Hi everyone,
I am building my emacs on the bas of the [nano-
emacs](https://github.com/rougier/nano-emacs)  of Nicolas Rougier. I
am testing several of his own config features, and I get this error.

With debug init, I get this:

```Debugger entered--Lisp error: (void-function org-make-tags-matcher)
(org-make-tags-matcher "*") (cdr (org-make-tags-matcher "*")) (defvar
my/org-imenu-filter-function (cdr (org-make-tags-matcher "*")) "Filter
function to decide if a headline is kept") load-with-code-
conversion("c:/Users/f/.emacs.d/init.el" "c:/xxxxx/.emacs.d/init.el" t
t) load("c:/Users/f/.emacs.d/init" noerror nomessage) startup--load-
user-init-file(#f(compiled-function () #<bytecode 0xe158b6316c5d54c>)
#f(compiled-function () #<bytecode -0x1f3c686ddc0da035>) t) command-
line() normal-top-level()```

I looked into the help, the variable exists, it comes with org.el. I
looked into org.el and found the variable... I do not understand why I
am getting this error.

Any idea? Thx!

Did you check for variable of function? What happens if you evaluate
`(org-make-tags-matcher "*")`

Bonjour Nicolas,

I get the same kind of error:

`Debugger entered--Lisp error: (void-function org-make-tags-matcher)
(org-make-tags-matcher "*") eval((org-make-tags-matcher "*") t) eval-
expression((org-make-tags-matcher "*") nil nil 127) funcall-
interactively(eval-expression (org-make-tags-matcher "*") nil nil 127)
call-interactively(eval-expression nil nil) command-execute(eval-
expression)`

I also tried using your config directly: I get the very same error.

I am no specialist in lisp... thanks for your support

Can you try to add `(require 'org)` before?

Hello,
Thanks for your reply.
I added it right at the beginning of the source block where ```org-
make-tags-matcher``` is located, without any luck.
I'll try to add it earlier in the code.
I'll keep you posted.
Thanks

Hi, I finally managed to get rid of the error, by adding ```require
'org``` at zhe beginning of the config.
Thanks for the tip, and congrats for your work! Nano-emacs is a gem!
