Unable to compile

[Joe2k1]

Hello,

I recently upgraded my laptop running unbunto. Unfortunately, I am unable to compile phidgets. I just downloaded the tar to the download folder. I attempted to do the configure, make. It gives the error below during the make process.

I am running 5.15-0.69 generic #76 Ubuntu SMP - March 17 2023.

Edit: Yes, it’s 2.8.2 (f525b16) set to work with Phidgets. Again it worked fine before but after the upgrade. After some additional troubleshooting. It seems that the libphidget22 was not installed. I untarred into the downloads folder. I get an error message during the make process. Here is the error below:

I'd recommend installing from package on Ubuntu. If you're using kinetic or something, you can just use the jammy repo.

I will update the source to handle these warnings.

I was using Linux Mint. I updated using the package install thanks to assistance from the technical support team. I was able to successfully install Phidgets. Many thanks.
