Re: [Confuse-devel] Need help with libconfuse

[Martin Hedenfalk]

Hi,

Yes, there could be errors in your config file. Or in the program. Or a 
bug in the library.

LibConfuse can't find the option in it's list (the cfg_opt_t array 
passed to cfg_init). If there is an option not found, libConfused will 
print an error and abort.

Check the spelling, upper/lower case, etc.
