Building PHP. Clean builds. Noisy redefines.

there is a very small set of people with karma there and even fewer who
care about windows compiler warnings.

...but many read patches sent to internals@ (especially people with
karma) and could commit them after reviewing :)

And a few might even grant karma after they saw a few good patches for
that area...

Hi Richard,

Hmmm - I don't get the first set of long to short warnings - what
compiler/sdk are you using?

Just a quick note to say that I'm not seeing a lot of the warnings you
describe, either. In fact the only place I see a lot of compiler warnings
is in ext/date. So please add your compiler version to the description,
because those fixing the problems you describe may otherwise assume all
Windows builds are affected when they are not.

I am using Microsoft Visual C++ 2008 Express Edition with the Windows
Server 2008 and .NET 3.4 SDK.

Richard.

SDKs\Windows\v6.1\include\sdkddkver.h(186).
This 1 #define causes a LOT of noise during compilation. I know I
could suppress all the warnings, but with so much noise, how does
anyone see the true warnings in the noise?

By adding a #undef _WIN32_WINNT before #define _WIN32_WINNT 0x0400,
this removes the warning. It is more or less every .c compile.

Did I get you right ?

Yes on the patch. There are a few more like this. It is just a cosmetic issue.

I am using Microsoft Visual C++ 2008 Express Edition with the Windows
Server 2008 and .NET 3.4 SDK.

I'm NOT running Apache (so runtime version issues there don't apply),
and I am only playing/learning - this is going nowhere near my
live/dev servers. Just learning.

My next goal is to get a version of Linux so I can build and test my
suggestions on 2 platforms. Hopefully, my patches/suggestions will
have more support!

Thank you.

Richard.

I applied something slightly different, the define is only needed for
old versions of Windows that lack it.

Scott was faster than me and committed slightly different patch =)

Greetings,
I'm also having some fun with php devel on windows and I just would
like to report that along with _WIN32_WINNT there are few others macro
redefinitions. Here is the warnings I saw on last compilation...
I'm using the MSVC++ Express Edition, .Net 3 on XP Professional.
