Macos Mac OS上架构x86_64的未定义符号

我正试图在Mac OS 10.10上安装stunnel软件，但出现以下错误

从终端执行

make

命令时

您需要传递参数以链接pthread和pie 不是

-pthread

而是

-lpthread

不是

-pie

而是

-lpie

另外，

/usr/local/openssl/

中没有lib，请尝试使用brew或macports安装它们，或者下载二进制文件

提示就在眼前：

叮当声：警告：编译期间未使用参数：'-pthread'

ld:警告：找不到选项'-L/usr/local/openssl/lib64'的目录

---

这个问题是因为installable依赖于OpenSSL，并且它无法找到与OpenSSL相关的库

这个问题可能有两个原因- 1.系统中未安装OpenSSL。在这种情况下，在安装stunnel之前，需要先安装OpenSSL

OpenSSL未安装在标准路径中

---

brew安装stunnel

完成（）。Linker表示找不到x86_64体系结构的符号。另外，如果您仔细阅读日志（

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

），它还表示找不到openssl目录（32位和64位）。同时安装openssl并尝试再次构建它。或者只需安装自制软件和

brew安装stunnel

。
