Audacity can't find "libwx_gtk2u_xrc-3.1.so.1" on Oracle Linux

[steve]

now Audacity launches

Excellent

it gives me this error.

When does that appear?
Which version of Audacity did you build?

When does that appear?

It appears when I click the "Record" button.

Which version of Audacity did you build?

I built Audacity 2.3.2. Here is what I see when I click Help>About:

One more problem. Audacity claims it can't find the "libavformat.so.55" file, even when I point it right to it.

Though, none of those are serious problems. I can record the audio using some other app, and I can use ffmpeg through command line, I don't need to use it through Audacity.

Audacity is very fussy about the version of FFmpeg, because, by default, Audacity links to it dynamically.
What works for me is to build against system headers (on Debian based systems this requires installing the "libavutil-dev" package), and then build Audacity with dynamic loading disabled.

Code: Select all

../configure --with-lib-preference="local system" --with-ffmpeg="system" --disable-dynamic-loading

It may be best to ignore this for now while we concentrate on getting Audacity working for you.

Please post the "Audio device info".

1. "Help menu > Diagnostics > Audio device Info"
2. Wait for the info to appear
3. Click the "Save" button and save the info somewhere convenient
4. Attach the saved file to your reply

Here is the "deviceinfo.txt" file.

Perhaps related to that, if I start Audacity from command line, I get the following warnings:

Perhaps related to that, if I start Audacity from command line, I get the following warnings:

Nothing to worry about there. Those messages are "normal".

Here is the "deviceinfo.txt" file.

That's interesting. According to the device info, you don't have any recording devices and you don't have PulseAudio.

What do you get if you enter in a Terminal window:

Code: Select all

arecord -l

(last character is lower case "L")

In the absence of PulseAudio, your sound card probably does not support multiple client applications. Is some other application using the recording device? Why don't you have PulseAudio installed?

I don't even know what is PulseAudio. What I do know is that GNOME Cheese can record audio without problems.
