exec-path not changed in autostart

exec-path not changed in autostart

[Xin Jin]

Hi,
I use the following code to add the paths from the shell environment to exec-path:

(setq exec-path
      (append
       (split-string-and-unquote (getenv "PATH") ":")
       exec-path))

However, it does not work when "emacs24 --daemon" runs as a system autostart script. The interesting thing is that if I run "emacs24 --daemon" manually, the above code does work and the paths are successfully added.

I am really confused. Can anyone see why this happens?

I am running openbox on debian wheezy.

Why do you need that?  exec-path already includes the directories from
$PATH, so the above sounds redundant.

No, it doesn't. I added some paths to $PATH in .bashrc, and clearly they do not show up in exec-path by default.

Hmm, so is that the .bashrc is processed too slowly so that $PATH hasn't updated?

But even if I add (sleep 10s && emacs24 --daemon), it still doesn't work. Maybe I should try longer.

Even sleep 20s does not work.

It is not about of timing. The init scripts execute when the OS starts,
while your .bashrc executes when you log in. The OS will not allow you
to log in until all init scrips are finished executing.

Thanks. Actually I find out that .bashrc executes when a bash process starts, and .bash_profile is the one that starts when I log in.

So the problem is solved after I move the paths from .bashrc to .bash_profile,
