iio_utils fails on Windows

[rgetz]

This works (to validate git master tip):

C:\Users\rgetz>iio_info -s
Library version: 0.19 (git tag: 3f32d4e)
Compiled with backends: xml ip usb serial
Available contexts:
        0: 0456:b673 (Analog Devices Inc. PlutoSDR (ADALM-PLUTO)), serial=104400b839910012feff04003fe464e1b9 [usb:1.5.5]
        1: 192.168.1.127 (ad7124-4) [ip:analog-2.local]
        2: 192.168.1.120 (AD-FMCOMMS2-EBZ on Xilinx Zynq ZED (armv7l)), serial=00100 [ip:analog.local]

however:

C:\Users\rgetz>iio_attr -a usb -C
Using auto-detected IIO context at URI "usb:1.5.5"
ERROR: Bad URI: 'usb:1.5.5'

Comes from:
https://github.com/analogdevicesinc/libiio/blob/master/usb.c#L1181

This works on Linux and MAC...

[rgetz]

Ok - bisecting says:

AppVeyor says:

build 1958 - works

build 1959 - fails:
https://ci.appveyor.com/project/analogdevicesinc/libiio/builds/32634100/artifacts
rgetz-dont-ignore-sign-differences 30ebfb4

30ebfb4

1959 - fails

[rgetz]

Ok - I have a fix for that, but libiio build with MSVC crashes, with ming - it works. Still poking at that (and trying to make it easier for others to do the same).

[rgetz]

iio_info -a on my Win10 machine now causes libiio to crash.

All I get is:

C:\Users\rgetz>iio_info -a
Library version: 0.19 (git tag: bae0e60)
Compiled with backends: xml ip usb serial

and then:

just scanning works:

C:\Users\rgetz>iio_info -s
Library version: 0.19 (git tag: bae0e60)
Compiled with backends: xml ip usb serial
Available contexts:
        0: 0456:b673 (Analog Devices Inc. PlutoSDR (ADALM-PLUTO)), serial=104400b839910012feff04003fe464e1b9 [usb:1.5.5]

        2: 192.168.1.127 (ad7124-4) [ip:analog-2.local]

and connecting by hand works:

C:\Users\rgetz>iio_info -a usb:

or

C:\Users\rgetz>iio_info -u usb:1.5.5

it's only iio_info -a with multiple devices attached.

on other applications, it functions properly...

C:\Users\rgetz>iio_attr -a -C

The last part was fixed with #538 - Everything is working on Windows/MSVC again...
