我在 ubuntu 16.04 上尝试编译 fbthrift ( https://github.com/facebook/fbthrift ) 时遇到奇怪的错误

为什么找不到/usr/lib ？
最佳答案
makefile 正在生成一个链接命令，内容如下:
... -l -L/usr/lib ...
makefile 中的链接命令可能在此处指定为 -l$(SOMEVARIABLE)，并且由于某种原因未设置该变量，因此它会扩展为空字符串。
因此，这被解释为链接到名称为“-L/usr/lib”的共享库的指令，这当然是完全伪造的。
不幸的是，没有可以按下的通用魔法按钮，请修复此错误。有必要调查此包的配置和/或构建过程中出现的问题并修复它。
关于c++ -/usr/bin/ld : cannot find -l-L/usr/lib，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39349458/
