Emacs 24.4 W32/W64
I'm trying to run Clozure Common Lisp under Emacs / Slime.
Slime lauches CCL and starts the Swank server.
When the process is started by Emacs, I get an error with this backtrace :
? ;Loading #P"c:/Home/.emacs.d/vendor/slime/swank-loader.lisp"...
> Error: Le fournisseur de services demandé n’a pas pu être chargé ou

The same thing works if I run OpenCL from the console.
How the fact that the process is run from Emacs could
result in an error from make-tcp-socket ?
Conflict with the winsock2 dll which is loaded by both process ?
I have tried many combinations of CCL and emacs :
- Emacs 24.4 32 bits (GNU version)
- Emacs 24.4 64 bits (my version)
- OpenCL 64 bits (official 1.10 version)
- OpenCL 64 bits (compiled by me with the same toolchain used to compile
Emacs)
- OpenCL 32 bits
I couldn't find a working version. Any idea on how to hunt this ?
Best regards,

For French-challenged people, this message in English means "The
requested service provider could not be loaded or initialized."

Does this happen in "emacs -Q"? Do you have an emacs-server running?

If "emacs -Q" shows the same problem, I'd suggest using SysInternals
tools to find what exactly happens and why. ProcessExplorer and
ProcessMonitor come to mind.

Thanks.
Here is what process explorer shows about the process environment :
[image: Images intégrées 1]
It seems to confirm this diagnostic (found with Google, same symptoms,
different context) about the 10106 error :
" On Windows, if the environment is not copied the SYSTEMROOT environment
variable won't be available and PHP will have problems loading Winsock."
So it seems that OpenMCL is run without inheriting any environment, which
is not good.
I don't see (yet) why the environment is not inherited.

Can you describe how does Emacs invoke OpenMCL, exactly? IOW, with
which Emacs command it is invoked, does the invocation go through a
shell (and if so, which shell), etc.

Problem closed.
OpenMCL is started by comint-exec. The process-env variable was trashed by
a spurious Slime configuration variable of mine.
You can actually do :
(let ((process-environment (append "foo=bar" process-environment)))
process-environment)
(102 111 111 61 98 97 114
"TEXINPUTS=.;c:/Home/.emacs.d/elpa/auctex-11.88/latex;" ...
:-( I'm not sure if something can be done at the emacs level to check that
this sensitive variable is not destroyed.
For the record, it it useful to know that this 10106 winsock error relates
to SYSTEMROOT environment variable being not defined.
Once the environment is properly passed to comint-exec, everything works as
expected.

We definitely could degrade more gracefully: we should signal an
error when faced with a process-environment that is not a list of strings.
