如何调整Emacs的编译错误从编译缓冲区获取的路径？ [英] How to adjust the path that Emacs' compile-goto-error gets from the compilation buffer?

问题描述

我正在使用Emacs 23，并且存在以下问题：

I am using Emacs 23 and have the following problem:

我从Emacs内部运行项目的构建系统，例如Mx compile-> cd / foo / bar& & ./build

I run our project's build system from within Emacs like M-x compile -> cd /foo/bar && ./build

构建系统现在执行了一些魔术操作，将 cd放入构建过程的某个子目录中，然后gcc抛出错误：

The build system now does some magic, "cd"s into some subdirectory for the build process and then gcc throws an error:

../ src / somesource.cc：50错误：blablabla

../src/somesource.cc:50 error: blablabla

现在问题是Emacs找不到该路径，因为它假定编译过程始于/ foo / bar，而不是始于/ foo / bar / builddir。因此，开头的 ../不适用于Emacs，例如运行编译转到错误时。

Now the problem is that Emacs won't find that path, because it assumes the compile process started out in /foo/bar, and not in /foo/bar/builddir. So the leading "../" is not working for Emacs, e.g. when running compile-goto-error. Is there a way to tell Emacs to try skipping leading "../"?

推荐答案

最好的方法可能是更改Emacs尝试跳过开头的 ../吗？构建系统以在更改目录时发出消息。 Emacs寻找

The best solution might be to change the build system to emit messages when it changes directories. Emacs looks for

Entering directory `...'
... 
Leaving directory `...'

（请参阅编译目录匹配器变量。如果构建系统在更改目录时确实发出了消息，但它们不是Emacs所寻找的格式，则可以将新的正则表达式添加到 compilation-directory-matcher 。）

(See the compilation-directory-matcher variable. If your build system does emit messages when it changes directories, but they're not in the format Emacs is looking for, you can add new regexps to compilation-directory-matcher.)

另一种解决方案是更改 compilation-search-path （这是目录）。

The other solution is to change compilation-search-path (which is a list of directories).
