Management C Project Files with Emacs?

Management C Project Files with Emacs?

[Daniel]

Hi,

If I want to compile a large project like Linux Kernel, I don't know
how I can use emacs.

1. For example, if I modified <linux>/drivers/usb/core/hcd.c with
emacs, then How I can compile linux kernel by M-x compile command?
When I do the command, it is saying that there is no makefile. So, I
use "M-x compile RET make -f /usr/src/linux/makefile", but it
complains that there is no definition of u32 etc. How do I do that?

2. Whenever opening a file, it seems that emacs change current
directory. So, I cannot simply type "M-x compile RET make". Is there
anyway to have emacs to stick on specific directory?

I remember that I was using rpm to build the kernel in shell ... and  
when you rename this buffer (to *kernel* for example), you can create  
a new *shell* buffer.

Thank you for your response, but that does not seem to be not what I
want.

First, the kernel compile is just for example to show for building big
project.
Second, I don't understand how I rename the buffer name, and how
creating a new *shell* buffer would help me out to compile.

What about X11R7.2? Less bleeding edge would be X11R7.1. The latter  
one takes for me a few hours – is this big enough? (Editing the  
build.sh script, or better a working copy of it, you can reduce the  
amount of X clients, libraries, and servers that get compiled.)

	M-x rename-buffer RET new name RET
	M-x shell RET

A new *shell* buffer would allow you to do other things in it while  
the kernel is compiled in the previous one ...

Thank you, Pete. X11R7.1 or 2 could be big project enough.
Thank you for the response, and now I could get how to rename buffer.

These easiest way to do this is to change the compile line to

cd /path/to/src/ && make -f Makefile ALL

Hi Colin,

That is good idea.

Moreover, I also find I could make it this:
     M-x make RET make -C /usr/src/linux RET
Above make option indicates the root directory for the make no matter
where I am in.

Thank you guys, it was helpful to me.

This would be really limiting at a later date. Better to open the
makefile or the c file you are interested in so emacs deafults to the
right directory when you then make.

Here is my compile command:

(defun my-compile ()
  (lambda ()
    (unless (file-exists-p "Makefile")
      (set (make-local-variable 'compile-command)
	   ;; emulate make's .c.o implicit pattern rule, but with
	   ;; different defaults for the CC, CPPFLAGS, and CFLAGS
	   ;; variables:
	   ;; $(CC) -c -o $@ $(GTKFLAGS) $(CPPFLAGS) $(CFLAGS) $<
	   (let ((file (file-name-nondirectory buffer-file-name)))
	     (format "%s -o %s %s %s %s %s"
		     (or (getenv "CC") "gcc")
		     (file-name-sans-extension file)
		     (or (getenv "GTKFLAGS") "")
		     (or (getenv "CPPFLAGS")"-DDEBUG=9")
		     (or (getenv "CFLAGS") "-std=c99 -pedantic -Wall -Werror -Wshadow -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wconversion  -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -Wnested-externs -Winline -g")
		     file)))))
  )
