# Toplevel makefile for building the Erlang system

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

# And you'd think that this would be obvious... :-)

# OTP release
OTP = OTP-@OTP_REL@

# erts (Erlang RunTime System) version

# Include verbose output variables
include $(ERL_TOP)/make/output.mk

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

#
# The variables below control where Erlang is installed. They are
# configurable (unless otherwise stated). Some of them are best
# changed by giving special arguments to configure instead of changing
# them in this file. Note: If you change them in Makefile, instead of
# Makefile.in your changes will be lost the next time you run
# configure.
#

# prefix from configure, default is /usr/local (must be an absolute path)
prefix		= @prefix@
exec_prefix	= @exec_prefix@

# Locations where we should install according to configure. These location
# may be prefixed by $(DESTDIR) and/or $(EXTRA_PREFIX) (see below).
bindir		= @bindir@
libdir		= @libdir@

# Where Erlang/OTP is located
libdir_suffix	= /erlang
erlang_libdir	= $(libdir)$(libdir_suffix)
erlang_bindir	= $(erlang_libdir)/bin

#
# By default we install relative symbolic links for $(ERL_BASE_PUB_FILES)
# from $(bindir) to $(erlang_bindir) as long as they are both prefixed
# by $(exec_prefix) (and are otherwise reasonable). This behavior can be
# overridden by passing BINDIR_SYMLINKS=<HOW>, where <HOW> is either
# absolute or relative.
#

# $ make DESTDIR=<...> install
#
# DESTDIR can be set in case you want to install Erlang in a different
# location than where you have configured it to run. This can be
# useful, e.g. when installing on a server that stores the files with a
# different path than where the clients access them, when building
# rpms, or cross compiling, etc. DESTDIR will prefix the actual
# installation which will only be able to run once the DESTDIR prefix
# has disappeard, e.g. the part after DESTDIR has been packed and
# unpacked without DESTDIR. The name DESTDIR have been chosen since it
# is the GNU coding standard way of doing it.
#
# If INSTALL_PREFIX is set but not DESTDIR, DESTDIR will be set to
# INSTALL_PREFIX. INSTALL_PREFIX has been buggy for a long time. It was
# initially intended to have the same effect as DESTDIR. This effect was,
# however, lost even before it was first released :-( In all released OTP
# versions up to R13B03, INSTALL_PREFIX has behaved as EXTRA_PREFIX do
# today (see below).

ifeq ($(DESTDIR),)

else

$(error Both DESTDIR="$(DESTDIR)" and INSTALL_PREFIX="$(INSTALL_PREFIX)" have been set and have been set differently! Please, only set one of them)
endif
endif
endif

# $ make EXTRA_PREFIX=<...> install
#
# EXTRA_PREFIX behaves exactly as the buggy INSTALL_PREFIX behaved in
# pre R13B04 releases. It adds a prefix to all installation paths which
# will be used by the actuall installation. That is, the installation
# needs to be located at this location when run. This is useful if you
# want to try out the system, running test suites, etc, before doing the
# real install using the configuration you have set up using `configure'.
# A similar thing can be done by overriding `prefix' if only default
# installation directories are used. However, the installation can get
# sprawled out all over the place if the user use `--bindir', `--libdir',
# etc, and it is possible that `prefix' wont have any effect at all. That
# is, it is not at all the same thing as using EXTRA_PREFIX in the
# general case. It is also nice to be able to supply this feature if
# someone should have relied on the old buggy INSTALL_PREFIX.
