A few files have other copyright holders. A few of the files needed
to use the GNU-style build procedure come with a modified GPL license
that appears not to significantly restrict use of the collector, though
use of those files for a purpose other than building the collector may
require the resulting code to be covered by the GPL.
For more details and the names of other contributors, see the
README file and gc.h. This file describes typical use of
doc/README* files and include/gc.h. This file describes typical use of
the collector on a machine that is already supported.
INSTALLATION:
Under UN*X, type "make test". Under OS/2 or Windows NT, copy the
appropriate makefile to MAKEFILE, read it, and type "nmake test".
Read the machine specific README if one exists. The only way to
develop code with the collector for Windows 3.1 is to develop under
Windows NT, and then to use win32S.
For the version number, see doc/README or version.h.

INSTALLATION:
Under UN*X, Linux:
Alternative 1 (the old way): type "make test" in this directory.
Link against gc.a.
Alternative 2 (the new way): type
"./configure --prefix=<dir>; make; make check; make install".
Link against <dir>/lib/libgc.a or <dir>/lib/libgc.so.
See README.autoconf for details
Under OS/2 or Windows 95, 98, Me, NT, or 2000:
copy the appropriate makefile to MAKEFILE, read it, and type "nmake test".
(Under Windows, this assumes you have Microsoft command-line tools
installed, and have DOS configured with enough environment space to run them.)
Read the machine specific README in the doc directory if one exists.
The only way to develop code with the collector for Windows 3.1 is
to develop under Windows NT or 95+, and then to use win32S.
If you need thread support, you will need to either follow the special
platform-dependent instructions (win32), or add a suitable define
option as described in Makefile.
If you wish to use the cord (structured string) library, type
"make cords". (This requires an ANSI C compiler. You may need
to redefine CC in the Makefile.)
to redefine CC in the Makefile. The CORD_printf implementation in
cordprnt.c is known to be less than perfectly portable. The rest
of the package should still work.)
If you wish to use the collector from C++, type
"make c++". These add further files to gc.a and to the include
subdirectory. See cord/cord.h and gc_c++.h.
subdirectory. See cord/cord.h and include/gc_cpp.h.
TYPICAL USE:
Include "gc.h" from this directory. Link against the appropriate library
("gc.a" under UN*X). Replace calls to malloc by calls to GC_MALLOC,
and calls to realloc by calls to GC_REALLOC. If the object is known
to never contain pointers, use GC_MALLOC_ATOMIC instead of
GC_MALLOC.
Include "gc.h" from the include subdirectory. Link against the

by calls to GC_MALLOC, and calls to realloc by calls to GC_REALLOC.
If the object is known to never contain pointers, use GC_MALLOC_ATOMIC
instead of GC_MALLOC.
Define GC_DEBUG before including gc.h for additional checking.
More documentation on the collector interface can be found at
http://www.hpl.hp.com/personal/Hans_Boehm/gc/gcinterface.html,
in doc/README, and in include/gc.h .
WARNINGS:
Do not store the only pointer to an object in memory allocated
with system malloc, since the collector usually does not scan
memory allocated in this way.
Use with threads may be supported on your system, but requires the
collector to be built with thread support. See Makefile. The collector
does not guarantee to scan thread-local storage (e.g. of the kind
accessed with pthread_getspecific()). The collector does scan
thread stacks though, so generally the best solution is to ensure that
any pointers stored in thread-local storage are also stored on the
thread's stack for the duration of their lifetime.
