Hello all,
I tried to compile the freedv 1.9.3 with Linux Mint 19.3 and get the following error:
With the last 10 official versions I had no problem to compile it.

Looks like Mint 19.3 is no longer a supported release, are you in a position to try a newer Mint LTS release? From what I see the earliest LTS release is Mint 20.x which is supported until April 2025, but Mint 21.x is supported until April 2027.

I'm thinking this could be a library versioning issue, requiring something not available in Mint 19.x any more.

[vwpolo16]

Hi Tyrbiter,
a newer Mint version is not an option. I have 2 SDR radios where the SDR software is not running on a newer Mint version. I tried this already but I have to stay at Mint 19.3 or older.
So I think I have to live with Freedv 1.9.1 which I currently use.

On Mint 21.2 (19.3 doesn't seem to be available for download anymore), I can't seem to duplicate that error:

That said, does #578 help at all? I made some changes based on the errors you provided.

I see, that does make it difficult. Maybe @tmiw has fixed this now, please comment so we know.

I was able to find a 19.3 ISO but it looks like Codec2 needs CMake 3.13, which that version doesn't have. What version of Codec2 are you using, @vwpolo16?

[tmiw]

I was able to use snap to download a newer CMake and finish resolving the remaining compiler errors. Those changes are now in master and will be in the next FreeDV release. Let me know if you run into any additional issues.

BTW it looks like PulseAudio support wasn't building, either, so you should also be able to use that now instead of PortAudio.

[vwpolo16]

Hello tmiw,
the new version 1.9.4 works on Mint 19.3.
I can compile now both versions (port audio and pulseaudio) with Mint 19.3 and they are working on my computer. Pulseaudio now works the first time.
Thank you very much for providing this fix.
