Error building 2.2.2 in 64-bit

[RandomTroll]

I switched to 64-bit (Slackware 14.2, updated daily, kernel 4.17.1, self-built). I downloaded the latest Audacity (2.2.2-rc1) When I build I get:

Is this a wxWidgets problem? I can't build it either.

Are you saying that you don't have a working version of WxWidgets?

[RandomTroll]

I had a working version of wxWidgets. It seemed to be the current version the first place I looked. I downloaded the source anew but still couldn't build. More searching turned up version 3.04 which I could build, then I could build Audacity. Apologize for my bungling.
