Problems on Mac OS X 10.12

The solution in this case was to open /etc/hosts in a text editor and comment out the line

127.0.0.1 localhost

Is this a general problem with Mac OS X 10.12?

I don't have this problem. OS X 10.12.2 Gqrx v2.6-73-g80f008f Boost 1.63

And I haven't commented out the specific line in /etc/host.

Hi @mehdideveloper

Thanks for the info! Can you tell me which version of Qt you are using. Thanks.

[mehdideveloper]

Hi @csete Qt 5.6.1

[csete]

Thanks.

Hi,

FreeBSD has a similar issue. rtl_tcp binds to 127.0.0.1 ; gqrx tries 'localhost' and just keeps looping over on the IPv6 localhost address, getting ECONNREFUSED each time.

Is it possible to make gqrx actually break out of the connect loop and just throw up a UI failure showing the IP address and port that it failed on?

[erikarn]

In fact my problem is it gets stuck in a connect() loop. I'll open up another ticket.

I encountered this with the latest MacPorts version and fixed it with the update to /etc/hosts, ensuring an inclusion of a localhost line. The QT5 error message indicating to run from a console was not helpful as no other error message was displayed on the console upon program exit.
