After hearing from a few OSX users this afternoon at GRCon14 that they  
were having issues getting gr-mac to build or function, I decided to get  
it into MacPorts. Thus, after a little work and a couple patches, it is  
now in and seemingly functional as of r125409 \<  
[Changeset 125409 – MacPorts](https://trac.macports.org/changeset/125409) \> and will be live as of  
about 11:30 PM/US/Eastern. To get this module, you’ll want to do:  
{{{  
sudo port selfupdate  
}}}  
and then you can install it via:  
{{{  
sudo port install gr-mac  
}}}  
Please follow the install instructions provided at the end of the  
install:  
{{{  
±------------------------  
| Before gr-mac will work correctly, you will need to execute  
|  
| /opt/local/bin/grcc /opt/local/share/examples/mac/gmsk\_radio.grc  
|  
| and  
|  
| /opt/local/bin/grcc /opt/local/share/examples/mac/ofdm\_radio.grc  
|  
| as the user for which you want to use gr-mac.  
±------------------------  
}}}

Have fun! - MLD

Michael,

Thanks for the rapid response!

Did a sync and tried installing it, and got the following  
error while it was working off the dependencies:

Ed and I talked off-list, but for those interested this type of error  
generally means that the installed version of MacPorts is too old and  
needs updating. In this specific case, “configure.cxx\_stdlib” was added  
in the 2.3 release. Thus, if the dports tree was updated but ‘port’ was  
not, then this error would be produced. - MLD
