# Generates the Makefile for your extension, passing along any options and
|
|
# preprocessor constants that you may have generated through other methods.
|
|
#
|
|
# The +target+ name should correspond the name of the global function name
|
|
# defined within your C extension, minus the +Init_+. For example, if your
|
|
# C extension is defined as +Init_foo+, then your target would simply be
|
|
# "foo".
|
|
#
|
|
# If any "/" characters are present in the target name, only the last name
|
|
# is interpreted as the target name, and the rest are considered toplevel
|
|
# directory names, and the generated Makefile will be altered accordingly to
|
|
# follow that directory structure.
|
|
#
|
|
# For example, if you pass "test/foo" as a target name, your extension will
|
|
# be installed under the "test" directory. This means that in order to
|
|
# load the file within a Ruby program later, that directory structure will
|
|
# have to be followed, e.g. <code>require 'test/foo'</code>.
|
|
#
|
|
# The +srcprefix+ should be used when your source files are not in the same
|
|
# directory as your build script. This will not only eliminate the need for
|
|
# you to manually copy the source files into the same directory as your
|
|
# build script, but it also sets the proper +target_prefix+ in the generated
|
|
# Makefile.
|
|
#
|
|
# Setting the +target_prefix+ will, in turn, install the generated binary in
|
|
# a directory under your <code>RbConfig::CONFIG['sitearchdir']</code> that
|
|
# mimics your local filesystem when you run <code>make install</code>.
|
|
#
|
|
# For example, given the following file tree:
|
|
#
|
|
# ext/
|
|
# extconf.rb
|
|
# test/
|
|
# foo.c
|
|
#
|
|
# And given the following code:
|
|
#
|
|
# create_makefile('test/foo', 'test')
|
|
#
|
|
# That will set the +target_prefix+ in the generated Makefile to "test".
|
|
# That, in turn, will create the following file tree when installed via the
|
|
# <code>make install</code> command:
|
|
#
|
|
# /path/to/ruby/sitearchdir/test/foo.so
|
|
#
|
|
# It is recommended that you use this approach to generate your makefiles,
|
|
# instead of copying files around manually, because some third party
|
|
# libraries may depend on the +target_prefix+ being set properly.
|
|
#
|
|
# The +srcprefix+ argument can be used to override the default source
|
|
# directory, i.e. the current directory. It is included as part of the
|
|
# +VPATH+ and added to the list of +INCFLAGS+.
