Subject: [PATCH] ext/openssl/extconf.rb: require OpenSSL version >= 1.0.1, < 3
|
|
|
6daba0 |
|
|
|
6daba0 |
Ruby/OpenSSL 2.1.x and 2.2.x will not support OpenSSL 3.0 API. Let's
|
|
|
6daba0 |
make extconf.rb explicitly check the version number to be within the
|
|
|
6daba0 |
acceptable range, since it will not compile anyway.
|
|
