Thanks for letting me know... I must have not been around when that
discussion was made. The statement was based off the assumption that people
would prefer to build osg in less than 5 minutes rather than a couple of
hours (which I believe is still true). The gotcha for me is that people
have had so much trouble using them.
Our company has used pre-compiled headers for 6+ years (every since VS 7),
for projects larger than this with no problems at all. It's a shame I
wasn't around during the discussions about this. I suspect the real
difference is that pre-compiled headers are too clunky for a multi-platform
environment. For this reason, I bow out gracefully for the idea.
Really though, the significant amount of time that could be saved is a
strong argument for consideration... Is the price for this really too high?
Is there anyone at all in the OSG community who has had positive experience
with pre-compiled headers?

Hi James
FYI Not using pre-compiled headers in OSG was/is a conscious choice, many
on this list will not touch pre-compiled headers with a barge pole for
various reason that have been discussed several times in the past.
In our shop the use of pre-compiled headers is totally band...
"it would make all the VS7-9 OSG developers very happy"
Bold statement speaking for every one like that :)
I'm one Vs7-9 OSG Developer that would be very annoyed if precompiled
headers were enabled :(

One convention that we use is to include stdafx.h first and then the "dll"
header file. It is too bad that OSG didn't follow this convention
otherwise; I'd pursue making a submission that turned on pre-compiled
headers (That's easy to do actually). If this were turned on, it is
possible to build projects in under a minute rather than take an hour
(Even
the OSG project). I'm not sure if other compilers have such a feature,
but
if someone wanted to take and run with this idea, it would make all the
VS7-9 OSG developers very happy.

Thanks Andy, build fixes now merged and submitted to svn. I number of
additions of stdlib.h probably comes down to clean up of OSG headers
that I did which removed unnecessary includes, this while cleaner does
push the need to include stdlib.h etc. on to more source files.

Here is a pile more. This shows how long it has been since I was
compiling
OSG regularly, and how much has gone in.
thanks
