add linux support?

[phildong]

In theory it should be fairly straight-forward to build on linux. In fact there already seem to be some success! (#32).
So just want to put this issue here to track collective effort to make the DAQ software work on linux, and potentially have official support for linux.

Specifically it would be nice to have:

• documentation and example .pro files to help building from source on linux.
• linux binaries included in future releases.

Related questions: the latest Ubuntu reposistory qt libraries are 5.15.3 (at least in my 22.04 aarm64 image). Does anyone know whether the SW will compile with that version of QT creator?

Similar question regarding OpenCV. Any sense for what version is needed?

OK.. so here is a fork that works on Linux.

Thanks! I have gotten it to build, but I find that I'm getting errors when connecting to webcam or miniscope. Any hints about needed packages (maybe gstreamer ones??)

Can you post what errors you are getting?

Thanks so much for your fork. Compiling was failing at the very end where it was copying files:

cp -f -R "/home/ckemere/Miniscope/Miniscope-DAQ-QT-Software/source/../deviceConfigs" "/home/ckemere/Miniscope/Miniscope-DAQ-QT-Software/source/release/deviceConfigs"
cp: cannot create directory '/home/ckemere/Miniscope/Miniscope-DAQ-QT-Software/source/release/deviceConfigs': No such file or directory
make: *** [Makefile:512: copydata] Error 1

And I ignored it. BUT, it turns out that this meant that videoDevices.json file didn't load and failed silently!

    file.setFileName("deviceConfigs/videoDevices.json");
    bool status = file.open(QIODevice::ReadOnly | QIODevice::Text);
    if (status == true) {
        jsonFile = file.readAll();

I need to make a patch to add some error handling there!
