Makefile problems together with OSTYPE env variable

[Gernot Ziegler]

Hej guys !

Sorry to disturb, but I can't seem to find the fix for this one:

I am using Mandrake 9.0 beta 2 (with the make RPM make-3.79.1-10mdk) and
address@hidden root]# bash --version
bash --version
GNU bash, version 2.05a.0(1)-release (i586-mandrake-linux-gnu)
Copyright 2001 Free Software Foundation, Inc.
echo -ne "\033]0;address@hidden: ${PWD}\007"

Now my problem is rather ... simple:
I wish to use $(OSTYPE) in my Makefile, and the code I am using is
ifeq ($(strip $(OSTYPE)),linux-gnu)
        include makedefs.linux
endif

ifeq ($(OSTYPE),irix6.5)
        include makedefs.irix
endif

Bash reports
address@hidden root]# set | grep OSTYPE
OSTYPE=linux-gnu

The funny thing is that a simple "make" on my Linux machine (Not on the
IRIX, it works there with GNU make) doesn't find this OSTYPE env variable,
it reports it to be empty (e.g.
echo abc $(OSTYPE) abc
is empty, returns
abc  abc).

Another version of the above code, the classic
include makedefs.$(OSTYPE)

reports
address@hidden texmpeg]# make
Makefile:13: makedefs.: No such file or directory
make: *** No rule to make target `makedefs.'.  Stop.

There are no whitespace characters, see
address@hidden texmpeg]# echo A"$OSTYPE"A
Alinux-gnuA

but as soon as I reset the variable with
address@hidden texmpeg]# export OSTYPE=linux-gnu

it works !!

That's a real weirdie, isn't it ? ;)

Servus,
  Gernot
