在 OSX 上构建 mariadb-connector-c

Question

我正在尝试在最新的 OSX 上构建 C connector for MariaDB，但它似乎因与 SSL 相关的错误而失败。我使用 Macports (/opt/local/lib/openssl) 安装了 SSL，并添加了一个指向它的包含：

find_package(OpenSSL REQUIRED)
target_include_directories(tests PRIVATE ${OPENSSL_INCLUDE_DIR})

但是构建它returns同样的错误：

Answer 1

MariaDB Connector/C 可与所有受支持的 OpenSSL 版本一起正常工作。

错误 'Undefined symbols for architecture x86_64 "_X509_check_host"' 表示您使用的是不再受支持的旧 OpenSSL 版本。 X509_check_host 是在 OpenSSL 1.0.2 中引入的。

请将您的 OpenSSL 版本更新到 1.0.2 或更高版本。另见 https://www.openssl.org/policies/releasestrat.html

Answer 2

出于某种原因，基本上 CMake 使用 Macports 头文件而不是系统库。
