Well, this is just ducky. I'm posting this so it goes in the archives and maybe saves someone else a LOT of heartache.
Batch files treat incoming, unquoted equals signs as spaces! For the cross-compiling I'm doing, I have to use a .BAT file (or equivalent), because the cross-compiler is two-stage -- it generates assembler from C, then must assemble that. Thus my batch file to do the compiles gets invoked correctly as (say): -DSOMETHING=AVALUE Banana.c but the batch file sees this as: -DSOMETHING AVALUE Banana.c Quick, someone build me a time machine so I can go back and kill whoever implemented THAT (I know, get in line...)! ...phsiii -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christopher Faylor Sent: Thursday, August 28, 2008 4:33 PM To: cygwin@cygwin.com Subject: Re: Probably stupid make question On Thu, Aug 28, 2008 at 01:13:47PM -0700, Brian Dessent wrote: >Phil Smith wrote: >>We're perverting CMake and Cygwin make to use a cross-compiler for z/OS >>(IBM mainframe).
