Yes that works, however it would be nice to be able to use the (f) version of the common math functions when they are available in that they **maybe** faster depending on the machine compiler combination. AFAIK This was part of the rationale behind their addition to the C99 standard Cheers Norman > > -Original Message- > > From: Bernie Bright [mailto:[EMAIL PROTECTED]] > > Sent: 24 September 2002 10:34 am > > To: [EMAIL PROTECTED] > > Subject: Re: [Flightgear-devel] MSVC 6.0 Problem with > > systems/vacuum/vacuum.cxx > > > > > > On Tue, 24 Sep 2002 03:46:54 -0400 > > "Norman Vine" <[EMAIL PROTECTED]> wrote: > > > > > Bernie Bright writes: > > > > > > > On Mon, 23 Sep 2002 18:51:25 -0700 > > > > Jonathan Polley <[EMAIL PROTECTED]> wrote: > > > > > > > > > MSVC does not have fmin() defined, so complains in vacuum.cxx. > > > > > > > > > > > > > gcc 2.95.3 complains too. fmin() is only defined if > > _ISOC99_SOURCE is > > > defined before including . > > > > > > I wonder if we are going to need a sg_math.h > > > if so here is a first stab at one > > > > > [cut] > > > > Well, as far as I can tell, fmin() is C99 not Std C++.

And so it goes on... My fault -- I didn't realize that fmin() was non-ANSI. I've fixed it in the CVS (in advance of integration of Alex's vacuum model from steam.cxx).

I changed my copy to use min() rather than fmin() (W2K, cygwin, gcc version 2.95.3-5 (cygwin special)). Builds, links, and appears to run OK.

We could use std::min() but that causes a problem with MSVC where you have to use cpp_min() instead. And so it goes on...

MSVC does not have fmin() defined, so complains in vacuum.cxx. Thanks, Jonthan Polley Of COURSE they can do that. They're engineers! ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
