The latest PhysicsFS information and releases can be found at:
https://icculus.org/physfs/
Building is (ahem) very easy.
ALL PLATFORMS:
Please read the text file LICENSE.txt in the root of the source tree.
The license is extremely liberal, even to closed-source, commercial
applications.
If you've got Doxygen (http://www.doxygen.org/) installed, you can run it
without any command line arguments in the root of the source tree to generate
the API reference (or build the "docs" target from your build system). This
is optional. You can browse the API docs online here:
https://icculus.org/physfs/docs/
BUILD IT WITH YOUR OWN PROGRAM:
If you don't care about formal packaging: just add everything in the "src"
directory to whatever you use to build your program and compile it along with
everything else, and you're done. It should compile with any reasonable
ANSI C compiler, should build cleanly even with excessive compiler warnings
enabled, needs no extra configuration, and allows static linking.
WinRT and Haiku need C++ compilers for their system APIs, but if you aren't on
these platforms and don't have a C++ compiler, don't build the .cpp files.
Likewise: Apple platforms (macOS, iOS, etc) need an Objective-C compiler, but
if you aren't on these platforms and don't have a Objective-C compiler, don't
build the .m file. Everything you need is in the .c sources.
If this all worked for your specific project, you can stop reading now.
UNIX:
You will need CMake (https://www.cmake.org/) 2.4 or later installed.
Make a directory, wherever you like. This will be your build directory.
Chdir to your build directory. Run "cmake /where/i/unpacked/physfs" to
generate Makefiles. You can then run "ccmake ." and customize the build,
but the defaults are probably okay. You can have CMake generate KDevelop
or Ninja project files or whatever, if you prefer these.
Run "make". PhysicsFS will now build.
As root, run "make install".
If you get sick of the library, run "make uninstall" as root
and it will remove all traces of the library from the system paths.
Once you are satisfied, you can delete the build directory.
Primary Unix development is done with GNU/Linux, but PhysicsFS is known to
work out of the box with several flavors of Unix. It it doesn't work, patches
to get it running can be sent to icculus@icculus.org.
Windows:
If building with Cygwin, mingw32, MSYS, or something else that uses the GNU
toolchain, follow the Unix instructions, above.
If you want to use Visual Studio, nmake, or the Platform SDK, you will need
CMake (https://www.cmake.org/) 2.4 or later installed. Point CMake at the
CMakeLists.txt file in the root of the source directory and hit the
"Configure" button. After telling it what type of compiler you are targeting
(Borland, Visual Studio, etc), CMake will process for while and then give you
a list of options you can change (what archivers you want to support, etc).
If you aren't sure, the defaults are probably fine. Hit the "Configure"
button again, then "OK" once configuration has completed with options that
match your liking. Now project files for your favorite programming
environment will be generated for you in the directory you specified.
Go there and use them to build PhysicsFS.
PhysicsFS will only link directly against system libraries that have existed
since Windows NT 3.51. If there's a newer API we want to use, we try to
dynamically load it at runtime and fallback to a reasonable behaviour when
we can't find it. Note that Windows 98 and later _should_
work if you use the Microsoft Layer for Unicode (UNICOWS.DLL) to provide
some missing system APIs, but this is no longer tested as of PhysicsFS 2.1.0.
PhysicsFS 2.0.x is known to work with Windows 95 without UNICOWS.DLL.
PhysicsFS works on 32-bit and 64-bit Windows. There is no 16-bit Windows
support at all. Windows RT is covered below.
Windows RT:
Windows RT (Windows Phone, Windows Store, UWP) 8.0 and later are supported.
Make sure you include both physfs_platform_windows.c _and_
physfs_platform_winrt.cpp in your build, and that the C++ file has
"Consume Windows Runtime Extension" set to "Yes" in its Visual Studio
properties (from the command line, you want to compile this file with the
"/ZW" compiler switch). CMake can, in theory, generate a project file for
WinRT if you pick a recent Visual Studio target, choose manual cross-compile
options, and set the system name to "WindowsPhone" or "WindowsStore" and the
correct OS version (8.0 or later).
PocketPC/WindowsCE:
Support for PocketPC was removed in PhysicsFS 2.1.0. This was known to work
in the 1.0 releases, but wasn't tested in 2.0 and later. PhysicsFS should
work on modern Windows Phones (see "Windows RT" section).
macOS:
You will need CMake (https://www.cmake.org/) 2.4 or later installed.
You can either generate a Unix makefile with CMake, or generate an Xcode
project, whichever makes you more comfortable.
PowerPC and Intel Macs should both be supported.
MAC OS 8/9 ("Mac OS Classic"):
Classic Mac OS support has been dropped in PhysicsFS 2.0. Apple hasn't updated
pre-OSX versions in more than a decade at this point, none of the hardware
they've shipped will boot it for almost as many years, and finding
developer tools for it is becoming almost impossible. As the switch to Intel
hardware has removed the "Classic" emulation environment, it was time to
remove support from PhysicsFS. That being said, the PhysicsFS 1.0 branch can
still target back to Mac OS 8.5, so you can use that if you need support for
this legacy OS. We still very much support modern macOS, though: see above.
Emscripten:
Use the "Unix" instructions, above. You can install the Emscripten SDK and use
the extras/buildbot-emscripten.sh script to automate this for you.
BeOS, Zeta, YellowTab:
BeOS support was dropped in PhysicsFS 2.1.0. Consider installing Haiku, which
we still support.
Haiku:
Use the "Unix" instructions, above.
OS/2:
OS/2 is known to work with OpenWatcom and GCC-based compilers. I couldn't get
an OS/2 port of CMake to generate OpenWatcom project files (although it should
be able to do that in theory), it should be able to do Unix Makefiles with
GCC. It might be easier to just compile PhysicsFS along with the rest of
your project on this platform.
OTHER PLATFORMS:
Many Unix-like platforms might "just work" with CMake. Some of these platforms
are known to have worked at one time, but have not been heavily tested, if
tested at all. PhysicsFS is, as far as we know, 64-bit and byteorder clean,
and is known to compile on several compilers across many platforms. To
implement a new platform or archiver, please read the heavily-commented
physfs_internal.h and look at the physfs_platform_* and physfs_archiver_*
source files for examples.

