Re: [Pyusb-users] pyusb-0.4.1 for cygwin

[David P. C. <dav...@gm...>]

Hello again Wander,

Here it is what I tried:
$ cd /usr/lib/python2.5/site-packages/
$ echo "import usb" >test.py
$ python test.py
Traceback (most recent call last):
  File "test.py", line 1, in <module>
    import usb
ImportError: No such file or directory

It doesn't like as a python path problem.
There is not ldd in cygwin, but I found an alternative ldd.sh here:
http://lassauge.free.fr/cygwin/archive.htm

$ ldd.sh /usr/lib/python2.5/site-packages/usb.dll
C:\cygwin\lib\python2.5\site-packages\usb.dll
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
Error: could not find cygusb0.dll
  C:\cygwin\bin\libpython2.5.dll

It has a problem finding "cygusb0.dll".
any idea?

I looked for such a file:
$ find / | grep -i .*usb.*dll.*
here some relevant results:
/cygdrive/c/WINDOWS/system32/libusb0.dll
/lib/python2.5/site-packages/usb.dll
/usr/lib/python2.5/site-packages/usb.dll

and
$ find /  | grep -i ".*usb.*\.a.*"
/cygdrive/c/Program Files/LibUSB-Win32/lib/gcc/libusb.a
/lib/libusb.a
/lib/w32api/libusbcamd.a
/lib/w32api/libusbcamd2.a
/usr/lib/libusb.a
/usr/lib/w32api/libusbcamd.a
/usr/lib/w32api/libusbcamd2.a


but not cygusb0.dll file found.


Regards,
DAvid
