使用 --enable-ssl 编译失败，但如果未指定则可以运行
Compiling with --enable-ssl fails but works if not specified
我正在编译旧版本的 Squid，2.6 版。我需要使用 ssl 支持来编译它，所以我 compiled/installed 来自源代码的 openssl 版本 1.0.2n。我安装在 /usr/local/ssl
所以我使用./configure -prefix=/opt/squid --with-openssl=/usr/local/ssl编译了Squid。 make 成功。
但是，当我使用./configure -prefix=/opt/squid --with-openssl=/usr/local/ssl --enable-ssl编译它时，遇到了以下错误。

我不确定如何找出问题以及如何解决它。
更新：
我通过使用 --with-dl 弄明白了:)
您有未解析的 dll 函数引用，您的构建需要包含 -ldl 以解析它们
您需要检查您的配置脚本是否支持使用 LDFLAGS 添加新的链接器标志，然后您可以尝试使用 ./configure -prefix=/opt/squid --with-openssl=[=15 进行编译=] LDFLAGS="-ldl"
