Re: [Minios-devel] [UNIKRAFT/LIBZLIB PATCH v3 2/3] Add Makefile.uk

[Felipe Huici <Felipe.Huici@xxxxxxxxx>]

Hi,

    Hi Felipe,
    
    You have some warnings when building zlib. Some of them are inoffensive
    and need to be suppressed by copying SUPRESSED_FLAGS from here
    https://github.com/clupuishere/pcre/blob/master/Makefile.uk#L72 . But
    the -Wimplicit-function-declaration warnings are there because zconf.h
    header doesn't exist - it is generated by `./configure` command so maybe
    you should also add a prepare rule to run it (another option would be
    simply committing the zconf.h in the glue).

Ok, I'll add a prepare rule.
    
    Please see another minor one inline.

    Nitpicking: you have some extra whitespaces at the end of the line
    above. If we use this zlib port as an example we might propagate this in
    other external libs as well.

Ok :), will fix.
