2 # OS/2 specific Makefile for the EMX environment
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.
7 # Rename this file "Makefile".
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.
19 # Needed only for "make c++", which adds the c++ interface
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.
47 # Redefining srcdir allows object code for the nonPCR version of the collector
48 # to be generated in different directories
