Hello, I am struggling with libusbx on cygwin under Windows 8.
You shouldn't be. I tested it and it works fine (see below).
When I
"configure" and "V=1 make" I get the failed build output below. It
looks like a pthread linkage issue and I normally know how to deal with
that, but not when it is buried under automake and libtool. Any tips?
details:
- libusbx-1.0.15-rc3
- Windows 8 (64 bit)
- cygwin updated today (15 April 2013)
I have now tested this _exact_ configuration, with a fresh copy of
cygwin, and didn't see the errors you report.
The only problem I saw was with a permission denied on depcomp during
conf, which doesn't worry me too much. I'm attaching my cygwin build log
(sorry for the shitty formatting, but I don't really use this machine
for development).
By the way, are you using gcc 3 or gcc 4?
FYI I only tested gcc 4 (v4.5.3).
If you used gcc 4, I would suspect a problem with your configuration.
Also for the record, because cygwin is often problematic, I do test it
on regular basis, the platform was tested against RC1 (though that was
cywgin 1.7.15 rather than 1.7.17).
For good measure, I have also upgraded my on Windows 7 x64 (from 1.7.15
and 1.7.17) and found no issue...
C:\cygwin\home\goertzen\libusbx-1.0.15-rc3\libusb/core.c:513: undefined

Are you sure you didn't run into an issue during your install?
Considering that it's a fresh install, and I haven't been able to
reproduce it, I would say that there's a fair chance it has to do with
your environment.
As I am unable to reproduce the issue on any of the cygwin platforms I
tried, I will proceed with the 1.0.15 release as planned (i.e. *now*).
At worst, it might be a gcc v3 issue localized to cywgin, which I don't
really see as a showstopper.
