zlib 1.2.5 – fatal error LNK1120: X unresolved externals

When trying to link program to zlib 1.2.5 static library (zlib.lib), I got the following error:
fatal error LNK1120: X unresolved externals ...

Version 1.1.3 worked without any problems. Without going into details, here is what I did – using DUMPBIN.EXE I figured out that I am using __cdecl (/Gd) Calling convention, but zlib somehow overrides it with __stdcall (/Gz). Two hours letter I found that Visual Studio 2010 solution (zlib-1.2.5\contrib\vstudio\vc10\zlibvc.sln) has definition ZLIB_WINAPI.

Removing ZLIB_WINAPI solved my problem. To remove, it go to:
zlibstat Properties – Configuration Properties – C/C++ – Preprocessor – Preprocessor Definitions

Alternatively, you can comment out ifdef block – #ifdef ZLIB_WINAPI.

IPv6, literals and legacy software

IPv4 address exhaustion is slowly going into final phase.

To use IPv6 addresses in legacy software, some mechanism must be in place to not confuse programs with colons (:) in the addresses. For Windows this is IPv6 literals.

We have created IPv6 to literal online converting tool. It is a free tool to convert IPv6 to literal address ending with .ipv6-literal.net

For example, these two lines behave identically:
ping 0--1.ipv6-literal.net ping ::1

Also, zone ID is supported and shortest / longest IPv6 address form is calculated.

Use form below, if you have suggestions or comments.

UPDATE Apr 26, 2011. As Takyoji suggested, just added support for Reverse DNS lookup. Now last row is calculated for use with the special domain ip6.arpa.
