Hi,

I am trying to build a package called Tkpng, which depends on zlib.
But, when I extracted the files from the .tgz file for this package,
it does not contain zlib folder. Have you experienced any issue like
this? Do you know where one can get zlib files?

On make, it is complaining:

tkImgPNG.c
generic\tkImgPNG.c(18) : fatal error C1083: Cannot open include file:
'zlib.h':
No such file or directory

Does anyone how can I resolve this issue?

Thanks,
Mona.

Thanks.
Now, when I am building, I get the below link errors. Any ideas how I
can resolve these?

rm -f tkpng09.dll

You have to compile zlib, and link with the produced zlib library.

Always read error messages (especially from a linker) like a love letter!

Note the referenced '/lz' as an unrecognized option ...

'-lz' in a *nix based system implies that libz.[so|a|o] exists somewhere
where your linker can find it. You will need to put the libz.dll or
whatever windows compiler will name it in a location that it can be found,
and point your linker to it an a manner consistent with object files ...

Cheers,
Rob.
