Serialplot build fails

[gbThreepwood]

I have successfully used serialplot in the past, but today when I needed to use it for some measurements, I got the error serialplot: symbol lookup error: serialplot: undefined symbol: _ZN13QwtPlotZoomer7setAxisEii when I tried to start it

Figured I had to update the software, but I am also having trouble building it.

Not sure if this issue is isolated to my specific system configuration, or if it is something everyone will face if they update their system. I am running Manjaro with the latest updates, and tried building through AUR, as well as manually.

Some relevant packages and their version number:
qwt 6.2.0-1
qt5-serialport 5.15.2-1
qt5-base 5.15.2+kde+r263-1

This is probably related to the Qwt 6.2. If you compile from the source and let the cmake download and build the Qwt (which is set as version 6.1 at the moment), it should work.

[gbThreepwood]

Yes, that worked. Thanks.
