#   (Clients should also define SOLARIS_THREADS and then include
 30#   gc.h before performing thr_ or GC_ operations.)
 31# -DALL_INTERIOR_POINTERS allows all pointers to the interior
 32#   of objects to be recognized.  (See gc_private.h for consequences.)
 33# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
 34#   usually causing it to use less space in such situations.
 35#   Incremental collection no longer works in this case.
 36# -DDONT_ADD_BYTE_AT_END is meaningful only with
 37#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
 38#   causes all objects to be padded so that pointers just past the end of
 39#   an object can be recognized.  This can be expensive.  (The padding
 40#   is normally more than one byte due to alignment constraints.)
 41#   -DDONT_ADD_BYTE_AT_END disables the padding.
