Fresh Build errors out on SU_SPECTTUNER_CHANNEL_TIME_DOMAIN undeclared

[jlpoolen]

I'm running Gentoo Linux on a Raspberry Pi5. I was able to install SigDigger using Gentoo's portage packaging system, but have had an extremely difficult time getting SigDigger to find my 2 RTL-SDRs connected to the Pi. I've gone back and forth with Gentoo's ebuilds and created my own custom ebuild because I found that there were some version/path issues in the library. My efforts to work within Gentoo's packages did not bear fruit. It looks like the problem is at the soapy level.

So, I decided to try a from-the-wild install of SigDigger and its dependencies and followed your instructions on the SigDigger site:

   % git clone --recursive https://github.com/BatchDrake/sigutils
   % cd sigutils && mkdir -p build && cd build && cmake .. && make && sudo make install && cd ../..
   % git clone --recursive https://github.com/BatchDrake/suscan
   % cd suscan && mkdir -p build && cd build && cmake .. && make && sudo make install && cd ../..
   % git clone https://github.com/BatchDrake/SuWidgets
   % cd SuWidgets && qmake6 SuWidgetsLib.pro && make && sudo make install && cd ..
   % git clone https://github.com/BatchDrake/SigDigger
   % cd SigDigger && qmake6 SigDigger.pro && make && sudo make install && cd ..

I succeeded in building and installing sigutils. I'm getting hung up on suscan. I figure you have been refactoring some of your variables and maybe something has been overlooked that is causing suscan to fail. Here's my attempt:

jlpoole@rpi5 /usr/local/src $ sudo rm -r suscan

I do have the STL_SDRs working and have been using them with other programs; in fact I have dedicated one for a specific frequency, 119.1 MHz, of our local airport tower, and have placed a UDP server on it then a UDP->TCP/IP server under than for programs such as openwebrx+ that cannot connect to a UDP server. I very much would like to see SigDigger work, your "with love" quip in the credits demonstrates an ethos in a developer that should be encouraged and rewarded. So I bring the above to your attention with the hope it will not distract you from getting your 0.4 release out the door.

I figure that at a minimum, suscan should build, especially since it seems to with Gentoo's package:

jlpoole@rpi5 /usr/local/src/suscan/build $ eix suscan

I confirmed tag v0.3.0 builds and see you really do have a lot of files, e.g. 151, as work in progress. I don't expect much action on this Issue as you're still working on this, but I note this for posterity.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Okay this is extremely odd. I will try to reproduce the build myself ASAP. El mié, 7 may 2025, 12:15, John Poole ***@***.***> escribió:
