Hi Eli,
Sorry, I should have been more specific. Here's what I did:
1) I wrote an emacs module _mymod.so, as well as wrappers mymod.el (with
some local setup) and mymod-pkg.el (which only has a call to
define-package).
2) I tarred these together to form mymod-0.1.tar
3) I installed the resulting package using M-x package-install-file
In my messages buffer, I see that Emacs tries to generate autoloads for the
.so, and fails with the error indicated in the original email ("_mymod.so:0:0:
error: scan-error: (Containing expression ends prematurely 238020
238021))").
I'm pretty confident that the emacs module is correctly built (I can load
it, and run the functions in it). Also, if I rename _mymod.so to something
else, e.g. _mymod.blablabla, the rest of the package installs correctly and
can be loaded. So it really seems as if Emacs is choking on trying to
generate autoloads for _mymod.so.
Maybe backtracking a little bit:
1) Should Emacs be able to generate autoloads for an .so?
2) Does anybody have any experience with embedding an emacs module in an
emacs package? Any best practices I should be aware of?
Thanks,
Joris.
