Unable to compile on macos bigsur

[coding-bunny]

Hello,

I'm unable to get the client to compile under macos bigsur.
I have the Oracle Instant Client v12 installed as we use this for other projects well, but one legacy project seems to have issues installing this properly.

The project originally uses ruby-oci8 2.1.5 on Ruby 1.9.3 (Old I Know)

When not setting any ENV vars, this is what happens:

Fetching ruby-oci8 2.1.5
Installing ruby-oci8 2.1.5 with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /Users/olivar/.rbenv/versions/1.9.3-p551/bin/ruby extconf.rb --with-instant-client=/usr/local/opt/oracle-instant-client

  '--with-instant-client' is an obsolete option. ignore it.

Gem files will remain installed in /Users/olivar/.rbenv/versions/1.9.3-p551/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5 for inspection.
Results logged to /Users/olivar/.rbenv/versions/1.9.3-p551/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5/ext/oci8/gem_make.out

An error occurred while installing ruby-oci8 (2.1.5), and Bundler cannot continue.
Make sure that `gem install ruby-oci8 -v '2.1.5' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  oracle_query was resolved to 0.1.6, which depends on
    ruby-oci8

• Setting the DYLD_LIBRARY_PATH to the lib folder of the client doesn't do anything
• Setting the OCI_DIR doesn't seem to help either
• Upgrading the gem produces the same errors
• Setting the --with-instant-client doens't solve the problem either.

Not sure if this is a client problem or a macos Big Sur issue.

Is it Intel Mac? Otherwise, M1 Mac?

How did you install instant client?
It is installed at /usr/local/opt/oracle-instant-client?
Let me know file names in the directory by ls -l /usr/local/opt/oracle-instant-client?

[coding-bunny]

This is an Intel Mac.
The client is installed with Homebrew, we have our custom tap, but the principle is exactly the same as described in the documentation for homebrew, we just have the files hosted ourselves.

brew --prefix oracle-instant-client
/usr/local/opt/oracle-instant-client

ls -l /usr/local/opt/oracle-instant-client
lrwxr-xr-x  1 olivar  admin  42 Jan 18 10:29 /usr/local/opt/oracle-instant-client -> ../Cellar/oracle-instant-client/12.2.0.1.0

[kubo]

Instant client 12.2.0.1.0 is too old. It doesn't run on Big Sur.

Could you use instant client 19.8?

I'll have to run this through our teams as this will have a major impact.
