I’ve just hit a few snags using the build instructions related to out of date conan references and SSL certificates. In a nutshell I had to:-
use pip to uninstall and then reinstall conan to get the latest version
use conan remote to remove and then add both conancenter and conan-center both of these pointing to https://center.conan.io rather than previous targets.
I seem to be having this or a similar problem. Tried to do the suggested solutions, but I’m still getting errors. Perhaps not the same, or perhaps I didn’t know how to solve the problems. Any help would be appreciated. Here is the cmake output:
ERROR: wxwidgets/126.96.36.199-audacity: Error in source() method, line 168
PermissionError: [WinError 5] Access is denied: ‘wxWidgets-188.8.131.52-audacity’ → ‘source_subfolder’
Disabling the anti-virus or adding an exception for C:\Users<YourUserName>.conan is a temporary workaround. It’s usually the AV that causes rename races, but not the only source, the Windows search indexer can also cause these etc. There’s a special trick to avoid these races, IIRC, which robocopy is using. (I don’t remember the details, but it’s probably discussed in https://youtu.be/uhRWMGBjlO8?t=506)
I’m like 75% sure the problem is that some other process (like the AV) opens a file in that tree without FILE_SHARE_DELETE. https://youtu.be/uhRWMGBjlO8?t=818 Since conan downloads large zip packages with binaries in them, the AV will take a while to finish scanning them, and os.rename will fail in the meantime. Worth noting that I’m not building on the C: drive, which makes some tricks like moving files to %TEMP% fail, because they are non-atomic if you build on a different drive.
Although the cmake managed to build a whole lot after that (I turned off the AV), it still failed for me gain with a different kind of error…

This one is different in nature from the os.rename one, looks like some kind of permission problem. I guess I’ll take the invitation to discord for this.
Well, I found the root cause of that myself https://github.com/audacity/audacity/issues/2431 Basically you have to use the x86_64 cross-compiler for now, using the native x64 compiler will fail to compile libmp3lame, at least, and possibly other parts.
