# Makefile for NufxLib using Microsoft Visual C++.  This builds the library
# as a static lib and as a DLL, and builds all samples.  The test-basic
# sample is built twice, once with the static lib, and once with the DLL.
#
# Tested with VS 2013 Pro.  From the "VS2013 x86 Native Tools Command
# Prompt", run "nmake -f makefile.msc".
#
# If you're including zlib support, place copies of zlib.h, zconf.h,
# and the zlib library in this directory.
#
# Adapted from zlib's Makefile.msc.

# C compiler flags
# -Fd: rename PDB file from "VCx0.pdb" (where 'x' is the version number);
#      allows DLL debug info to be separate from app debug info
# -Ox: full optimization
# -Oy-: disable frame pointer omission (for easier debugging)
# -MD: create a multithreaded DLL using MSVCRT.lib; alternatively,
#      use -MDd to create a debug executable with MSVCRTD.lib
# -nologo: suppress display of copyright banner
# -W3: set warning level to 3 (all production-level warnings)
# -Zi: generate a PDB file with full debugging info
#
# The OPTFLAGSTR define is used by Version.c to show how the library was
# built.  Defining NUFXLIB_EXPORTS enables the __declspec(dllexport)
# macros that are required for creating the DLL.
