[flac-dev] [PATCH 0/5] Allow multiple targets to be disabled

Hi,

This patchet allows a few targets to be disabled when unrequired.
The rational is coming from VLC's contrib buildsystem, so far we use make -C
to select only some subparts of the available targets.
It would be easier and cleaner to use autoconf to do so IMHO.

There's an additional patch which fixes the build when building for
WinRT/UWP platform, upstreamed from VLC.
We have a couple more for this platform, but ultimately, I think the proper
solution would be to allow only libflac to be built, as most forbidden function
calls are in the convenience libraries in flac/shared.
I tried to switch those from noinst_LTLIBRARIES to EXTRA_LTLIBRARIES but failed
miserably at doing so :( I'm thinking it would be way easier to achieve by
moving to a non-recursive
automake configuration, but that's kind of an intrusive change; that being
said, I'm willing to do it.

Please let me know what you think!

Regards,

According to  
<http://stackoverflow.com/questions/9509166/what-is-winapifamily-h>
winapifamily.h is only available since MSVS 2012, so build will fail in  
older
versions of Visual Studio (and in some older versions of MinGW).

Apparently these preprocessor defines are from winapifamily.h
so it won't work in older MSVS and MinGW.

Again, doesn't work with older MSVS and MinGW.

Why OutputDebugStringW? MSDN says in  
<https://msdn.microsoft.com/en-us/library/windows/desktop/aa363362(v=vs.85).aspx>:
"Sends a string to the debugger for display. [...] If the application
has no debugger, the system debugger displays the string if the filter
mask allows it. [...] If the application has no debugger and the system
debugger is not active, OutputDebugString does nothing. [...] Applications
should send very minimal debug output and provide a way for the user
to enable or disable its use."
...it doesn't look like a function that simply prints some output from a  
program.


And what's the goal of this patch? To create flac.exe/metaflac.exe that
can work in WinRT? Or to remove build errors, and flac/metaflac are allowed
to work incorrectly?

I think that FLAC sources should remain compatible with Visual
Studio 2010 (and probably earlier), people still need it.
For example: <https://github.com/xiph/flac/issues/23>

Is it possible to simply exclude win_utf8_io.c from compiling
if target OS is WinRT/non-desktop?
