Re: [gpsd-users] Problems building gpsd 3.18.1 from source on Ubuntu 18.04 LTS

Yo Rich!

I see many problems.  Looks like you missed some prerequisites mentioned
in build.txt.

If you keep track of what you have to install to make this work, then
I'll try to improve build.txt to make things a bit more obvious.

Output of configure is always worth reading closely.

No ncurses means things like cgps and gpsmon will not be built.

No libusb causes issues with some drivers.

dbus lets gpsd talk to Firefox, etc.

That means you will not get KPPS.  So you PPS accuracy will suffer
a lot.

No man pages.

No Qt lib will be built.

And back to the main problem:

I have no idea where the "-specs=/usr/share/dpkg/no-link.specs" thing
is coming from.  I suspect from some of the missing dependencies
covered above.  Maybe you have not installed the "python-dev" package?
