Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

Issue: The build failed because the function declaration differs from the actual function call later. This kind of error may appear when the default language version for C compilation is changed from -std=gnu17 to -std=gnu23. In C17 and earlier, function declarators in form of rettype identifier(); specified no information about the number or types of the parameters while in C23 such declarations mean (void) i. e. a function taking no arguments.
Resolution: Code relying on a non-zero number of parameters can be fixed by adding the correct parameters to the function declaration. In other cases the code may be simply missing a #include of the correct header and can be fixed by including the correct header and removing the declaration. Alternatively you can use -std= to select an earlier version of C standard or report the issue upstream.
