[Pyusb-users] pyusb-0.4.1 for cygwin

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

Hello,

I am having problems installing PyUSB for Cygwin.

I've downloaded pyusb-0.4.1.tar.gz from:
http://pyusb.berlios.de/
http://sourceforge.net/projects/pyusb

---
Then, based on the README file, I follow the steps:

-install cygwin

-download and execute libusb-win32-filter-bin-0.1.12.1.exe from
http://libusb-win32.sourceforge.net

$ cp /cygdrive/c/Program\ Files/LibUSB-Win32/lib/gcc/libusb.a /usr/lib/
$ cp /cygdrive/c/Program Files/LibUSB-Win32/src/src/usb.h /usr/include/

$ tar -xvzf pyusb-0.4.1.tar.gz
$ cd pyusb-0.4.1
$ python setup.py install
running install
running build
running build_ext
running install_lib
running install_egg_info
Removing /usr/lib/python2.5/site-packages/pyusb-0.4.1-py2.5.egg-info
Writing /usr/lib/python2.5/site-packages/pyusb-0.4.1-py2.5.egg-info

++++++++++++++
So, the installation seems to work.
However, I try with:

$ cd samples
$ python usbenum.py
Traceback (most recent call last):
  File "usbenum.py", line 7, in <module>
    import usb
ImportError: No such file or directory

----
and it does not work.

What can be the problem?


Best regards,
DAvid

Is the usb.pyd in the site-packages file? (or usb.dll)

Probably libusb is not in your cygwin lib path. Try to run some C
program demo therein...

[Wander L. <wan...@gm...>]

Well, I would try but as I am moving to a new house, my computer is
inside a box.
You could try open a interactive python session from site-packages
directory and type:

import usb

If it works, we have a problem regarding python path. If it does not
work, try this:

ldd usb.dll

And look if at the results to check if libusb dll is found.
Let me know the results.

PS: please, reply to mailing list, your doubt could be the doubt of others... ;)

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

[Wander L. <wan...@gm...>]

Hmmm... I think this file is a libusb dependency for cygwin... I guess
this a question
to libusb guys. Would mind asking it at libusb mailing list?
