Description:
------------
Environment: Windiows Server 2012 R2 + VS2015 Update 3

I tried to build PHP with master branch latest revision on Windows.It failed to build due to link error LNK2001: unresolved external symbol inflateValidate. This issue can be reproduced form master branch revision 347b880 (https://github.com/php/php-src/commit/347b880ee4081140f488916a40ff6f2765a69e43).

It failed when execute the following link command. Could you please take a look at this? Thanks!

Thanks for the report. Please update the deps. Also, with master, please use vc15, and do a clean rebuild of at least ext/zlib, but better full.

Thanks.

Hi, ab@php.net 

Thanks for your reply. It seems the problem should be that:
1. In file ext\zlib\php_zlib.def, it exports function "inflateValidate".
2. In file ext\zlib\php_zlib.h, there is no definition for function "inflateValidate",

I think this is the root cause for the link error LNK2001. Any thought please let me know. Thank you so much!

Hi, ab@php.net 

The "inflateValidate" is added into file ext\zlib\php_zlib.def recently. I looked at the other functions defined in php_zlib.def and found that they’re all defined in x86\deps\include\zlib.h. I then looked at this file and all definitions of functions in php_zlib.def are in here…except "inflateValidate". 

We follow the instruction on https://wiki.php.net/internals/windows/stepbystepbuild to build PHP.

We get the deps from http://windows.php.net/downloads/php-sdk/deps-master-vc14-x86.7z. The deps-master-vc14-x86.7z\deps\include\zlib.h file has no definiton for "inflateValidate". Do we get the deps from wrong place? If yes, where can we get the right deps?

@seaheart_2006 thanks for the further info. You should've seen the notes on the wiki, that 7.2 requires the new SDK. I just made it bold on the wiki page. But anyway, you should be following https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2 instead of the old page. FYI, 7.2 == master. The deps-master-vc14-x86.7z is likely outdated and contains an older zlib version which indeed doesn't have `inflateValidate`. Please follow the new build instructions page and use `phpsdk_deps -u -b master` to fetch the deps, this will get you a suitable set of vc15 dependencies. Alternatively, you can fetch single packages from http://windows.php.net/downloads/php-sdk/deps/vc15/ for now.

Thanks.

FYI, i've upgraded the 7zips, so you can fetch them as well with the today's state, if you need for whatever reasons.

Thanks.

Really appreciate your help! After replace the deps files, I can build PHP successfully. Thanks again!
