在/ usr /斌/劳工处：找不到-lL/usr/lib目录

Question

我现在面临一个奇怪的错误，而试图编译fbthrift（https://github.com/facebook/fbthrift）在Ubuntu 16.04

它为什么不找的/ usr/lib？

Answer 1

生成文件中生成一个链接命令，上面写着：

... -l -L/usr/lib ... 

Makefile中的链接的命令可能会指定为-l$(SOMEVARIABLE)，在此处，将变量未设置出于某种原因，所以它得到扩大一个空的字符串。

因此，这被解释为与名为“-L/usr/lib”的共享库链接的指令，当然这完全是假的。

不幸的是，没有可以推送的万能魔法按钮，并修复了这个错误。有必要调查这个软件包的配置和/或构建过程中发生了什么，并对其进行修复。
