What do you do to compile C files?

That would be ~/.emacs

This is not emacs lisp syntax, but Common Lisp syntax.  Therefore you
will have to install a Common Lisp implementation.

C. GCC. Emacs, ... Windows 7?!

Better to switch to a real OS. Especially if you are
into C.

Then you need a Makefile, and some source. Run
`compile' when you are done.

Some things I found useful:

    (setq compilation-scroll-output t)
    (setq compilation-mode-hook 'visual-line-mode)
    (setq compile-command "make -j 4 -s -k")
    (setq compilation-read-command nil) ; use `compile-command'

That's all there is to it.

What do you want to do? Add two to a complex number?
The #c(0 1.0) is used in Common Lisp: it doesn't work
in Elisp. I can't help you, but probably Emacs Calc
can do it; perhaps there you can learn how to use it
in Elisp code.

Well, they had to use two mirrors, making sure to turn off the light

How to build the C language environment in Emacs?

[Liu Shengyu]

Dear 
I have learned Emacs for a few days by myself.
And I have been read some books about simply uses of Emacs.
But I have some questions about how to use it practically.
My computer is not MAC, and my system is Windows 7.


1.    I have been installed MinGW in my computer, and I have been checked in MSDOS, and also have been set envionment variables in PATH.
But I still can't compile C file. 
Emacs tells that gcc is not a internal or external command.
I think maybe I need to write some commands in ~.emacs to combine GCC and Emacs, but i don't know to do it.
So can you help me about this question?


2.    I wanna compile (+ #c(0 1.0) 2)
But Emacs tells me that Debugger entered--Lisp error: (invalid-read-syntax "#")
Why this simply syntax # is not a built-in syntax in my Emacs.
How to solve this kind of problem?


Best wishes.
Thanks for your attention.

In fact, maybe you can try to use the full path to your compiler. If it
works, then you can make an alias.

The built-in lisp in Emacs is elisp...

Re: How to build the C language environment in Emacs?

[Grant Rettke]

Easiest thing to do is to install Vagrant and boot up a Linux box
there to get Emacs and a C compiler.

Not as easy as in GNU/Linux, but fairly good nonetheless. The "problem"
Emacs has on Windows is external dependencies. Tools such as `grep' are
always intalled on a GNU/Linux box, but you do have to install them
yourself on Windows. Those tools are not hard requirements for a working
Emacs, though.

Others mentioned Cygwin and IMHO it is the wrong solution. MSYS2 is
better because it doesn't pretend that Windows is a POSIX system.

I use emacs on Windows and it's nearly the same as Unix.  Some of the 
PrintScreen ScrollLock Pause key chords don't work quite the same. 
Otherwise, emacs is emacs.

I also recall using Emacs in Windows unpleasant to say
the least.

Emacs is Emacs to some extent but Emacs doesn't exist
in a vacuum. If you use it on Windows you will miss
out a lot: convenience (everyone assumes you're on
some Unix); you miss out culture and technology.

And especially if you are into C - which is the number
one *system* programming language. It shares history
with UNIX, not to mention it is the language the
system is written in (including today's Linux).

There is no reason to use Windows for no reason, only
do it if your family is starving or your job is
super-exciting (like some science project where some
specific software is Windows-only and too intense for
wine and the like - but then you can still beam the
results to your Linux box and use Emacs to compile the
report - like I always said, computing is creative :))

Yeah, using Emacs in Windows is OK, except for missing many things...

But in my Windows, I still install Emacs since no other editors satisfy
me. :)

Well, in fact, in order to visit some websites, I need Windows because
they are IE only...

Ahh, I know virtual machines. I have been using it, so I do not open my
Windows for several months :)

After all, having a Windows is necessary...But I hope someday I can
uninstall it.

Can you both provide hard facts instead of vague FUD about what makes
Emacs on Windows an unpleasant experience?

My Emacs setup is far from trivial and I couldn't say on which OS I am
using by just observing how I interact with Emacs. Gnus, Org, Evil,
Magit, AUCTeX, a dozen minor packages, 2000+ lines on .emacs and coding
on multipe programming languages, all is the same, except for the few
customizations that tells Emacs the directories where certain
executables and data files are stored.

I have been in exactly this discussion before. Even
then there were people who said it isn't the same at
all (and provided examples), and there were also
people who got agitated and said "its exactly the
same, what are you talking about, oh oh oh".

