Compile mode in emacs!!

Compile mode in emacs!!

[elxsian]

When I try to use the compile mode in emacs, it picks up the default gcc (/usr/bin/gcc). I need it to pick the gcc in a different location. How do I do that? I tried sourcing the path from the compile mode, but did not help. 

Thanks in advance

Set path or PATH in the shell from which you launch GNU Emacs or in  
your login shell accordingly. Or set an environment variable CC that  
points to the compiler you want to use. Makefile can also set which  
compiler will be used ...

And finally you can correct what M-x compile RET does by inserting in  
the read-area (mini-buffer), just an example:

Thanks for your reply Peter.
The path in the shell is already set to the required compiler. I need to run
a set of make files.
I do not want to change the "CC" in the make files.
But , when I say which gcc in the Mx- compile:
It says "/usr/bin/gcc"
I want to use, say "/tools/gnu/gcc". (THe shell from which emacs is laucnhed
points to this gcc! )
Can I configure the emacs to pick the required compiler?

Thanks again,
Nazir

So the question is, why has GNU Emacs another another PATH value  
active? Do launch it from some menu? I looks as if your login shell  
provides a different environment than what you use in an interactive  
shell. If you fix this issue, then GNU Emacs will find the same  
compiler as you in some shell.

As I showed in my examples: you can use env to set particular  
environment variables.

Then my guess is that some environment variables reset the value. You  
can, for example do M-x compile RET and then erase the default make  
command and substitute it with env or printenv to see which  
environment the compile process sees. Then some corrections can be made.

I don't see this. There is a customisation group for the compilation  
process (C-h f compile RET and you'll find a hint in the *Help*  
buffer or via menus Options -> Customize Emacs -> Specific Group…,  
name completion works), but there is nothing to set the compiler  
explicitly. This is done in the shell or in Makefiles, as determined  
by a configure script for example, or set by the programmer.

Hi Peter,

Oops!! ... when I said "printenv", in the Mx-compile, it shows a different
value for "PATH", from the one I see in the terminal.

I guess, you are right. Could you please tell me how to fix this?
Infact, when I said "printenv", I saw a big list, where in PATH_USER had the
correct value, where as the PATH variable was referring to an incorrect
value.
I also changed the path in Mx-compile, using "setenv PATH <value>", but it
gets reset to a different value!!

Thanks,
Nazir

Determine what your login shell is. Set in its RC file PATH to the  
value PATH_USER shows. Log off and in. Enjoy the change.

"Setenv" is a shell command in (t)csh. You have to use 'env  
<VARIABLE>=<value>' ...

What is your login shell? Without some basics nothing reasonable can  
be achieved.

What is your command to "open emacs?"
Do you have a file ~/.emacs_tcsh? This one sets values for GNU Emacs'  
*shell* buffer – but not for what is done via M-x. In case your login  
shell is tcsh, then ~/.cshrc is executed, when it exists. If it does  
not exist, then ~/.tcshrc is executed, if existing. And it is this  
order in which they are loaded, or not loaded (you can proof by  
creating a simple ~/.cshrc with only one line

	echo "Hi, it's me, your ~/.cshrc!"

). Do they manipulate path? The lower case word ``path´´ is the  
variable that sets PATH, which exists in (t)csh only for backward  
compatibility with Bourne shell look-alikes.

If the GNU Emacs binary is launched from a shell as 'emacs &' than no  
other file is involved in setting PATH – except you have in some  
ELisp file a statement like

	(setenv "PATH" (concat "/some/directory" ":" (getenv "PATH")))

or such. This modulates GNU Emacs' internal private environment which  
is then copied into every new process, like for example the  
compilation process.

If the 'emacs' from 'emacs &' is a shell script, than this shell  
script can re-set PATH for the GNU Emacs launched later from this  
script.


This code in site-start.el can name in *Messages* buffer all ELisp  
files loaded:

	(defadvice load (before debug-log activate)
	  (message "(Tipp von Kai G) Now loading: %s" (ad-get-arg 0)))

You can use some for GNU Emacs options to make it not loading ELisp  
files, -q or -Q. Check with 'emacs --help' for the exact meaning! You  
might be able to find circumstances under which GNU Emacs'  
environment is correct.


In Mac OS X I have it very simple and comfortable: an XML file  
contains environment variables and their values and by a command like

	    set path=(`defaults read ~/.MacOSX/environment PATH | tr ':' ' '`)

I can use them in any shell ...

IMHO, the best approach is to learn how to use make.  Then let emacs do 
the default (run make) and put details like paths, command line options, 
etc., in the makefile.

And is this executable "emacs" a binary, a shell script, a sym-link  
to whatever?

You can set in Lisp a PATH environment variable:

	(setenv "PATH" "the right one")

but this can be dangerous when you change path or PATH for your login  
and interactive shells.

I suppose so.

GNU Emacs should inherit this value. Therefore I am asking another  
time if your "emacs" command is some shell script that manipulates  
path or PATH.

It is non-trivial to get emacspeak to run on a windows platform. The first
problem you will have is the TTS driver code. This is written in Tcl. So, you
will either have to install Tcl for Windows (and I don't know anything about
Tcl for windows) or re-write the Tcl code using another scripting language. How
difficult this would be depends on the TTS engine you plan to use. If its a
hardware synthesiser connected to a serial port etc, it probably wouldn't be
that hard. However, if its a software synthesiser, it cold be more difficult if
you want to embed the synthesiser into the driver code (which is how the
current Tcl drivers work for some of the software synths, like IBM's ViaVoice). 

If you are able to get Tcl working for windows, you will probably have to
modify the code to cater for platform differences in things like directory path
seperators, device names etc. One nice thing about Tcl is that it is possibly
the easiest language to link with a C/C++ library (i.e. for the software speech
synth). I briefly had a look at doing the same with Perl, but ran into quite a
few problems because the automated header generation didn't like the C code in
the library I was trying to link with. 

There was an emacspeak driver written in C as an experiment some years back, so
you could write one in C, C# or even Java, but you will need good (fast)
regular expression library. The driver code (i.e. Tcl library and scripts) is
pretty straight forward and it wouldn't e too difficult to translate that to
another language. Emacs communicates with the driver via stdout/stdin, so there
are no real complications there. 

In summary, theoretically, it can be done, but you need to come up with new TTS
drivers and whatever language you choose, it will need regular expression
support and possibly the ability to link with C and C++ TTS libraries or use
their APIs. 

There is an emacspeak mailing list at emacspeak@cs.vassar.edu
