libpng-src

Helper Cargo package for compiling libpng into a static C library. Meant to be used as build dependency for dufferent -sys or -vendored packages. Does not provide directly usable libpng functionality or bindings.

Provided version

Compiles libpng with version 1.6.43. Original source code with the license is provided in libpng folder without any modifications.

Currenlly supported OS and targets

Expected to work for:

Linux: x86_64-unknown-linux-gnu, aarch64-unknown-linux-gnu (no cross-compilation supported yet)
Windows: x86_64-pc-windows-msvc, aarch644-pc-windows-msvc (no cross-compilation supported yet)
macOS: x86_64-apple-darwin, aarch64-apple-darwin
iOS, including simulators (cross-compilation from macOS host): x86_64-apple-ios, aarch64-apple-ios, aarch64-apple-ios-sim

Tested before upload for all the targets, except aarch64-unknown-linux-gnu and aarch64-pc-windows-msvc.

Dependenencies for hosts

Doesn't depend on any cargo packages for compilation. Uses CMake and libpng provided shell scripts. Depends on zlib library headers for compilation and dynamic library artifact for testing.

Linux

CMake - install via https://cmake.org/ or a package manager
make - https://www.gnu.org/software/make/
CC - a C compiler, added to system path
zlib - https://packages.debian.org/bullseye/zlib1g-dev

Windows

CMake - vendored by MS Visual Studio;
MS Visual Studio - https://visualstudio.microsoft.com/
`zlib headers and tests helping DLL - vendored in the package

Invoke Cargo via Developer Powershell or Developer Command Prompt for correct work.

macOS and iOS

CMake - install via https://cmake.org/ or Homebrew;
make - vendored by OS
Xcode - https://developer.apple.com/xcode/
zlib` - vendored by OS

Testing

One of the unit tests invokes CTest (part of CMake) under the hood for testing native code.
