Re: [Discuss-gnuradio] Windows Port Error

[Robert Roberts]

Thanks for your response!


I did not build the GNURadio code from source. I am attempting to use 
the prepackaged installers found on Martins website:

http://www.olifantasia.com/pub/projects/gnuradio/mdvh/mingw/binary-
installer/gnuradio-with-usrp/

Following his instructions I got that error below.   It does not 
appear that the test_vmcircbuf.exe program is included.


My goal is to get all of the necessary files put together onto an .iso 


I am running Windows XP SP2 on a AMD Opteron 250 (2.41 GHz), 2.75GB 
RAM, 1.2 TB of HDD space.  I also have the system running Redhat FC4 
and GNURadio works in that setting. I would ideally like to get 
GNURadio/usrp working in Windows for my purposes but don't seem to 
have good luck with it.


Thanks for your help!
