# This is the original manually generated Makefile.  It may still be used
# to build the collector.
#
# Primary targets:
# gc.a - builds basic library
# c++ - adds C++ interface to library
# cords - adds cords (heavyweight strings) to library
# check - prints porting information, then builds basic version of gc.a,
#       and runs some tests of collector and cords.  Does not add cords or
#       c++ interface to gc.a
# check-cpp - runs C++ test without adding C++ (and cords) interface to gc.a
# cord/de - builds dumb editor based on cords.

ABI_FLAG=
# ABI_FLAG should be the cc flag that specifies the ABI.  On most
# platforms this will be the empty string.  Possible values:
# +DD64 for 64-bit executable on HP/UX.
# -n32, -n64, -o32 for SGI/MIPS ABIs.

AS_ABI_FLAG=$(ABI_FLAG)
# ABI flag for assembler.  On HP/UX this is +A64 for 64 bit
# executables.

CC=cc $(ABI_FLAG)
# Compiler executable name.  For EMX, replace to "gcc".

CXX=g++ $(ABI_FLAG)
# Needed only for "make c++", which adds the c++ interface.

AS=as $(AS_ABI_FLAG)
# The above doesn't work with gas, which doesn't run cpp.
# Define AS as `gcc -c -x assembler-with-cpp' instead.
# Under Irix 6, you have to specify the ABI (-o32, -n32, or -64)
# if you use something other than the default ABI on your machine.

# to be generated in different directories.

# To build the collector with threads support, add to the above:
# -DGC_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
#
# To build the preload library that intercepts malloc, add:
# -DGC_USE_DLOPEN_WRAP -DREDIRECT_MALLOC=GC_malloc -fpic

# HOSTCC and HOSTCFLAGS are used to build executables that will be run as
# part of the build process, i.e. on the build machine.  These will usually
# be the same as CC and CFLAGS, except in a cross-compilation environment.
# Note that HOSTCFLAGS should include any -D flags that affect thread support.
HOSTCC=$(CC)

# For dynamic library builds, it may be necessary to add flags to generate
# PIC code, e.g. -fPIC on Linux.

# Setjmp_test may yield overly optimistic results when compiled
# without optimization.

# Look into doc/README.macros for the description of the "define arguments"
# influencing the collector configuration.
