brotli/port.h error in Erlang/OTP 26

[stefholbrook]

Hi! I'm running into an issue that I'm hoping you can help me with. It looks like brotli doesn't compile when using OTP 26. I was running 25 locally where everything ran fine, and saw the error in our CI where we're running OTP 26. I was then able to reproduce the error locally when switching to Erlang version 26.0.2. Thanks in advance!

Steps to reproduce:

1. Switch to latest Erlang asdf local erlang 26.0.2
2. rm -rf _build deps
3. mix do deps.get, deps.compile

Error:

I'm looking into the issue.

@stefholbrook Could you confirm if the issue is fixed with v0.3.2?

@yjh0502 It worked! I was initially getting an error, but just had to unset LDFLAGS. Thank you!!
