On Windows, zlib is pretty much a mess. The only modern project files are for building a DLL that uses the WINAPI calling convention for Visual Basic applications, and the default Makefile doesn't handle debug builds, or create properly versioned DLL and import library names. Short of a total rewrite, I built this by manually adjusting the makefile with different settings, running a build, and then copying the output files into separate directories.

Copying OpenSSL's sound versioning discipline, they also just added two entry points to a patch release.
First I do the 32-bit Release build:
Edit win32/Makefile.msc and change:
IMPLIB
=zlib1.lib
SHAREDLIB=zlib1_2.dll
nmake /f win32\Makefile.msc
mkdir Release
copy zlib1.* Release
nmake /f win32\Makefile.msc clean
Now, the 64-bit Release build, switching to the x64 Tools command prompt:
mkdir x64
mkdir x64\Release
nmake /f win32\Makefile.msc
copy zlib1.* x64\Release
nmake /f win32\Makefile.msc clean
Now the 32-bit Debug build, switching to the 32-bit Tools command prompt:
- Edit win32/Makefile.msc and change:
IMPLIB
=zlib1D.lib
SHAREDLIB
to zlib1D-
SHAREDLIB
=zlib1_2D.dll
- Change
CFLAGS
and turn/MD
into/MDd
, and add-D_DEBUG
toWFLAGS
nmake win32/Makefile.msc
mkdir Debug
copy zlib1D.* Debug
nmake /f win32\Makefile.msc clean
Now, the 64-bit Debug build, switching back to the x64 Tools command prompt:
mkdir x64\Debug
nmake /f win32\Makefile.msc
copy zlib1D.* x64\Debug
nmake /f win32\Makefile.msc clean
The following files dependencies subdirectory of the cpp-msbuild project can be used to automate the build:
to set up the environment..\cpp-msbuild\dependencies\
config.bat..\cpp-msbuild\dependencies\zlib.bat
to create the modified makefiles (requires 'sed' on the path)X86 build (requires the appropriate VS command line):
Code Block ..\cpp-msbuild\dependencies\zlib-compile.bat .
X64 build (requires the appropriate VS command line):
Code Block ..\cpp-msbuild\dependencies\zlib-compile.bat x64
