Building libharu with Visual Studio 2019

Precondition

• libharu ver2.3.0: http://libharu.org/
• zlib ver1.2.11: https://zlib.net/
• libping ver1.6.37: http://www.libpng.org/pub/png/libpng.html

It required that libpng and zlib has been built with VS2019. Reference: Building libpng with Visual Studio 2019

The required directory structure is here.

    libharu-VisualStudio2019/             # root for building
    ├─ libharu-RELEASE_2_3_0/             # libharu
    ├─ lpng1637/                          # libpng (NOT included in this repository)
    └─ zlib-1.2.11/                       # zlib (NOT included in this repository)

Build libharu

1. Copy libpng and zlib
   libpng: Copy "libpng16.lib" and "zlib.lib" from "libpng-VisualStudio2019\lpng1637\projects\vstudio\x64\Release Library" to "libharu-VisualStudio2019\libharu-RELEASE_2_3_0"

2. Edit Script
   Open file "libharu-VisualStudio2019\libharu-RELEASE_2_3_0\script\Makefile.msvc_dll".
   Edit as below.

   • Line #14 PNG_PREFIX = ../../libpng to PNG_PREFIX = ../lpng1637

   • Line #18 ZLIB_PREFIX = ../../zlib to ZLIB_PREFIX = ../zlib-1.2.11

   • Line #30 CFLAGS=/MD -nologo -O2 -Iinclude -Iwin32\include -I"$(PNG_PREFIX)"\include -I"$(ZLIB_PREFIX)"\include -DHPDF_DLL_MAKE to CFLAGS=/MD -nologo -O2 -Iinclude -Iwin32\include -I"$(PNG_PREFIX)" -I"$(ZLIB_PREFIX)" -DHPDF_DLL_MAKE

   • Line #33 LDFLAGS= /LIBPATH:$(PNG_PREFIX)\lib /LIBPATH:$(ZLIB_PREFIX)\lib /LIBPATH:win32\msvc libpng13.lib zlib.lib to LDFLAGS= /LIBPATH:$(PNG_PREFIX)\lib /LIBPATH:$(ZLIB_PREFIX)\lib /LIBPATH:win32\msvc libpng16.lib zlib.lib

3. Build with MS Build in Visual Studio 2019 Tools
   Launch "x64 Native Tools Command Prompt for VS 2019" and change directory to "build\libharu-RELEASE_2_3_0"
   Type below and Enter
   

   nmake -f script\Makefile.msvc_dll
   

   When the build is completed, you can see the below message.
   

   Finished generating code
           rename libhpdf.lib libhpdf.lib
           copy libhpdf.dll demo
           1 file(s) copied.

   The directory structure after building is here.
