# This Makefile can be used explicitly with make, or it can be used to install the
# plugin API with buildit.

# When used explicitly with make the following targets are available:

# all		Build the entire MacsBug plugin tree and its gdb plugin API.
# clean		Clean both the MacsBug and API objects and plugin.

# The following defines may be set on the make line:

# SRCROOT	Which directory the API sources are in (default is .).

# SYMROOT	Target directory to contain API LIBRARY (gdb_plugin_support.o, default
#		is .).

# OBJROOT	Directory to contain the Objects/ directory, i.e., where .o's go,
#		default is ./Objects).

# When this Makefile is used with buildit BUILDIT_DIR should be set to where buildit
# is to create its output.  Buildit expects and uses the following targets:

# installsrc	Installs all the source and additional files for the build into
#		SRCROOT.  Use buildit's -noinstallsrc to suppress the source copy.

# clean		Clean API objects.  Use buildit's -noclean to suppress the clean step.

# installhdrs	Installs the API header (gdb.h) into DSTROOT which is defined by buildit. 
#		Currently the following layout describes where the default install places
#		the header:

#		/usr/include/gdb/gdb.h

# install	Installs the API static library into DSTROOT which is defined by buildit.
#		Currently the following layout describes where the default install places
#		the files:

# 		/usr/lib/gdb/gdb_plugin_support.o

# As a reminder here some other possibly "useful" buildit options: -noverify, -nosum.

#--------------------------------------------------------------------------------------#

# NOTE: THE API IS NOT YET RELEASED SEPARATELY.  THUS THE BUILDIT TARGETS ARE NOT BEING
#       USED.  CURRENTLY THIS MAKEFILE IS USED SOLELY BY THE MACSBUG MAKEFILE EXPLICITLY.
#	THUS THE LIBRARY IS PLACED WHERE THE MACSBUG MAKEFILE WANT'S IT AND THE HEADER
#	IS KEPT IN THE API'S SOURCE DIRECTORY AND NOT INSTALLED ANYWHERE.
