You can use hack in Makefile to find out whether the current
platform is Windows or not. Check for SystemRoot environment
variable in this way:
ifdef SystemRoot
SYSTEM=Windows
else ifdef SYSTEMROOT
SYSTEM=Windows
else
SYSTEM=Other
endif
In non-Windows case use Unix uname command to determine current
platform (Linux, Darwin, etc).
If you don't want to force user to install MSys or Cygwin, use
Windows-shell commands instead Unix ones. Example:
ifeq ($(SYSTEM), Windows)
RM=cmd //C del
CP=cmd //C copy
else
RM=rm -f
CP=cp
endif
So you can achieve some flexibility here.
Sometimes developers write separate makefiles named windows.mak
and posix.mak, but those ones still can share common parts via
include directive.
Also you can write small build-system for your project in D
itself. Derelict uses this approach. It also allows to ensure
that D compiler was installed and works properly.
