Hello, I am struggling with libusbx on cygwin under Windows 8. 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 am making a USB device from a LPC11u24 and want to talk to it via
libusbx.
Thanks,
Dan.
