Inform 7 is the most widely used interactive fiction (i.e. text adventure game) authoring system available today. This repository contains the Windows front-end that represents the user interface that users of Inform work with:

Download and install Visual Studio 2019 Community edition from https://visualstudio.microsoft.com/. In the installer, under "Workloads", make sure that "Desktop development with C++" is selected, and under "Individual components" that the following are selected:

• C++ MFC for latest build tools (x86 & x64)
• C++ Clang Compiler for Windows
• C++ Clang-cl

Install git. I use the version of git that is part of Cygwin, a Linux-like environment for Windows, but Git for Windows can be used from a Windows command prompt.

Open the environment that you are using git from (e.g. Cygwin), and switch to the root directory that the build environment will be created under (from here referred to as "<root>"). Clone this and the other required repositories with git:

git clone https://github.com/DavidKinder/Windows-Inform7.git Adv/Inform7
git clone https://github.com/DavidKinder/Windows-Glk.git Adv/Glk
git clone https://github.com/DavidKinder/Windows-Frotz.git Adv/Frotz
git clone https://github.com/DavidKinder/Git.git Adv/Git
git clone https://github.com/DavidKinder/Libraries.git Libraries
git clone https://github.com/erkyrath/glulxe.git Adv/Glulxe/Generic

Download and install the latest release of Windows Inform 7 from https://github.com/DavidKinder/Windows-Inform7/releases/ and copy everything in the installation directory to "<root>/Adv/Inform7/Build", but do not over-write any existing files.

Download the latest version of zlib from https://zlib.net/. Unpack the archive and copy the contents of the top-level directory to "<root>/Libraries/zlib".

Download the latest version of libpng from http://www.libpng.org/pub/png/libpng.html. Unpack the archive and copy the contents of the top-level directory to "<root>/Libraries/libpng". Copy the file "<root>/Libraries/libpng/scripts/pnglibconf.h.prebuilt" to "<root>/Libraries/libpng/pnglibconf.h".

Open "<root>/Libraries/libpng/pnglibconf.h" in a text editor, and find and delete all lines that define symbols starting with "PNG_SAVE_", "PNG_SIMPLIFIED_WRITE_" and "PNG_WRITE_".

Download libjpeg 6b from http://libjpeg.sourceforge.net/. (Later versions are available, but maintenance of libjpeg seems to have been taken up by someone other than the original authors, who has some distinctly odd ideas.)

Unpack the archive and copy the contents of the "jpeg-6b" directory to "<root>/Libraries/jpeg". In "<root>/Libraries/jpeg", rename "jconfig.vc" to "jconfig.h".

Open "<root>/Libraries/jpeg/jmorecfg.h" in a text editor, and find

#ifndef XMD_H			/* X11/xmd.h correctly defines INT32 */
typedef long INT32;
#endif

Change it to

#if !defined(XMD_H) && !defined(_BASETSD_H_)
typedef long INT32;
#endif

In the same file, find

#ifdef NEED_FAR_POINTERS
#define FAR  far
#else
#define FAR
#endif

Change it to

#ifndef FAR
#ifdef NEED_FAR_POINTERS
#define FAR  far
#else
#define FAR
#endif
#endif

Download the latest stable versions of libogg and libvorbis from https://xiph.org/downloads/. Unpack the libogg archive and copy the contents of the top-level directory to "<root>/Libraries/libogg". Unpack the libvorbis archive and copy the contents of the top-level directory to "<root>/Libraries/libvorbis".

Download the latest release of hunspell from https://github.com/hunspell/hunspell/releases/. Unpack the archive and copy the contents of the "src/hunspell" directory to "<root>/Libraries/hunspell".

Download the latest stable build of CEF for Windows 64-bit from https://cef-builds.spotifycdn.com/index.html. The minimal distribution is sufficient. Unpack the archive and copy the contents of it to "<root>/Libraries/libcef".

Start Visual Studio, open the solution "<root>/Adv/Inform7/Inform7/Inform7.sln", then build and run the "Inform7" project.

To build the interpreters that drive the "Story" tab, in Visual Studio open the solution "<root>/Adv/Inform7/Interpreters/Interpreters.sln", then build projects it contains.
