如何在Emacs中更改构建/调试的工作目录？

Question

I'm trying to get accustomed to using Emacs for building and debugging, although I'm having some difficulties. My biggest problem right now is that I need to be in (eg have a file open in) the root directory to make -k my applications and I need to be in the binaries directory to run gdb MyApp .

Is it futile to try to get Ctrl+Shift+B to make -k -C <my_hard_coded_dir> and some type of ditto with F5 running gdb <MyApp> from my bin directory? Never mind if the shift key is to much of a hassle for Emacs.

Answer 1

To specify what Mx make uses for compilation, you specify the compile-command variable.

(setq compile-command "make -c /path/to/makefile")

For your GDB stuff, the variable is gud-gdb-command-name, so

(setq gud-gdb-command-name "gdb --anotate=3 -cd /path/to/exec")

Answer 2

for compiling i use this spippet in my .emacs

(global-set-key [f2]   'compile)
(global-set-key [f3]   'next-error)
(setq compile-command "u: & cd \\gbceinspielen\\trunk\\src\\compile & make -k ")

the command "gdb" starts the debugger, but i do not know, wether there is an equivalent to compile-command.

I'm personaly use EDE to keep compilation settings for concrete projects, and create compile command on the fly. You can see how it works in my cedet config , starting with line 100
