crosstoll-ng 1.15.2 build still failing on Cygwin

crosstoll-ng 1.15.2 build still failing on Cygwin

[Ian Linsdell]

Hi All,

The crosstool-ng web site claims that 1.15.2  plays nicely with Cygwin now but it fails to build.

I found someone else already submitted the below patch but it has not been incorporated into crosstool-ng 1.15.2  for some reason.

I am being bombarded with people asking why crosstool-ng is failing to build on Cygwin since there is a lot
demand to cross compile from Windows(Cygwin) to the 'Raspberry Pi' board.

Please incorporate this patch so that we don't have to fix it over again in the next release of crosstool-ng.

Thank you.

Ian.

Because it breaks on non-Cygwin.

Then tell them to switch to Linux! ;-)

Seriously, doing emnbedded Linux development from a non-Linux system is
asking for trouble.

First and foremost, doing embedded-Linux without prior knowledge of the
simpler native case is like trying to fly a 747 without having enough
flying hours on the much simpler Cesna.

Second, many tools used to do Linux development really work well only
on a Linux System. Cygwin might be a good substitute for some work, but
does not really plat nicely in such cases as embedded (and thus cross)
development.

No, it breaks the build on native Linux systems. As I do not do Cygwin
(I seldom have access to a Windows machine), I can not really test.
If you want it to work, then you have to help come up with a sane patch.
