XCode / SDCC Intel-Mac issue

I made enough progress on this issue to know there is a problem, but
that it’s beyond what I can investigate further until I have more time.

What I’m doing instead is making the compiled and ready to install
SDCC 2.4 for Intel-Darwin available for anyone to download and
install. That way folks can keep using GNU Radio from the current
SVN repository, and at some time in the future maybe SDCC will get
fixed, or Apple’s GCC will get fixed, or whatever the problem(s) is
(are) will get fixed. While XCode certainly seems suspicious, and
most fingers point to it being the issue, some fingers don’t point
there (they just don’t point, since those data points don’t fit into
any pattern I’ve tested).

I’ve updated the “MacInstall” Wiki page with this info < http://
gnuradio.org/trac/wiki/MacInstall >. I’m also updating my install
guide with the same info. I would certainly appreciate knowing that
this work around does really work for (some, all, many) Intel-Mac
users. I know that it works for me. - MLD

Michael,

thank you for doing an excellent piece of detective work to get to the
source of this issue! Well done! I’ll be at ND for “The Game” next
weekend, and if you happen to go there too, I’d like to buy you a hot
dog!

I have another surprising data point to add to this whole thing: I just
updated all the darwinports stuff on my wife’s Macbook Pro. I rebuilt
the world, and guess what, the USRP code builds and runs just fine on
that machine with SDCC 2.6! This is with XCode 2.2.1. I seem to have
gotten the lucky release. Maybe not all the 2.2.1s are the same
(different gcc builds or something)? Mine came from the DVD in the box.

Anyway, thanks for all the time you sank into this. At least now
everybody should be able to build a working USRP image on any of the
Intel Macs, and that’s what matters.

Cheers,
Jan

Fascinating. Maybe 2.2.1 was what was running on the MBP from which
I retrieved the “good” SDCC 2.4.0. I will have to revert back the
MBP (from 2.4 to 2.2.1) and the Intel-iMac further (from 2.3 to
2.2.1) and see if that makes any difference - hopefully Monday (Oct 16).

I was able to boil down the runtime error in SDCC 2.6.0 (i.e.
compiling C code into FPGA code using SDCC) using about 30 lines of
GR code. I’ve submitted the various findings including that code
(with FSF header) to the DarwinPorts folks, who seem intrigued.

Anyway, thanks for all the time you sank into this. At least now
everybody should be able to build a working USRP image on any of

You and the general GR community (esp OSX users) are welcome; it
continues to be a goal of mine to maintain functionality on OSX.
Sometimes that means going on these wild goose chases, and finding a
work-around but not a solution. Given the time-constraints in my
life, I’m OK with that. - MLD

Someone please give me suggestion regarding my iTunes issue which happened in my macOS last night. I was listening songs on my iTunes, then I got iTunes sync error 54 on it, becaus of that the music stops. Can anybody please help me to fix that?
