libiio fails to build under MacOS 10.14.6

[mcquiggi (Kevin McQuiggin)]

Hi There:

I'm a longtime user of MacPorts, thanks to all you folks for creating this service and keeping the thousands of ports running!

I am a gnuradio user and am trying to install libiio and gr-iio on my system, which runs MacOS 10.14.6.

When I "port install libiio" I get the following messages and the port fails to install. It seems to build, but then fails due a problem with /opt/local/lib/python3.7:

I have /opt/local/lib/python3.8, but indeed there is no /opt/local/lib/python3.7.

This seems to be a problem with the install script looking for Python 3.7 but not seeing it as I have Python 3.8.

Any help appreciated. Just wanted to let you know that the install portion of the port is broken.

Please attached the build log as noted toward the END portion of the noted text. I'm guessing this is a duplicate of #60669 ... just a guess without the build log!

[mcquiggi (Kevin McQuiggin)]

Hi Michael:

The build/install log has now been attached to this ticket!

Thanks in advance,

Kevin

Looks like you have an alternative iio install as /Library/Frameworks/iio.framework/iio. Do you know how this got there? As it's in a macOS-standard search path (/Library/Frameworks/), CMake is finding it. If you don't need it, I'd recommend getting rid of it. Then you'll need to do:

sudo port clean libiio

before trying to install it again.

Latest main.log, after removing the errant libiio framework from /Library/Frameworks

[mcquiggi (Kevin McQuiggin)]

Hi Michael:

A bit of narrative to accompany my update - I removed the errant framework and tried to clean/build again. Same error. So I verified that the framework had been removed (dragged to Trash), rebooted the Mac, did another clean and build, with the same result.

Perhaps there is some "deinstall" process necessry to remove the framework or something; my Mac OS management skills are not great.

The old framework was left over from an attempt to install a package directly from Analog Devices without success. I installed it and tried it; no go, so I moved on to the MacPorts version of libiio. I just forgot to remove the leftovers from the failed direct install.

Sorry that this isn't "simple"!

Progress! The errant framework is no longer being found! Now, you need to do the following:

sudo port clean libiio
sudo port selfupdate

then, try installing libiio & this time it should work. I fixed this latest issue less than 24 hours ago :)

Hi Michael:

Success!

Thanks very much.

Great. You're welcome & thanks for reporting back!
