For clarity I am running under Win98 using CYGWIN tools as outlined by the
instructions "LegOS0.2.4 - Instructions for installing on NT/Win9x with
Cygwin". I was looking for help on the sort command using $sort --help but
I was getting a similar error message. I just discovered that using the
option /? gave me the help for sort. This slightly confussed me because all
that I have learned about cygwin tools is that --help gives you the help.
And as I checked my system sort is also a dos command. So the dos command
is taking precedence over the cygwin command. I have fixed this by adding in
Makefile.common another define CYGWINTOOLPREFIX as shown below
#
# WindowsNT/Cygnwin, test against several values:
#
ifneq (,$(findstring $(OSTYPE),cygwin32 CYGWIN_NT-4.0 WindowsNT Windows_NT))
# NT
TOOLPREFIX=/cygnus/cygwin-b20/H-i586-cygwin32/bin/h8300-hms-
CYGWINTOOLPREFIX=/cygnus/cygwin-b20/H-i586-cygwin32/bin/
SED_SFLAG=i
endif
And then in the rules for building the kernel in Makefile.kernel I modified
the rule for building map files to
# how to make map files
%.map: %.coff
$(NM) $*.coff | $(CYGWINTOOLPREFIX)sort -u > $*.map
This solved my problem and solved another common issue for which I will make
another posting about. Thanks for the hint there Geoff.
