MacPorts for Intel - newbie question

GNU Radio
1

Hi (from a newbie here to Gnu Radio),

Just trying to wet my feet in all this… trying to build the software
on a new Intel Core 2 Duo MacBook with OSX 10.4.9…

Was following the notes from Jon Jacky & Michael D. about OSX
installations…
Started the pre-requisites …
Installed Xcode 2.4.1.
Installed Subversion.
Installed MacPorts as suggested in Jon’s notes from a
DarwinPorts-1.0.dmg but when I went to update it using
sudo port -d selfupdate
I got the message:
Failed to initialize ports system, no suitable image found. Did
find:
/opt/local/share/darwinports/Tcl/pextlib1.0/Pextlib.dylib:
mach-o, but wrong architecture
which even to a limited tech like me suggests it was expecting PPC ?

I also tried the more detailed description in Michael’s document using
the script dp_inst.csh on page 3 but got the same errors, presumably for
the same reason.

Of course without MacPorts working, I am not likely to get much further
with my GR install! Sorry to ask for such basic help but would
appreciate any pointers either on or off list.

Thanks,
Jonathan

(0) “DarwinPorts-1.0.dmg” is for PPC only and OSX 10.2 and 10.3; it
may or not work on an Intel-Mac or on 10.4; it wasn’t designed to
work on an Intel-Mac or 10.4.

(1) The first version that was a universal install (and thus for 10.4
and Intel-Mac) is 1.2.1; start with that or 1.3, or the recently
released 1.4; then “port” should run properly and “sudo port
selfupdate” should also work properly. The “mp_inst.csh” script I
wrote is really meant for 1.2.1+, since there were also grammar
changes in the way “port” works.

If you want to get rid of your original “DarwinPort-1.0” install, and
have nothing else installed, the simplest way is “sudo rm -rf /opt”.
Even if you have something else installed, I would advise you to just
remove everything and start from scratch, since there have been quite
a few changes in “port” over the years and versions.

(2) Don’t start with a pre-compiled install unless you have to;
download the source & compile it in the “usual” manner (./configure;
make; sudo make install). Again, this is all done by the
“mp_inst.csh” script.

If what you want is to get the background libraries / apps / includes
for compiling GNU Radio, the simplest way - barring other constraints

  • is to use the “mp_inst.csh” script … it just “does it all” with
    minimal hassle … be patient, it takes a while to install even on a
    zippy Intel-Mac. - MLD
