I have a verilog module in a file named with extension .v that instantiates a module defined in a file named with extension .sv. In the .v file I use AUTOINST to instantiate the module from the .sv file. I run xemacs in batch mode to expand the autos. Emacs/verilog-mode gets an error saying "Can't locate module-name module definition. Check the verilog-libraray-directories variable. ...

The .sv file defining this module is in the same folder as the .v file that instantiates it. I am using verilog-mode.el verilog-mode-version (substring "$$Revision: 660 $$"

Does verilog-mode work with a mix of .v and .sv files in this way?

Thanks.

That should work.

Verilog-library-extensions already includes .sv by default, so perhaps you're overriding it or verilog-library-flags, or your site startup file doesn't setup verilog-mode for .sv files. When you load the file by hand does it indicate "(Verilog)" in the Emacs mode line?

Does it work interactively? M-x verilog-goto-defun can be used to debug locating of modules.

If you think everything is otherwise right at your end, make an example that fails using --batch --no-site-start and I'll take a look.

I was able to get this to work by changing the way I invoke xemacs. Previously, the command line I have used for years has had no problems like this issue. My old batch mode command line is:
xemacs -batch my_verilog_file.v -l $HOME/.emacs -l verilog-mode.elc -f verilog-mode -f verilog-auto -f save-buffer

If I omit "-l verilog-mode.elc" and reorder it slightly to:
xemacs -batch -l $HOME/.emacs my_verilog_file.v -f verilog-mode -f verilog-auto -f save-buffer

then it works.

Glad you found it.

From your solution, your .elc file was probably from an older version than the .el. Delete it.

Also, I'd suggest -f verilog-batch-auto. That replaces all of the other -f's, see the FAQ.
