Linking against liblzma
|
||||
-----------------------
|
||||
|
||||
MinGW
|
||||
|
||||
If you use MinGW, linking against liblzma.dll or liblzma.a should
|
||||
be straightforward. You don't need an import library to link
|
||||
against liblzma.dll, and for static linking, you don't need to
|
||||
worry about the LZMA_API_STATIC macro.
|
||||
|
||||
Note that the MinGW distribution includes liblzma. If you are
|
||||
building packages that will be part of the MinGW distribution, you
|
||||
probably should use the version of liblzma shipped in MinGW instead
|
||||
of this package.

Creating an import library for MSVC / Visual Studio
|
||||
---------------------------------------------------
|
||||
|
||||
To link against liblzma.dll, you need to create an import library
|
||||
first. You need the "lib" command from MSVC and liblzma.def from

If you need to link statically against liblzma, you should build
|
||||
liblzma with MSVC 2013 update 2 or later. Alternatively, if having
|
||||
a decompressor is enough, consider using XZ Embedded or LZMA SDK.
|
||||
|
||||
When you plan to link against static liblzma, you need to tell
|
||||
lzma.h to not use __declspec(dllimport) by defining the macro
|
||||
LZMA_API_STATIC. You can do it either in the C/C++ code
|
||||
|
||||
#define LZMA_API_STATIC
|
||||
#include <lzma.h>
|
||||
|
||||
or by adding it to compiler options.

|

Other compilers
|
||||
|
||||
If you are using some other compiler, see its documentation how to
|
||||
create an import library (if it is needed). If it is simple, I
|
||||
might consider including the instructions here.
