Building XZ Utils with Microsoft Visual Studio
==============================================
Introduction
------------
MSVC 2013 update 2 and later have enough C99 support to build
liblzma from XZ Utils 5.2.0 and later without modifications.
Older MSVC versions would require a large number of changes to
the XZ Utils code and thus the old MSVC versions aren't supported.
As of 2015-06-19, some work has been done to get xz.exe and other
command line tools built with MSVC, but it's not complete enough
to be included in XZ Utils.
Building
--------
The following files in this directory are for MSVC:
config.h liblzma configuration #defines for MSVC.
liblzma.vcxproj This builds static liblzma.
liblzma_dll.vcxproj This builds liblzma.dll.
xz_win.sln Solution using the above project files.
The projects have x86 and x86-64 platform configurations, as well
as a Debug, Release, and ReleaseMT configuration -- MT is the
compiler switch to link to the CRT statically, so it will not
have any other DLL dependencies.
Currently no test programs are built or run under MSVC.
MSVC gives a bunch of compiler warnings. Some warnings are specific
to 32-bit or 64-bit build and some appear for both builds. These
are known and shouldn't be a problem. Some of them will probably
be fixed in the future.
Notes
-----
liblzma API headers declare the functions with __declspec(dllimport)
by default. To avoid this when using static liblzma from your code,
#define LZMA_API_STATIC before #including <lzma.h>.
