Hello, During the installation of GNUradio on Mac OSx 10.11.6(El Capitan) the error down below occurred and aborted the installation. I'm using: macOs 10.11.6, macports v 2.6.,4, xcode 8.2, GNUradio port Version 3.8.3.0

I searched the internet and macports tickets repository for a solution and and found none. I'm attaching the log file mentioned in the console text. Please kindly give me a hand to solve this problem, I'm a newbie on Linux and macports and have no idea on how to proceed. Thanks in advance and best regards, Abraham

Have you installed XCode command line and XCode? ​https://guide.macports.org/#installing.xcode

Then check with xcrun --sdk macosx10.11 --show-sdk-path

[XE3ADC (Abraham Diaz de Leon)]

Thanks for the response: I had Xcode 8 that do not support Xcode command line kit, therefore I managed to install Xcode 8.2 (that does support Xcode command line kit) and the corresponding Xcode line command package. Xcode was placed in the applications folder and the Xcode command line package was installed in the installer's default place. Executing xcrun --sdk macosx10.11 --show-sdk-path gives the following errors:

Abraham-Diaz-de-Leon-Camous-iMac:~ abrahams$ xcrun --sdk macosx10.11 --show-sdk-path
xcodebuild: error: SDK "macosx10.11" cannot be located.
xcodebuild: error: SDK "macosx10.11" cannot be located.
xcrun: error: unable to lookup item 'Path' in SDK 'macosx10.11'

Executing xcrun --show-sdk-path gives the following path:

Abraham-Diaz-de-Leon-Camous-iMac:~ abrahams$ xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk
Abraham-Diaz-de-Leon-Camous-iMac:~ abrahams$

It appears that the Command line package that was in fact installed is MacOSX10.12.sdk Executing xcrun --sdk macosx10.12 --show-sdk-path gives:

Abraham-Diaz-de-Leon-Camous-iMac:~ abrahams$ xcrun --sdk macosx10.**12** --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk
Abraham-Diaz-de-Leon-Camous-iMac:~ abrahams$

How do I procedd?, should I continue with the port install? Many Thanks, Abraham

[ra1nb0w]

give a try with the port.

[XE3ADC (Abraham Diaz de Leon)]

port installation log for second try.

[XE3ADC (Abraham Diaz de Leon)]

HI, I tryed to continue the port installation and obtained same results. I attached the installation log for the second try. Thanks and regards, Abraham

[ra1nb0w]

have you tried sudo port clean py37-pyqt5 && sudo port install py37-pyqt5?

[XE3ADC (Abraham Diaz de Leon)]

No, but i tried with same results at first...

Afterwards, I managed to have port py37-pyqt5 installed succesfuly by doing the following:

1-uninstalled all xcode versions

2-uninstalled all command line package installations

3-installed xcode 8.2.1 and its corresponding command line package(from apple developers site)

4-found out that the command line package was installed in the folloging paths:

a) /library/developers/SDKs/, and

b)/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/

5-both directories contained a directory named MacOSX.sdk and a symlink for it named MacOSX10.12.sdk

6-as the port install looks for the directory MacOSX10.11 and fails because its not found i went on and created with Finder, in both directories, an alias for MacOSX called MacOSX10.11

7-ran the port install py37-pyqt5 again obtaining a succesfull install for py37-pyqt5.

As for the gnuradio port install, now having py37-pyqt5 correctly installed, I resumed the port install gnuradio that eventualy ended sucessfully.

Executed gnuradio-companion and seems to be working properly.

Thanks a ton for your guidance, let me know if I can help with further information.

Best regards, Abraham

Ok. I am not an xcode/SDK expert but reading the SDK 11.x is provided by Xcode 7.3.

I need to catch someone that explain me this :)

[jmroot (Joshua Root)]

If you have the Command Line Tools installed correctly, no SDK will be used on 10.11. The headers in /usr/include and the libraries in /usr/lib will be used.

[XE3ADC (Abraham Diaz de Leon)]

If i had managed to install pyqt5 using other method like pip3, would the gnuradio port install have succeded upon resuming?

[ra1nb0w]

thank you @jmroot for the clarification.

@XE3ADC: no
