MacPorts believes something in the dependency chain of gqrx requires gnuradio to be installed universal. It's not installed universal on your system, so MacPorts is trying to rebuild it universal. To do that, it has to first rebuild gnuradio's dependencies universal. One of gnuradio's dependencies is py27-scipy, and it does not have a universal variant (#19397), so it cannot be built universal, so the operation fails.

I don't yet know why MacPorts believes the universal variant is required here. Typically that happens on 64-bit systems when one of the ports declares that it requires a 32-bit build using the line supported_archs i386 ppc but I don't see that line in gqrx or any of the ports it depends on.

[michaelld (Michael Dickens)]

Can you attach the whole output of "port installed"?

Also, can you try doing (watch the use of backquotes "`", -not- regular single quotes "'"):

sudo port clean `/bin/ls /opt/local/var/macports/build/* | grep -v /opt/local`
sudo port selfupdate

and then try installing gnuradio again. If that fails in a similar fashion then we'll try other things.

woof. Installing gnuradio again is causing trouble.

Try this:

sudo port clean gnuradio
sudo port install gnuradio

I guess this brings us back to Ryan's observation about the absent universal variant of py27-scipy.

[michaelld (Michael Dickens)]

OK; how about this:

1. make sure that py27-numpy and py27-scipy are installed -without- +universal;
2. Do:

   sudo port clean gnuradio
   sudo port install gnuradio -universal

Any word on this issue? Has it been resolved one way or the other?

Hi Michael,

I'm also trying to install gqrx (OS X 10.5.8/PowerPC) and py27-scipy is failing. I did try the suggested above (sudo port clean gnuradio/sudo port install gnuradio -universal), however that didn't help. I've attached the log to the ticket.

Let me know if anything else might be helpful.

[iibov@…]

OK; well, first off PowerPC is not longer officially supported. Nor is 10.5.8. You might be able to get GNU Radio installed and working; maybe not too; no promises!

The issue here is that py27-scipy +gfortran uses the new gcc5 for Fortran, and this does not seem to recognize that the host computer is a PowerPC; it is trying to build as x86_64 for some reason. Here's my recommendation:

sudo port clean py27-scipy
sudo port install py27-scipy +gcc47

Try using an older compiler that might provided better support for PowerPC. I've no idea if the above will work, but it's worth a try. It might be that the new SciPy just does not work with PowerPC systems; they are pretty old, after all -- nothing personal, just being real here.

[iibov@…]

Yeah, it's an old machine but I wanted to see if I can make use of it for my FCD+ and since this is the first time I'm using MacPorts I wasn't sure if gqrx is supported for it.

So anyway, I did try your suggestion (port clean/port install py27-scipy +gcc47) and here is the outcome after several hours of waiting:

[michaelld (Michael Dickens)]

Same result: trying to build as x86_64. My only thoughts for advice is for you to try an older version of SciPy. There's a guide for how to do this here: ​https://trac.macports.org/wiki/howto/InstallingOlderPort . I'd tend to believe that going back to 0.15.1 first & testing it; if it fails, try 0.14.1; then 0.13.3. I'd guess that if you get far enough back one of those will work. It'll be quite a bit of work on your end, but I think those older versions will still work with GNU Radio and Gqrx.

[iibov@…]

Alright Michael, I did the following:

1. sudo port clean py27-scipy
2. svn checkout -r 131492 https://svn.macports.org/repository/macports/trunk/dports/python/py-scipy/
3. cd py-scipy
4. sudo port install

I noticed it was trying to fetch 0.16.0... Am I doing something wrong or is it really trying to install 0.16.0 even though I've specified 0.15.0?

[iibov@…]

py27-scipy-log-0.15.0

[michaelld (Michael Dickens)]

You can find the revision log for this Portfile at ​https://trac.macports.org/log/trunk/dports/python/py-scipy/Portfile .

I think that when you do the "sudo port install" without a portname for py*-scipy, you'll get "py-scipy" which then becomes py27-scipy. But, the py27-scipy will be the one from within MacPorts, not the one from the current Portfile. The only way I know of to do what you want is to replace the Portfile for py-scipy with the one you want to use. In this manner you'll always get the correct version of py27-scipy. As you found out, you got 0.16.0, not 0.15.0. You can test this via "port info" on the local Portfile (with or without a name).

