Re: [Discuss-gnuradio] The Mystery Deepens: GNU Radio on Intel-Mac

[Michael Dickens]

I've had a reply from 1 person that the "std.ihx" file -does- allow  
the Intel-Mac to work properly with the USRP<->USB<->GR transports.   
So I have kept experimenting, and come up with more statistics, but  
maybe not any better knowledge of the underlying issue.  Basically,  
most statistics point to problems with XCode 2.4 for Intel-Mac; yet  
some folks don't have functionality using XCode 2.2.1 or 2.3, so  
that's not everything.

In the mean time, if you have an Intel-Mac and want to use GNU Radio,  
you can download a -known working- pre-compiled version of SDCC  
(2.4.0) for Intel-Mac's from my GNU Radio WWW area (it's about 1.88 MB).

Here are the added "statistics":

* I can recompile SDCC 2.4.0 (via DarwinPorts, with no updates for  
along time so it things SDCC 2.4.0 is current) on the -previously  
working- MacBook Pro (MBP) using XCode 2.4, and it no longer works.   
This is "good" since it confirms that XCode is an issue as I've been  
suspecting.

* The "std.ihx" file can be moved from a PPC Mac or elsewhere, since  
it represents code to be uploaded to the FPGA (I assume).  Hence the  
easiest way to get things going on the Intel-Mac is to do a current  
SVN checkout on both that computer and some other non-Intel-Mac  
computer, then compile and install both, then move the file  
"{gr_prefix}/share/usrp/rev2/std.ihx" from the non-Intel-Mac to the  
Intel-Mac.

* I can make a tarball of (already working on the MBP) SDCC 2.4.0,  
move it to the 20" iMac, untar and install it (into /opt/local ...  
careful), and that install now works.

* I can compile SDCC on the iMac using XCode 2.3 and it won't create  
a "good" std.ihx file.  This again points to XCode not compiling SDCC  
correctly, since clearly SDCC is functional and the original code is  
the same.
