Starting with version 1.0.0 libuv follows the semantic versioning scheme. The API change and backwards compatibility rules are those indicated by SemVer. libuv will keep a stable ABI across major releases.
Official API documentation
Located in the docs/ subdirectory. It uses the Sphinx framework, which makes it possible to build the documentation in multiple formats.
Show different supported building options:
$ make help
Build documentation as HTML:
$ make html
Build documentation as man pages:
$ make man
Build documentation as ePub:
$ make epub
NOTE: Windows users need to use make.bat instead of plain 'make'.

For GCC there are two build methods: via autotools or via GYP. GYP is a meta-build system which can generate MSVS, Makefile, and XCode backends. It is best used for integration into other projects.
To build with autotools:
$ sh autogen.sh $ ./configure $ make $ make check $ make install
To build with Visual Studio, launch a git shell (e.g. Cmd or PowerShell) and run vcbuild.bat which will checkout the GYP code into build/gyp and generate uv.sln as well as related project files.
To have GYP generate build script for another system, checkout GYP into the project tree manually:
$ git clone https://chromium.googlesource.com/external/gyp.git build/gyp OR $ svn co http://gyp.googlecode.com/svn/trunk build/gyp
$ ./gyp_uv.py -f make $ make -C out
./gyp_uv.py -f make -Dtarget_arch=x32 to build [x32] binaries.
$ ./gyp_uv.py -f xcode $ xcodebuild -ARCHS="x86_64" -project uv.xcodeproj \ -configuration Release -target All
$ brew install --HEAD libuv
Note to OS X users:
Make sure that you specify the architecture you wish to build for in the "ARCHS" flag. You can specify more than one by delimiting with a space (e.g. "x86_64 i386").
$ source ./android-configure NDK_PATH gyp $ make -C out
Note for UNIX users: compile your project with
-D_FILE_OFFSET_BITS=64. GYP builds take care of that automatically.
$ ./gyp_uv.py -f make $ make -C out $ ./out/Debug/run-tests
Microsoft Windows operating systems since Windows XP SP2. It can be built with either Visual Studio or MinGW. Consider using Visual Studio Express 2010 or later if you do not have a full Visual Studio license.
Linux using the GCC toolchain.
OS X using the GCC or XCode toolchain.
Solaris 121 and later using GCC toolchain.
