Mmmm ... Been there done that still get the undefined reference problem. This must be a Windows 7 related problem. The controller firmware gets recognized by Windows, the driver gets loaded ... But I'm unable to compile (better link) the host application.

I 'm not sure what you mean when you write about the legacy .1. I 'm using the libusb-win32-bin-1.2.2.0 distribution. Should it perhaps be located in the MinGW directory, because that isn't the case right now?

Are you using the legacy API(libusb .1)? I had compile errors when i used the stable 1.0

example software host application compiler problem

2010-10-16T14:31:11+02:00

Hi all,

I have trouble compiling the host software on a 64 bit Windows 7 system.

I downloaded MinGW installer package and installed it, I had to manualy add the path variable to be able to compile from a Programmers Notepad project. No problem there ...

Then i received messages about not being able to find the usb.h file from the libusb-win32 download so I copied the header file from the ../include directory in to the ../commandline directory and changed the include statement from to "usb.h".

When I try to compile I get:

Code:

> "make.exe" -f Makefile.windows
gcc -o set-led.exe opendevice.o set-led.o -L/MinGW/lib/libusb
opendevice.o: In function `usbGetStringAscii':

What am I doing wrong? Thanks for any input.

Koen.
