Hi there,

I hope this is the right place to raise this, but I've had an issue 
opening .tex files with the new emacs.  On 24.5.1 everything opened fine 
and I was able to edit and typeset as usual with C-c C-c.

Now however, I get the following error:

File mode specification error: (dbus-error No connection to bus :session)

And the file opens in fundamental mode.

I'm happy to help in any way I can.

Many thanks


Dave

How did you obtain your Emacs binary?  Emacs with Dbus is known *not* to
work on Windows.  I suggest you grab a binary built `--without-dbus',
put (pdf)latex in your PATH and try again.

Best, Arash

Hi Dave,

I use the binary from

https://sourceforge.net/projects/emacs-bin/

on my Windows 7, and it works out of the box (make sure to 
run addpm.exe from the bin folder).

Hope this helps.
Cheers,
J

You can find out how Emacs was built by checking this variable:

,----[ C-h v system-configuration-options RET ]
| system-configuration-options is a variable defined in ‘C source code’.
| Its value is
| "... --without-imagemagick --without-dbus ..."
| 
| Documentation:
| String containing the configuration options Emacs was built with.
`----

You can try to delete `libdbus-*.dll' in your Emacs/bin directory, maybe
that prevents Emacs from using DBus [1].

[Message part 1 (text/plain, inline)]

Aha, many thanks!

Running that on my last working copy (25.0.50.1) gives:

"--prefix=/z/emacs --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 
--build=x86_64-w64-mingw32 --with-wide-int --with-jpeg --with-xpm 
--with-png --with-tiff --with-rsvg --with-xml2 --with-gnutls 
--with-sound=yes --with-file-notification=yes --without-dbus 
--without-imagemagick 'CFLAGS=-O3 -fomit-frame-pointer -g0 -pipe' 
'LDFLAGS=-static-libgcc -static-libstdc++ -static -s -Wl,-s'"

Which as you see, contains "--without-dbus".

The latest one I've downloaded is much simpler:

"--prefix=/tmp/emacs --without-imagemagick 'CFLAGS=-O2 
-fomit-frame-pointer -g0'"

So that will be the problem.  Many thanks for your help, I'll try and get 
a version with the correct settings.

Cheers


Dave
