Mac OS 上未定义的体系结构符号 x86_64

Question

我正在尝试在 Mac OS 10.10 上安装 Stunnel 软件，但出现以下错误

Undefined symbols for architecture x86_64

正在从终端执行 make 命令。

详细日志如下：

Answer 1

您需要使用 pthread 和 pie 将参数传递给 link 不是 -pthread，而是 -lpthread，不是 -pie，而是 -lpie

/usr/local/openssl/ 中也没有库，请尝试使用 brew 或 macports 安装它们，或者只下载二进制文件。

提示就在眼前：

clang: warning: argument unused during compilation: '-pthread'

...

ld: warning: directory not found for option '-L/usr/local/openssl/lib64'

Answer 2

出现此问题是因为 installable 依赖于 OpenSSL，并且无法找到与 OpenSSL 相关的库。

这个问题可能有两个原因- 1、系统中没有安装OpenSSL。在这种情况下，需要先安装OpenSSL，然后再安装stunnel。

OpenSSL 未安装在标准路径中。
