[Discuss-gnuradio] usrp compilation

[Ramakrishnan Muthukrishnan]

I downloaded the USRP sources from the CVS.

When I compiled it, I noticed that compiler gives errors
for usr/include/linux/usbdevice_fs.h

__user etc are defined in linux/compiler.h, so that file
needs to be included before including linux/usbdevice_fs.h
The problem went away after doing this. 

Now, it again gave an error: 

g++ -DHAVE_CONFIG_H -I. -I. -I../.. -D_REENTRANT -I../../host/lib 
-I../../firmware/include -g -O2 -Wall -Woverloaded-virtual -pthread -MT fusb.lo 
-MD -MP -MF .deps/fusb.Tpo -c fusb.cc  -fPIC -DPIC -o .libs/fusb.o
fusb.cc: In function `usbdevfs_urb* alloc_urb(fusb_ephandle*, int, int, bool,
   unsigned char*)':
fusb.cc:90: error: `USBDEVFS_URB_QUEUE_BULK' undeclared (first use this
   function)
fusb.cc:90: error: (Each undeclared identifier is reported only once for each
   function it appears in.)


The problem is that USBDEVFS_URB_QUEUE_BULK is depricated and
is not used in newer kernels (2.6.x) anymore. Please see

http://wuarchive.wustl.edu/pub/linux/kernel/people/gregkh/usb/2.5/usb-core-2.5.25.patch

(The author says this particular constant is UHCI-specific and is removed
entirely).

Debian ships kernel-headers of 2.5.x (i.e 2.6) in the unstable,
and hence I cannot compile usrp.
