Webp not working on M1 Mac (Apple Silicon)

[corygrunk]

I installed Pixlet via Homebrew on a M1 MacBook Pro, but am getting the following errors with the Web library when running the "Hello World" curl command:

Library not loaded: /usr/local/opt/webp/lib/libwebpdemux.2.dylib
  Referenced from: /opt/homebrew/bin/pixlet
  Reason: no suitable image found.  Did find:
	/usr/local/opt/webp/lib/libwebpdemux.2.dylib: mach-o, but wrong architecture
	/usr/local/opt/webp/lib/libwebpdemux.2.dylib: stat() failed with errno=1
	/usr/local/opt/webp/lib/libwebpdemux.2.dylib: mach-o, but wrong architecture

Hey @corygrunk! So sorry for the delay. None of us at Tidbyt have access to an M1 Mac, so we'd certainly need help from the community to be able to support M1 based installs at the moment. Can you confirm if this is still an issue?

Actually, it is more of an issue now. I revisited this today and am unable to install Pixlet through brew on an M1 Mac. I run the install command in Homebrew and get this error:

Error: Invalid formula: /opt/homebrew/Library/Taps/tidbyt/homebrew-tidbyt/pixlet.rb formulae require at least a URL
Error: Cannot tap tidbyt/tidbyt: invalid syntax in tap!

@corygrunk I was able to install on my M1 but had to build from source. Here are the steps I did:

Pixlet Installation on Apple Silicon with Homebrew

1. Install Golang and WebP via Homebrew

    brew install go
    brew install webp
   

2. Add webp to .zshrc / .bashrc:

    export CPATH=/opt/homebrew/include
    export LIBRARY_PATH=/opt/homebrew/lib
   

3. Follow Pixlet build steps

4. Add pixlet to .zshrc / .bashrc:

    export PATH=/PATH/TO/pixlet:$PATH

Can confirm I got the original error on an M1 Mac:

Error: Invalid formula: /opt/homebrew/Library/Taps/tidbyt/homebrew-tidbyt/pixlet.rb formulae require at least a URL
Error: Cannot tap tidbyt/tidbyt: invalid syntax in tap!

but I was also able to build it from source with @btjones instructions and start pixlet.

Hi folks! I'm going to close this in favor of #38. @btjones's solution works in the immediate term (thanks @btjones!!) and we're aiming get #38 closed in the next few days.
