Some problems of Emacs on my OS X 10.8.5

Some problems of Emacs on my OS X 10.8.5

[Haomin Long]

Hello!
Recently I use Emacs 24.3 on my OS X 10.8.5.
To debug, I installed GNU GDB 7.7  from homebrew.
But in Emacs I can't use M-x gdb. It just showed "No such file or
directory, gdb" in the minibuffer.
I typed "M-! echo $PATH" and it did show the directory that containing the
GDB program.
So I typed "M-! gdb ***". After that it did execute GDB , but the first
line of it is "(gdb) quit"!!
I searched a lot at Google but I'm not able to solve it.
Is it some kind of Bug?
THANKS!

I believe Emacs uses the variable `exec-path` to find executables, rather than the env $PATH from shell.

This [script](https://github.com/purcell/exec-path-from-shell) might helps.

So the problem with OSX is that the .profile script is not executed when
you login. This is different from GNU Linux distributions which execute
.bashrc when you log in. .profile is only executed when you run a shell. If
you launch emacs from outside the shell, i.e., clicking an icon on your
desktop or via the dock (which I do), .profile isn't loaded.

the environment plist file is what OSX uses to setup it's environment when
you "log in":

~/.MacOSX/environment.plist

I am still with Snow Leopard, Mac OS X 10.6.8, but I think the use of this file ended in Lion, Mac OS X 10.7. Later Launchservice must be used – and configured.

It's likely that GNU Emacs' internal variable exec-path might be set to a different value than PATH in some interactive shell… It might help to create a wrapper shell script "Emacs" in /Applications/Emacs.app/Contents/MacOS for the then renamed Emacs.bin that the launched process Emacs.bin has the same environment as an interactive shell. XQuartz uses such a concept.