The API documentation is readable in a few ways:
- Read physfs.h; it's _heavily_ documented and the primary source of reference
documentation for the library.
- Run Doxygen over the header, which produces nicer-to-browse documentation in
HTML, LaTeX, manpage, etc formats. This is done for you if Doxygen is
installed and you build the "docs" target in whatever project files CMake
generated for you.
- Too much trouble? We generated the HTML reference for you, online here:
https://icculus.org/physfs/docs/
- We would love well-written tutorials for the latest version of PhysicsFS!
If you write one, we would love to list it here. Drop me a line about it:
icculus@icculus.org ... Thanks!

Stuff that needs to be done and wishlist:
These are in no particular order.
Some might be dupes, some might be done already, some might be bad ideas.
From https://icculus.org/pipermail/physfs/2009-March/000698.html ...
- Write support for various archives. I haven't decided how to do this yet,
but I'd like to.
- Add an API to expose a file's extended attributes to the application?
- Deprecate PHYSFS_setSaneConfig(). It really should have been in the extras
directory.
- Clean up the sources to match my ever-changing coding style. :)

From https://icculus.org/pipermail/physfs/2010-January/000833.html ...
- SWIG bindings
From old TODO.txt...
- Other archivers: perhaps tar(.gz|.bz2), RPM, ARJ, etc. These are less
important, since streaming archives aren't of much value to games (which
is why zipfiles are king: random access), but it could have uses for, say,
an installer/updater.
- Do symlinks in zip archiver work when they point to dirs?
- Enable more warnings?
- Use __cdecl in physfs.h?
- Look for FIXMEs (many marked with "!!!" in comments).
- fscanf and fprintf support in extras dir.
- Sanity check byte order at runtime.
- Memory locking?
- General code audit.
- Multiple write dirs with mount points?
Other stuff I thought of...
- moar asserts!
- constify!
- Does iPhone work?
- Fix CMake vs Doxygen.
- Doxygen replacement? (manpages suck.)
- Fix coding standards to match.
- See if we can ditch some #include lines...
- LZMA support in zip archiver?
- bzip2 support in zip archiver?
- Reduce the BAIL and GOTO macro use. A lot of these don't add anything.
- Change the term "search path" to something less confusing.
Probably other stuff. Requests and recommendations are welcome.

There used to be C# bindings in this directory, but they have been
unmaintained for many years.
Instead, there is a more modern PhysicsFS wrapper for .NET available.
You can find it at https://github.com/frabert/SharpPhysFS
Thanks to Francesco Bertolaccini for his efforts on that project!

*
* This function is equivalent to PHYSFSEXT_enumerateFilesWildcard(). It

* There is no sorting done at this level, and if you need that, you should
* probably use PHYSFS_enumerateFilesWildcard() instead, which guarantees
* alphabetical sorting. This form reports whatever is discovered in each
* archive before moving on to the next. Even within one archive, we can't
* guarantee what order it will discover data. <em>Any sorting you find in
* these callbacks is just pure luck. Do not rely on it.</em> As this walks
* the entire list of archives, you may receive duplicate filenames.
*
* Wildcard strings can use the '*' and '?' characters, currently.
* Matches can be case-insensitive if you pass a zero for argument 3.
*
* \param dir Directory, in platform-independent notation, to enumerate.
* \param wildcard Wildcard pattern to use for filtering.

