libuv is a new platform layer for Node. 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.
Non-blocking TCP sockets
Non-blocking named pipes
Child process spawning
Asynchronous DNS via
Asynchronous file system APIs
High resolution time
Current executable path look up
Thread pool scheduling
ANSI escape code controlled TTY
File system events Currently supports inotify,
ReadDirectoryChangesWand kqueue. Event ports in the near future.

For GCC (including MinGW) there are two methods building: via normal makefiles 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. The old (more stable) system is using Makefiles.
To build via Makefile simply execute:
To build with Visual Studio run the vcbuilds.bat file which will checkout the GYP code into build/gyp and generate the uv.sln and related files.
Windows users can also build from cmd-line using msbuild. This is done by running vcbuild.bat from Visual Studio command prompt.
To have GYP generate build script for another system you will need to checkout GYP into the project tree manually:
svn co http://gyp.googlecode.com/svn/trunk build/gyp
Unix users run
./gyp_uv -f make make
Macintosh users run
./gyp_uv -f xcode xcodebuild -project uv.xcodeproj -configuration Release -target All
Note for Linux users: compile your project with
-D_GNU_SOURCE when you
uv.h. GYP builds take care of that automatically. If you use
autotools, add a
AC_GNU_SOURCE declaration to your
Microsoft Windows operating systems since Windows XP SP2. It can be built with either Visual Studio or MinGW.
Linux 2.6 using the GCC toolchain.
MacOS using the GCC or XCode toolchain.
Solaris 121 and later using GCC toolchain.
