# This is "linux.mkscript", a script which defines build settings used in
|
|
# inweb, intest, inform and all of their subsidiary tools for the platform
|
|
# "linux", used for tools compiled for use in the Gnome app. The maintainer
|
|
# of this file is Philip Chimento.
|
|
|
|
# The script is used for two purposes. Firstly, it is used to generate the
|
|
# file "linux.mk" of platform settings. If an inweb user selects linux as
|
|
# platform on a first run, then this is the file copied into place as
|
|
# inweb/platform-settings.mk. But secondly, it also defines macros which
|
|
# can be used by any *.mkscript files being converted to *.mk files on
|
|
# this platform.
|
|
|
|
# Do not edit "linux.mk" directly. Instead, edit this script, and then
|
|
# rebuild "linux.mk" by setting the current working directory to the directory
|
|
# _above_ "inweb", and using the command:
|
|
|
|
# inweb/Tangled/inweb inweb -prototype inweb/Materials/platforms/linux.mkscript -makefile inweb/Materials/platforms/linux.mk
|
|
|
|
# Or simply:
|
|
|
|
# make -f inweb/inweb.mk makers
|
|
|
|
# which recreates all of the make-files in the inweb repository from their
|
|
# scripts, including linux.mk among them.
|
|
|
|
# See the inweb manual for documentation on the *.mkscript file format, i.e.,
|
|
# the format in which this file is written. But it is essentially just a makefile
|
|
# with a number of special macro and loop features whose syntax involves braces
|
|
# { ... }, so anywhere that you see braces, you're looking at something special
|
|
# to *.mkscript; anything else is straightforward make syntax.
|
|
|

# -----------------------------------------------------------------------------
|
|
|
|
# The first definition in this file must set INWEBPLATFORM to the platform
|
|
# name, which is the same as the leafname of this file without the ".mkscript"
|
|
# file extension. So:
|
|
|
|
INWEBPLATFORM = linux
|
|
|
|
# The I6 source code has its own set of symbolic names for operating systems,
|
|
# not always the same as inweb's names for platforms, so:
|
|
|
|
INFORM6OS = LINUX
|
|
|
|
# And similarly for glulxe, which is used as part of the dumb-glulx interpreter,
|
|
# which is used in testing Inform on the command line:
|
|
|
|
GLULXEOS = OS_UNIX
|
|
|
|
# On some platforms, executables have a specific file extension, which we define here:
|
|
|
|
EXEEXTENSION =
|
|
|
|
# -----------------------------------------------------------------------------
|
|
|
|
# These are likely to be the same on all platforms:
|
|
|
|
INTEST = intest/Tangled/intest
|
|
INWEB = inweb/Tangled/inweb
|

|

|
# Now three macro definitions: two for compiling C code to *.o object files
|
|
# (one being strict about warnings, the other indulgently suppressing them);
|
|
# and one for linking those *.o files into an executable.
