libuv
libuv is a platform layer for node.js. Its purpose is to abstract IOCP on Windows and epoll/kqueue/event ports/etc. on Unix systems. We intend to eventually contain all platform differences in this library.

Build Instructions
For GCC there are two methods building: 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
Windows
First, Python 2.6 or 2.7 must be installed as it is required by GYP.
Also, the directory for the preferred Python executable must be specified
by the PYTHON or Path environment variables.
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:
$ mkdir -p build
$ git clone https://git.chromium.org/external/gyp.git build/gyp
Unix
Run:
$ ./gyp_uv -f make
$ make -C out
OS X
Run:
$ ./gyp_uv -f xcode
$ xcodebuild -project uv.xcodeproj -configuration Release -target All
Android
Run:
$ source ./android-configure NDK_PATH gyp
$ make -C out
Note for UNIX users: compile your project with -D_LARGEFILE_SOURCE and
-D_FILE_OFFSET_BITS=64. GYP builds take care of that automatically.
Supported Platforms
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.