Keep hacking!

[iibov@…]

Yeah, I see when I cat /py-scipy/Portfile
[...]
name py-scipy
version 0.15.0

I wanted to test whether anything else needs to be specified after sudo port install once in the local directory where Portfile is and I did the following:

[michaelld (Michael Dickens)]

Right. Installing prior versions only works with the default port. Since airspy is the only port provided, it is the default & hence works with this way of doing things. For Python ports, py-FOO is the default port, but it doesn't actually exist; it just redirects to some pyXY-FOO port, typically py27 still I think. And, that port will NOT come from the current Portfile unless you're in the main dports repo. Thus, the best way to do what you want is to just overwrite the current py-scipy Portfile with the older one & give it a try. Worst case is it won't work and you can always re-sync to the current Portfile.

[iibov@…]

I started by trying to install a really old version of py-scipy. What can be seen from the log is that there was no need to replace the Portfile (presumably because it's not a py27 version?!), it worked from issuing the install command from the current directory. Anyway, installing 0.7.0 didn't work: ​http://pastebin.com/s8JgVgrv

Later on I tried my luck with 0.15.0 and this time I did indeed replace Portfile at /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python/py-scipy/ That didn't work either: ​http://pastebin.com/zGc0L9xJ

Last thing I attempted was installing 0.13.3 and the failure was identical to 0.15.0

Is there anything else I can possibly do?!

[iibov@…]

scipy0701

[iibov@…]

scipy0.15.0

[michaelld (Michael Dickens)]

OK; my bad. You need to replace the whole directory, not just the Portfile; so, do the svn co then cd into that directory and move all of those files into place; clean py27-scipy and try again. I would think that just going back to 0.14 or 0.13 would be good enough while still providing the modern capabilities needed by GNU Radio (etc).

[iibov@…]

The instructions at ​http://www.scipy.org/install.html are

sudo port install py27-numpy py27-scipy py27-matplotlib py27-ipython +notebook py27-pandas py27-sympy py27-nose

I installed everything except py27-pandas since one of its dependencies is py27-scipy itself. So far it seems myriad of other ports work but not py27-scipy :/

Hi,

I tried as instructed but again it didn't work.

main-py-scipy0.13

[michaelld (Michael Dickens)]

OK; looks like you've got the correct SciPy version now. Let me give this a go on my home PPC 10.5 box & see what happens. I'm guessing that SciPy itself is messing up the build internally.

[michaelld (Michael Dickens)]

On my PPC box, I can install py27-scipy as either "py27-scipy @0.17.0_0+gfortran" or "py27-scipy @0.17.0_0+gcc5". Both pass all expected tests. I'm wondering how you're trying to install py27-scipy (the exact command you're issuing to install py27-scipy), and also what's already installed on your PPC setup ("port installed and active").

Replying to michaelld@…:

When I tried to install the old versions of py27-scipy I would cd to the directory where I'd downloaded the files and then issue sudo port install, there is output in reply № 18 above, otherwise I'd type, for example, sudo port install gqrx (gqrx is what I've been trying to install all along and what lead me to MacPorts in first place).

Now, I have some good news: py27-scipy @0.17.0_0+gfortran installed successfully when I tried once again to install gqrx, I guess I really shouldn't have picked up from where I left it a while ago i.e. trying to install an older version of py27-scpipy. I really have no explanation why 0.17 worked for me unlike every other version. Apologies for wasting your time.

However, grqx still won't install because of the following: it still needs gnuradio uhd gr-osmosdr gr-fcdproplus.

gr-osmosdr and gr-fcdproplus report that they cannot build doxygen which I already have: doxygen @1.8.9.1_0; QUESTION: is there a way to make them use the already installed version? I looked at the doxygen tickets and I see others too have problem with it and I've no idea when that's going to be fixed.

I'll upload the logs from:

sudo port install gqrx
sudo port install gnuradio
sudo port install uhd
sudo port install gr-osmosdr 
sudo port install gr-fcdproplus

(each of these failed installs is followed by a clean command, namely: sudo port install gqrx -> sudo clean gqrx -> sudo port install gnuradio etc)

and what I have currently installed so you can get the full picture. Terminal output: ​http://pastebin.com/eLZ9pPdj
