If this is failing it looks more like a autoconf issue - what is the output
of configure?
You are right. The different between the MinGW 32bit and MinGW-w64
64bit build is that the option is different.
For MinGW 32bit build:
/* Support FT2232H/FT4232HS with FTD2XX or libftdi. */
#define BUILD_FT2232_HIGHSPEED 1
For MinGW-w64 64bit build
/* Support FT2232H/FT4232HS with FTD2XX or libftdi. */
/* #undef BUILD_FT2232_HIGHSPEED */
That part of configure checks for TYPE_2232H being defined.
It uses ftdi.h as its include which in turn includes usb.h - whichever
one it finds first.
If mingw-64 are already using usb.h then that creates a bit of a problem
for any interface that is expecting libusb usb.h.
The only safe solution would be to use a subdirectory for libusb/libftdi
if mingw64 will not change their layout.
Cheers
