Successfully, I uninstalled flac and rebuilt flac-bindings. Unfortunately, this is an production env bug that can only be corrected in the next version, thx bro

Hello! I think you should rebuild flac-bindings with npm rebuild flac-bindings. In latest libflac version (1.4) they changed the number of the shared library:

(see https://xiph.org/flac/changelog.html)

Hope with the recompile is enough to have it working again :)

Lore: This is a common practice in the C/C++ libraries, to have a "binary version" in the name of the shared library. If between versions the API compatibility is broken, the number is incremented.

I delete /node_module/flac_bindings/build folder, and use npm rebuild flac-bindings to re-generate build folder. But I didn't find any node files in build/Release, so I used the make command to try to compile, but he reported a mistake

ps. I also wrote a prebuild script because I couldn't compile it before, and placed the node file from github in the built/release folder so that I could use it.

Mmm I see. I've been looking for the commit I made to make the library work with libflac 1.4 and just in the place where it failed, there is a breaking change (f52cc88). I see here two options:

1. Somehow downgrade your installation of libflac to any of the 1.3 versions
2. Remove your installation of libflac and let my package download the code of a known working version for you (it will take more time to compile but it should work).

Note that I do not have experience with M1/M2 Macs so there is maybe any other issue I didn't know. Let me know if something else does not work.

I would recommend you the second option because it will bundle libflac with your app, so you won't need to copy the library manually for distribution.

You mean, I need uninstall flac in my computer environment variable?

[melchor629]

If you don't have a way to install flac 1.3, then try uninstalling flac installed on your computer. At least temporarily, just to see if compiles fine.

The build script tries to use already installed flac before trying to download and compile flac (because it is faster to use something already compiled). But in this case it seems that is causing you trouble :/
