SoX Resampler Library Copyright (c) 2007-13 robs@users.sourceforge.net
SoX Resampler Library Copyright (c) 2007-16 robs@users.sourceforge.net
Cmake is able to configure, build (as either a DLL or a static library),
and install libsoxr for general use on MS-Windows as on other OSs.
However, for projects that prefer to maintain a more monolithic build
structure using the MSVC compiler, the accompanying files may be useful.
Cmake is the recommended way to configure, build (as either a DLL or a static
library), and install libsoxr for general use on MS-Windows, as on other OSs.
* libsoxr.vcproj Builds a static lib for MSVC ver >= 9 (2008).
* soxr-config.h Pre-configured for a typical Win32 system.
However, building within MS Visual Studio is also possible, as exemplified by
the accompanying files:
* soxr-config.h Pre-configured for a modern Win32 system.
* libsoxr.vcproj Builds the library as a DLL, per above.
* libsoxr.sln, Build an example exe using the above.
example1.vcproj
The following notes apply to adaptation of these files:
* For a system without AVX support, set WITH_CR64S to 0 in
soxr-config.h and exclude the three files ...64s.c from the build.
* If changing libsoxr.vcproj to build a static library, then also
remove the preprocessor definition: SOXR_DLL.
