小编neg*_*ega的帖子

我在Ubuntu16.04上构建了emacs26，执行./config --prefix=/usr/local/emacs后显示如下：

configure: error: The following required libraries were not found:
     gnutls
Maybe some development libraries/packages are missing?
If you don't want to link with them give
     --with-gnutls=no
as options to configure

我试图解决这个问题很多次，但是失败了。谁能帮助我，非常感谢。

最近我开始了一个 C++ 的新项目。问题是，当我尝试编译它时，出现链接错误。我今天花了一整天的时间尝试调试它，但我并没有真正在任何地方找到好的解决方案。如果有人能帮忙那就太好了。我使用的是 Mac Sierra。
