cygwin and embedded linux

[Kerl, John]

Oops, should have written:

When starting to do Linux/PPC cross-development about
a year ago (my current workplace is an NT shop) I
experimented with cygwin, for some of the same reasons
as the original poster describes.  & I found that cygwin
was roughly 20x slower than Linux running on the same class
of PC (!).  I could pop the Red Hat CD in the drive and install
the actual OS, & have it up & running in half an hour
-- less time than it took to complete a single,
moderately complex compile job on cygwin.  I soon found that
                   ^^^^^^^^^^^^^^^^^^^^^
cygwin wasn't saving me any time at all.

Just because your running on Linux doesn't mean anything because your
duplicating
the environment for cross-compiling anyway. So what does it matter if cygwin
runs
the cross tools or if Linux runs them?



I'm curious ...

How many out there actually are compiling PPC code natively on a PowerPC
Linux box for their embedded devices?

If so, do you run the same development versions on your desktop?

How do you handle the FPU issues?
