最近在研究cocos2d-x，下載下來之後，要在ubuntu上跑起來費了一番功夫。總結以下：
1、下載代碼
$ git clone [email protected]:cocos2d/cocos2d-x.git
2、搭建環境
$ cd cocos2d-x/build
$ ./install-deps-linux.sh
3、安裝cmake版本和gcc g++版本
要求：
cmake版本：2.8.0
gcc g++版本：4.8.1
4、編譯
$ cmake ..
$ make
cmake的時候，ubuntu 10.04很可能遇見如下錯誤：
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):
include could not find load file:
/FindPackageHandleStandardArgs.cmake
...
第二個錯誤中：glew相關的包都已經安裝了。
我從android的代碼下找了一個FindGLEW.cmake文件，放到了cmake/Modules下面
其他兩個錯誤，我是這樣改的：

修改之後cmake不報錯，make的時候報錯，編譯glfw報錯：
看報錯的信息應該是glfw的版本不對，要去glfw3，但是我電腦上是glfw2
但是apt-get無法安裝glfw3，許是ubuntu版本不夠高，於是我到glfw.org網站上下了一份glfw3的源代碼，然後自己編譯。
http://www.glfw.org/docs/latest/compile.html#compile_cmake
然後編譯還會報如下錯誤：
../../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'

這時應該把本地的glfw2版本完全刪除。：
sudo apt-get remove XXX
這還沒完，編譯到cpp-empty-test的時候，還會報錯：
Linking CXX executable ../../bin/cpp-empty-test/cpp-empty-test
/bin/sh: cannot create /Resources: Permission denied
make[2]: *** [bin/cpp-empty-test/cpp-empty-test] 錯誤 2
make[1]: *** [tests/cpp-empty-test/CMakeFiles/cpp-empty-test.dir/all] 錯誤 2
make: *** [all] 錯誤 2
需要修改如下：
