Thanks for testing, should be fixed by af94f77.

Got another error, thanks for your efforts here

I think I know what's going on now. 1bfabb2 should fix it. Thanks!

[casouri]

Actually hold for a minute, it still have problems with gcc.

[casouri]

Maybe give it a try. The gcc on my linux server and clang on my Mac can compile just fine, but the gcc I installed on my Mac gives errors.

Hi! I'm trying to build the module as well on Linux and I get the following error :

From my understanding, there's something wrong about the function definition and the exception but since I do not use C/C++ it's difficult to tell.

[casouri]

It should be fixed now. Could please you verify that for me?

[Nathan-Furnal]

Yes it does! Thanks a lot =) I had to build the ~/.deft/db by hand though as it error'ed out when I hadn't.

Also, here is my current config in case someone wants to try it out.

(use-package "xeft"
  :load-path "site-lisp/xeft"
  :ensure nil
  :defer t
  :custom
  (xeft-directory "~/projects/notes")
  :commands (xeft))

[casouri]

Ah, it didn't auto create the database because you put the database and notes in different directories. I've fixed that problem. Thanks for reporting!

[Nathan-Furnal]

Thanks for replying so quicky!

[tareefdev]

I have built the module using the latest version and it went flawlessly. Thanks.
