最近在研究cocos2d-x，下载下来之后，要在ubuntu上跑起来费了一番功夫。总结以下：
1、下载代码
$ git clone [email protected]:cocos2d/cocos2d-x.git
2、搭建环境
$ cd cocos2d-x/build
$ ./install-deps-linux.sh
3、安装cmake版本和gcc g++版本
要求：
cmake版本：2.8.0
gcc g++版本：4.8.1
4、编译
$ cmake ..
$ make
cmake的时候，ubuntu 10.04很可能遇见如下错误：
CMake Error at CMakeLists.txt:30 (cmake_policy):
Policy "CMP0017" is not known to this version of CMake.
...
CMake Error at cmake/Modules/CocosBuildHelpers.cmake:44 (find_package):

GLEW.
...
CMake Error at cmake/Modules/FindPkgConfig.cmake:163 (include):

/FindPackageHandleStandardArgs.cmake
...
第二个错误中：glew相关的包都已经安装了。
我从android的代码下找了一个FindGLEW.cmake文件，放到了cmake/Modules下面
其他两个错误，我是这样改的：

修改之后cmake不报错，make的时候报错，编译glfw报错：
看报错的信息应该是glfw的版本不对，要去glfw3，但是我电脑上是glfw2
但是apt-get无法安装glfw3，许是ubuntu版本不够高，于是我到glfw.org网站上下了一份glfw3的源代码，然后自己编译。
http://www.glfw.org/docs/latest/compile.html#compile_cmake
然后编译还会报如下错误：
../../lib/libcocos2d.a(CCGLViewImpl-desktop.cpp.o): In function `cocos2d::GLViewImpl::GLViewImpl()':
/home/yinlijun/project/google-code/cocos2d-x/cocos/platform/desktop/CCGLViewImpl-desktop.cpp:287: undefined reference to `glfwSetErrorCallback'

这时应该把本地的glfw2版本完全删除。：
sudo apt-get remove XXX
这还没完，编译到cpp-empty-test的时候，还会报错：
Linking CXX executable ../../bin/cpp-empty-test/cpp-empty-test
/bin/sh: cannot create /Resources: Permission denied

make[1]: *** [tests/cpp-empty-test/CMakeFiles/cpp-empty-test.dir/all] 错误 2
make: *** [all] 错误 2
需要修改如下：
yinlijun@brn-yinlijun:cocos2d-x$ git diff tests/cpp-empty-test/CMakeLists.txt
diff --git a/tests/cpp-empty-test/CMakeLists.txt b/tests/cpp-empty-test/CMakeLists.txt
