Zlib tests fail: zlib version mismatch!

[Krognol]

echoing zlibVersion gives me 1.2.8.

Running
Nim 0.17.0
Windows 10

Works fine on my linux vm. I guess my zlib version is outdated? Where does Nim even look for .dll's?

[fabianallendorf]

Is there a way to fix this yet? I have the exact same problem. Even when I download a newer zlib version, it errors with could not load zlib1.dll

@Papanoah that seems like a different error. Are you sure the DLL's architecture matches your executable? (the DLL could be 64 bit whereas your exe is 32 bit).

[fabianallendorf]

@dom96 It's true, i've tried it with 32 bit dlls apparently. However, each 64bit zlib version from 1.2.7 up to 1.2.11 produces the version error. I'm not really into this issue but judging from the zlib doc, this may have something to do with z_stream size difference.

Z_VERSION_ERROR: The version requested is not compatible with the library version, or the z_stream size differs from that used by the library.

Same as #39 and #53. The error is because the ZStream struct is badly defined and has the wrong size on LP64 OSs.
