emacs won't run

emacs won't run

[Andrea Venturoli]

Hello.

Since a bit, emacs won't start under X: no error, no message, nothing. 
It just starts and exits after a while without doing anything.

I can run "emacs -nw" fine.

How can I diagnose this? Is there any log I can look into? Any utility?

  bye & Thanks
	av.

Wouldn't "cygcheck /usr/bin/emacs" be a better first step?  It sounds like
it could be a missing DLL.

likely it is a missing/wrong DLL, but he mentioned that
"emacs -nw" is working, so should be not a static one and
cygcheck could miss the issue.

Thanks.
Forgive my noobiness, but...

 > strace emacs
 > strace.exe error creating process emacs, (error 2)

Of course, emacs is a shell script.

So I run "strace emacs-x11": is this ok?



Running emacs-x11 by itself I get one of two behaviours:
a) either it hogs the CPU for some seconds, then quits with no effect at 
all;
b) or it hogs the CPU for a while, then I'll get "Memory exhausted--use 
M-x save-some-buffers then exit and restart Emacs".

I still can't grasp what makes the difference.



Running it through strace, however, it never exits (still doing nothing 
appreciable); it is also quite hard to kill.



In the end I got a trace file (which is over 7MB!), but it's nothing I 
can interpret.
What should I do?
Anything I should look for?
Any way to make some sense out of this?
Should I upload it somewhere for someone who might be interested in 
seeing it?

  bye & Thanks
	av.

additonal you can upload the trace file somewhere, so someone could take 
a look

Both files are here:

Thanks to anyone who helped me so far or will look into this in the future.

Try from mintty window running emacs without X and without start files:
     emacs -nw -Q
See if other X apps run:
     xterm
There should be no errors running the above.

Thanks.
As I said in previous post, "emacs -nw" works, as do other X apps 
(including xterm).

Is possible install bash 4.2 on cygwin? Is there some patch or update for it?

Thanks

It is available for 64-bit. Not 32-bit though, we're still waiting for
that update (with the WORDEXP_OPTION enabled to fix wordexp(3) and
enabled support for loadable builtins)...

You could probably find a 32-bit version in cygwinports.

Cheers,
Peter

Is it available for 64-bit? I installed CygWin and searched the
package for bash 4.2 and I just found Bash 4.1.

Hi!

Sorry about that, I knew the 64-bit version was newer and was convinced
it was 4.2-something. So convinced that I didn't check before writing.

Cheers,
Peter

Hello

Then, is not possible install bash 4.2 on CygWin?. I can not
understand if there is some way for it.

Thanks :)

We have a program called setup-*.exe which installs programs.  If you
don't see bash 4.2 there then it is not available for installation.
There isn't any secret way to get other versions of programs than what
is available via setup.

You could presumably build bash 4.2 yourself, however.

This is the return of "INVALID_OBJECT" if an invalid pointer is passed
to a thread routine.

I just took a second look at your strace output, and I saw the same font 
issue as the one here:

   http://cygwin.com/ml/cygwin/2013-12/msg00248.html

Try the remedy I suggested there.

The instructions linked here solved the problem running emacs-x11 for
me under cygwin-x86_64:

I suggest that you delete the directories ~/.fontconfig and
~/.cache/fontconfig. Then run (as administrator) "fc-cache -fsv".

Of course it should be a symlink, pointing to emacs-X11 on a standard
installation.  Did you read /usr/share/doc/emacs/README.Cygwin?  Is the
DISPLAY environment variable set correctly?  Does Emacs "run" when you start
it as "emacs-X11 -Q"?

Achim.

Right.
It's a symlink to a symlink:

Then I would have expected strace to accept it, but it doesn't matter 
really.

Now yes, thanks.

I think so.

$ env|grep DISPLAY
DISPLAY=:0.0

No luck.
It either hangs, hogging the CPU, or quits without doing anything.

I don't know if this explains your emacs problem, but the group 
"mkgroup" indicates that /etc/group (and possibly /etc/passwd) should be 
rebuilt  Don't you get a message about this when you start a shell?

I don't get any such message.

"mkpasswd -l" won't list me, since I'm a domain user.
"mkpasswd -l -D", "mkpasswd -l -D domain", "mkpasswd -l -d" and 
"mkpasswd -l -d domain" all end with error 2221.

"mkgroup -l -D >/etc/group" (run elevated) updated my /etc/group.

Still no luck with emacs-x11.

That's weird.  I never saw that happen with the -d/-D option.  Especialy
because mkpasswd -d/-D doesn't rely on any user name, it just asks the
domain controller to list the domain accounts using the NetUserEnum
function, and NetUserEnum is not documented to be able to return
error 2221 (NERR_UserNotFound) at all.  Are you running this under a
domain account?

Re: emacs won't run

[David Karr]

Are you running it from the desktop from "run"?  I discovered the same
thing.  One workaround that worked for me was to open a rxvt window
and then run emacs from that. However, an even better workaround was
simply using the "w32" version and bypassing X entirely. When I
changed my "run" shortcut to run "emacs-w32" instead, it works fine.

I tried from xterm or "Cygwin Terminal".

I know, but this is not the exactly the same.