I can mention dozens of things that are different
running Emacs in a Linux VT compared to running it on
Windows. Probably hundreds but I stopped doing it on
Windows after two or three days and I won't do it
again.

But what is different: the colors and how to set them
up, retrieval and installation of Emacs itself, how to
invoke it, how you get additional software (e.g.,
LaTeX components, and Emacs-w3m), what such software
is available, how Emacs interacts with the rest of the
system - it doesn't have to be IPC with named pipes or
anything that fancy (but that would be different as
well, because of the different OS models) - it can be
as simple as the clipboard interaction with tmux and
X, all that just recently discussed would be totally
unapplicable; the keys, and how to setup special keys;
not to mention Windows in itself as a laughably
bloated and annoying system with popups and nuclear
wars all the time running amok in the, eh,
"background".

Windows is a joke. No excuses!

The only remote relation with Emacs usability is the lack of a package
management system on Windows (well, we have MSYS2 now, but still no
match for a Linux distro.) The rest of your diatribe consists on
"Windows is not Linux and I like Linux very much, therefore Windows is
garbage." (colors? keys? IPC? what are you talking about?)

I'll be charitable and assume that your entire message is a joke.

Please stop spreading misinformation about the usability of Emacs on
Windows. You are damaging the Emacs project and insulting those who
contributed countless hours of their time to Emacs Windows support.

Indeed.  I've been using Emacs under Windows for around 15 years now,
and wouldn't dream of using anything else.  Thank you Emacs developers
for providing a powerful editor that that can be used so effectively
under *both* Unix-type OS's *and* Windows.

You make that sound minor. I would say its a big plus for linux.

But we are not comparing Windows vs. Linux. I'm disputing the claim that
"using Emacs on Windows is terrible". If the issue is the lack of a
package system, Emacs is not different from any other Windows
application.

It's minor because it's not needed on Windows.

I can't say I know the Windows editor world. Is Vim on
Windows? ("Wim"?)

The MS GUI IDEs (e.g., Access, VB5) do come with their
own editors, of course - very annoying because an
editor should let you do *all* editing, otherwise you
won't learn "everything" by doing "something" (or at
the very least it will come much, much slower).

Ha ha, stop it. There are no such sites. If there are,
I don't want to know their contents...

Using VMs with Windows I actually do think counts as
using Windows :)

How about today?

Remember: "What you once feared know makes you free -
do it today, in a different way."

Windows is absolutely not necessary. Food and shelter
and are necessary. Go to San Fernandez and find out.
God helps those who help themselves. He is especially
grateful to folks who do different, difficult things,
and if they do them long enough he rewards them with
skills and self-confidence: and much better tools, of
course.

I have experienced those first hand too.  Usually because the large
corporate employer I worked for used them for my payroll.  Meaning
that I could only ignore the IE only site if I didn't want my
paycheck.  If I wanted my paycheck then it was required to use IE to
talk to the IE only company payroll website.

Now that I have pulled the ejection handles and left the large
corporate employer I can blissfully ignore those abominations.  But I
still feel sympathy for those trapped in the system and the choice is
either stand on principle or feed the family.  Given that choice most
people suck it up, swallow their principles, and run IE to put food on
the table.

Unfortunately, I have to confirm the sightings of these...  Not exactly
my payroll, but some e-learning materials (not done by me) which had
good content, but ran only on IE.

Online banking websites in large swathes of Asia. Try getting around
that!

Actually I take that back, the advent of Android apps has obviated the
problem to a large extent.

I worked for a company that had a complicated and finicky web-based
system for submitting expenses claims.  Some of it only worked in IE and
other bits of it only worked properly in Firefox.  It was necessary to
close the session in one browser and re-open it in another to file a
claim of any complexity.

I use emacs on Windows and Linux, and even share 99% of my .emacs.  I 
frankly don't see what's missing.

Can you compile from the cmd window?  If you cannot, then your MinGW
installation is broken, and this is not an Emacs problem.  You need to
fix that first.

If you can compile from the cmd window, but not from Emacs, then your
PATH and the list of directories where Emacs looks for programs are
different.  To make them identical, do NOT change PATH from the cmd
window, but instead from the Computer Properties, in the Advanced
section.
