Re: [Discuss-gnuradio] Any GR MacOS X 10.5 Intel Users?

Thomas - Thanks for the feedback; it looks from our testing as if  
Apple's 10.5.5 tweaked some internal USB parameters to tighten down  
timing or something.  Some USRPs' USB transport is "on the sloppy  
side" now compared to 10.5.4 (and previous), while others are not.   
Really not sure what the issue is, but it seems as though it's very  
few folks with the issue so I'm not going to bother investigating  
further.

Are you using SDCC 2.8.0 from MacPorts, or some other version?  If the  
latter, could you try the former?  This is reversible if it doesn't  
work ...

0) If you have SDCC 2.4.0 installed by my script, then you need to  
remove it first; else go to (1):

curl -o sdcc-2.4.0-i386_rm.sh 
http://www.nd.edu/~mdickens/GNURadio/sdcc-2.4.0-i386_rm.sh
chmod a+x sdcc-2.4.0-i386_rm.sh
sudo ./sdcc-2.4.0-i386_rm.sh

1) now update MacPorts and install its SDCC:

sudo port sync
sudo port upgrade sdcc

2) then go to your GNU Radio install trunk:

cd usrp
make clean
cd ..
make
sudo make install

3) then go and try the usrp benchmark (in gnuradio-examples/python/ 
usrp) or some other USRP / USB transfer demo / example / application.   
If it works, then I think SDCC 2.8.0 on Intel-Mac is working.  Thanks!