/**
* \mainpage PhysicsFS ignorecase
*
* This is an extension to PhysicsFS to let you handle files in a
* case-insensitive manner, regardless of what sort of filesystem or
* archive they reside in. It does this by enumerating directories as
* needed and manually locating matching entries.
*
* Please note that this brings with it some caveats:
* - On filesystems that are case-insensitive to start with, such as those
* used on Windows or MacOS, you are adding extra overhead.
* - On filesystems that are case-sensitive, you might select the wrong dir
* or file (which brings security considerations and potential bugs). This
* code favours exact case matches, but you will lose access to otherwise
* duplicate filenames, or you might go down a wrong directory tree, etc.
* In practice, this is rarely a problem, but you need to be aware of it.
* - This doesn't do _anything_ with the write directory; you're on your
* own for opening the right files for writing. You can sort of get around
* this by adding your write directory to the search path, but then the
* interpolated directory tree can screw you up even more.
*
* This code should be considered an aid for legacy code. New development
* shouldn't do things that require this aid in the first place. :)
*
* Usage: Set up PhysicsFS as you normally would, then use
* PHYSFSEXT_locateCorrectCase() to get a "correct" pathname to pass to
* functions like PHYSFS_openRead(), etc.
*
* License: this code is public domain. I make no warranty that it is useful,

/* We build three simple hashmaps here: one that maps Unicode codepoints to
a one, two, or three lowercase codepoints. To retrieve this info: look at
case_fold_hashX, where X is 1, 2, or 3. Most foldable codepoints fold to one,
a few dozen fold to two, and a handful fold to three. If the codepoint isn't
in any of these hashes, it doesn't fold (no separate upper and lowercase).
Almost all these codepoints fit into 16 bits, so we hash them as such to save
memory. If a codepoint is > 0xFFFF, we have separate hashes for them,
since there are (currently) only about 120 of them and (currently) all of them

* This is a quick and dirty HTTP server that uses PhysicsFS to retrieve

*
* Basically, you compile this code, and run it:
* ./physfshttpd archive1.zip archive2.zip /path/to/a/real/dir etc...
*
* The files are appended in order to the PhysicsFS search path, and when
* a client request comes in, it looks for the file in said search path.
*
* My goal was to make this work in less than 300 lines of C, so again, it's
* not to be used for any serious purpose. Patches to make this application
* suck less will be readily and gratefully accepted.

* GRP support routines for PhysicsFS.

* This driver handles BUILD engine archives ("groupfiles"). This format

*
* The format is simple enough. In Ken's words:
*
* What's the .GRP file format?
*
* The ".grp" file format is just a collection of a lot of files stored
* into 1 big one. I tried to make the format as simple as possible: The
* first 12 bytes contains my name, "KenSilverman". The next 4 bytes is
* the number of files that were compacted into the group file. Then for
* each file, there is a 16 byte structure, where the first 12 bytes are
* the filename, and the last 4 bytes are the file's size. The rest of
* the group file is just the raw data packed one after the other in the
* same order as the list of files.

/*
* WAD support routines for PhysicsFS.
*
* This driver handles DOOM engine archives ("wads").
* This format (but not this driver) was designed by id Software for use
* with the DOOM engine.
* The specs of the format are from the unofficial doom specs v1.666
* found here: http://www.gamers.org/dhs/helpdocs/dmsp1666.html
* The format of the archive: (from the specs)
*
* A WAD file has three parts:
* (1) a twelve-byte header
* (2) one or more "lumps"
* (3) a directory or "info table" that contains the names, offsets, and
* sizes of all the lumps in the WAD
*
* The header consists of three four-byte parts:
* (a) an ASCII string which must be either "IWAD" or "PWAD"
* (b) a uint32 which is the number of lumps in the wad
* (c) a uint32 which is the file offset to the start of
* the directory
*
* The directory has one 16-byte entry for every lump. Each entry consists
* of three parts:
*
* (a) a uint32, the file offset to the start of the lump
* (b) a uint32, the size of the lump in bytes
* (c) an 8-byte ASCII string, the name of the lump, padded with zeros.
* For example, the "DEMO1" entry in hexadecimal would be
* (44 45 4D 4F 31 00 00 00)
*
* Note that there is no way to tell if an opened WAD archive is a
* IWAD or PWAD with this archiver.
* I couldn't think of a way to provide that information, without being too
* hacky.
* I don't think it's really that important though.
*
*
* Please see the file LICENSE.txt in the source's root directory.

/* tinfl.c v1.11 - public domain inflate with zlib header parsing/adler32 checking (inflate-only subset of miniz.c)
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated May 20, 2011
Implements RFC 1950: https://www.ietf.org/rfc/rfc1950.txt and RFC 1951: https://www.ietf.org/rfc/rfc1951.txt
The entire decompressor coroutine is implemented in tinfl_decompress(). The other functions are optional high-level helpers.
