Build Status

Build status

GYP can Generate Your Projects.

It is a pre-build system that uses a json config to generate optimized project files for various build tools like make, xcode, visual studio.

For example, it is able to generate make or scons files that run fast.

It is also able to generate xcode and visual studio files.

It's a bit like cmake, except: http://code.google.com/p/gyp/wiki/GypVsCMake

This demo shows how to build:

  • a hello world c++ library (called 'mylib')
  • a command line program that uses/links to it
  • a node.js module that depends on mylib via it gyp file

Usage

Just grab this sample project and build it:

git clone git://github.com/springmeyer/hello-gyp.git
cd hello-gyp
make

To learn more about how to do this manually, or for different plaforms, read on.

make

The below commands assume you have gyp installed globally. You can do this like:

git clone https://chromium.googlesource.com/external/gyp.git
cd gyp
sudo python setup.py install

build

gyp mylib.gyp --depth=. -f make --generator-output=./build/makefiles
V=1 make -C ./build/makefiles/

test

$ ./build/makefiles/out/Release/myapp
hello

And the node module:

npm install node-gyp
node_modules/.bin/node-gyp configure build

Test the node module:

$ node -e "console.log(require('./build/Release/modulename.node').hello())"
hello

scons

build

gyp mylib.gyp --depth=. -f scons --generator-output=./build/sconsfiles
scons -C ./build/sconsfiles/

test

$ ./build/sconsfiles/Release/myapp
hello

xcode

build

gyp mylib.gyp --depth=. -f xcode --generator-output=./build/xcodefiles
xcodebuild -project ./build/xcodefiles/mylib.xcodeproj

test

# xcode does not respect subdirectory so `build` goes into the main directory
$ ./build/Release/myapp
hello

ninja

Ninja is a build system designed to be ultra fast.

Install it like:

git clone git://github.com/martine/ninja.git
cd ninja
./bootstrap.py
cp ninja /usr/local/bin/

Make sure it works:

$ ninja
ninja: no work to do.

Now go back to the hello-gyp project folder and build the sample:

gyp mylib.gyp --depth=. -f ninja
ninja -v -C out/Release/ -f build.ninja

test

$ ./out/Release/myapp
hello

Microsft Visual Studio C++ 2010 Expres

Note, this assumes you've downloaded and installed the free 2010 C++ studio.

python gyp/gyp mylib.gyp --depth=. -f msvs -G msvs_version=2010
msbuild mylib.sln

test

c:\hello-gyp>Release\myapp.exe
hello

Others

Other formats are some some gyp-specific debugging output
