Which version of direwolf is this?
Try using the "dev" branch.

@wb2osz sorry I forgot to mention this, I am already on dev branch, head commit d11bd6f

[meltdown03]

I changed this line to a #warning instead of an error and rebuilt it.

direwolf/src/dwgpsd.c

Line 64 in 7d3c1d1

#error libgps API version might be incompatible.

@meltdown03 does the build work properly? No breaking changes in gpsd?

[wb2osz]

Sometimes a major API number change includes incompatibilities with previous versions.
It might compile successfully but not operate properly without additional source code changes.
You will find conditional compilation, in several places, dealing with those incompatible API changes.
Did you test for correct operation?

[meltdown03]

No, I didn't have a chance to test it yet.

There's a comment on Arch Linux AUR that confirms no regression with new gpsd versions https://aur.archlinux.org/packages/direwolf-git#comment-872500

[wb2osz]

This has been tested on gpsd versions up through 3.25. Closing.
