c - 为什么 C 的编译 stderr 包含我正在使用的静态库的开发人员的密码？

Question

我正在尝试使用 liboidc-agent (Github) 这是编译好的静态库。

我认为它编译错误，因为当我尝试编译我的程序并链接库时，请参阅下面的日志。

注意:/home/gabriel/Dokumente/... 不是我的目录。但最有可能是开发人员的目录。它不应该在那里，对吧？库应该是可重复使用的代码包。

如何解决这个问题并使 liboidc-agent 可用？ Minimal example (Github) 只需运行“make”

还是我遗漏了什么？ 谢谢你的帮助!

.a 文件只是一个包含多个捆绑在一起的 .o 文件的存档，以及一个可选的符号索引。并且 .o 文件确实引用了源文件，因此错误更精确 - 否则你只会从 api.o 而不是实际的源文件中得到错误它来自哪里。

真正的问题是整个 liboidc-agent.a 只是垃圾。如果您查看文件列表:

% ar t liboidc-agent.a 
api.o
api.o
api.o
api.o
api.o
api.o
api.o
api.o
api.o
api.o
api.o

它没有多个不同的目标文件，而是具有多个副本的相同文件。与存储库所在的用户唠叨，从另一个地方获取库或自己从源代码构建它。
