yes, you're right.  I made a typo in the email.

Hi,

OK, I made those changes and then did a build.  I got a compile error 
stating "Error: Unable to find 'usrp_spi_defs.h'"

This is one of those points where I have troubles with the make files.  How 
do I change the make files so the compiler finds the h file in a directory 
under a different source tree?  Isn't top_srcdir different when I'm building 
my blocks as opposed to building gnuradio?

Also, how can I make my block library link with the library that contains 
the stuff in usrp1_source_c.cc?  I tried adding "-lusrp1" and "-l_usrp1" to 
the _sm_la_LIBADD, but neither worked.

Thanks for your help,
Hans
