Re: [Discuss-gnuradio] Re: Intel Mac GNU Radio Install Update Soon

[Michael Dickens]

Dave - You can do all of the background install using DarwinPorts,  
but, as you found out, FFTW has some issues.  The problem is not in  
optimization, but rather in the way Apple has tweaked GCC's use of  
"pentium-pro" for the architecture.  Most files compile just fine but  
a few (4-5) need this option removed for correct compilation (with  
optimization -03 still on, which is good).

I have submitted patches to Eric to fix the .align issue - some  
compilers define that number in log2 while others use linear.  I'd be  
happy to ship you my diff's if you have time to try them out.

As of 1 week ago, there were no issues with gnuradio-core other than  
the .align and a .global issue in the same .S files in gnuradio-core/ 
src/lib/filter .  Everything compiled and installed correctly on a  
MacBook Pro.  Admittedly, Apple has released XCode 2.3 since then, so  
if you're using that version there might be an issue.  We haven't  
finished testing under XCode 2.3 yet, maybe due to lack of time.

Permissions are generally a local-computer issue, not one of how they  
are stored in the CVS or SVN repository.

I'd be willing to bet that the compile issue is some combination of  
your shell environment and LIBTOOL not working together.  -Unless-  
it's XCode 2.3, then it's most likely not a Mac-Intel issue.

I have updated my install guide < http://www.nd.edu/~mdickens/ 
GNURadio/ > to include the latest changes for FFTW to compile using  
DarwinPorts on an Intel-Mac.

I'm happy to help you debug your compile issue, probably off-list is  
best. - MLD
