zlib 121 warnings

[Dennis Passmore]

Why do I see the following warnings when compiling v304 with Delphi 7 and "zlib121" defined?

kpUnzipp.Pas(1344)
VCLUnZip.pas(3091) Warning: Bad global symbol definition: '_z_errmsg' in object
file 'C:\Projects\Common\VclZip Pro\src\zlib121\zutil.obj'
VCLUnZip.pas(3091) Warning: Bad global symbol definition: '@zcalloc' in object
file 'C:\Projects\Common\VclZip Pro\src\zlib121\zutil.obj'
VCLUnZip.pas(3091) Warning: Bad global symbol definition: '@zcfree' in object
file 'C:\Projects\Common\VclZip Pro\src\zlib121\zutil.obj'
VCLUnZip.pas(3094)

Not sure. I don't remember ever seeing those. I'll play with it tonight and see if I do get them.

Does it work ok when you do link in 1.2.1?

Dennis,

Actually it turns out that the link to zutil.obj is not needed at all. You can go into VCLUNZIP.PAS to line 495 and remove

{$L zlib121\zutil.obj}

and that will get rid of the warnings.

That works.

Thanks for the good support.

Also, you might be interested to know that FastZLib object files are now available for zlib 1.2.1. They weren't available when I built the object files included with the VCLZip distribution. So if you like to use the FastZLib object files they can be found at:

Just replace the ones in the zlib121 subdirectory with these. It should work fine.
