使用 --enable-ssl 编译失败，但如果未指定则可以工作

Question

我正在编译旧版本的 Squid，版本 2.6。我需要使用 ssl 支持来编译它，因此我从源代码编译/安装了 openssl 版本 1.0.2n。我把它安装在/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 解决了这个问题:)

您有 dll 函数的未解析引用，您的构建需要包含 -ldl 来解析它们

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=/usr/local/ssl LDFLAGS= 进行编译“-低密度脂蛋白”
