  1. INTRODUCTION
  2. ============
  3. ucore labs was used as OS Experiments in OS Course Of Dept. of Computer Science & Technology, Tsinghua University.
  4. ucore is a teaching OS which is derived from xv6&jos in MIT, OS161 in Harvard and Linux.
  5. ucore was developed and used in Department of Computer Science & Technology, Institute for Interdisciplinary Information Sciences, Tsinghua University.

  34. WORK IN MS WINDOWS
  35. ==================
  36. Working in Linux is encouraged. But If you like to work in MS Windows, we provide virtual machine environment (Runnint Ubuntu in VirtualBox) in
  37. Windows to help you to finish the labs. If you don't want to install ubuntu and other softs to finish these labs in Windows, you can use
  38. VirtualBox soft (https://www.virtualbox.org/) and a virtual disk image with all these softs. Below example is shown how to setup lab environment in Windows.
  39. You can download this virtual disk image -- oslabs_for_student_2012.zip (576.2MB,) from http://pan.baidu.com/share/link?shareid=69868&uk=2585194235, which
  40. is an VirtualBox disk image (contains ubuntu 12.04 and needed softs, and is zipped with zip and xz format), and can be unzipped
  41. by haozip software (http://www.haozip.com).
  42. After unzip oslabs_for_student_XXX.zip, you will get
  43. ---
  44. C:\vms\ubuntu-14.04.vbox.xz
  45. C:\vms\ubuntu-14.04.vmdk.vmdk.xz
  46. C:\vms\ubuntu-14.04.vmdk-flat.vmdk.xz
  47. ---
  48. then you will continue unzip all these files, and get
  49. ---
  50. C:\vms\ubuntu-14.04.vbox
  51. C:\vms\ubuntu-14.04.vmdk.vmdk
  52. C:\vms\ubuntu-14.04.vmdk-flat.vmdk
  53. ---
  54. If you installed VirtualBox soft, then the last step is: double clik file "ubuntu-12.04.vbox" and run ubuntu 12.04 in VirtualBox.
  55. In ubuntu 12.04 login Interface:
  56. username: chy
  57. password: <SPACE KEY>
  58. After you login, you will see the directory ucore_lab in HOME directory.
  59. TESTED ENVIRONMENT
  60. ==================
  61. UBUNTU 14.04: GCC-4.8.2 CLANG-3.5
  62. FEDORA 20: GCC-4.8.2
  63. EXERCISE STEPS
  64. ==============
  65. 0 Get the newest os lab src codes/docs.(Insure you can connect to github in ubuntu running on VrtualBox)
  66. 0.1 If you try to get all codes
  67. $rm -rf ucore_lab
  68. $git clone git://github.com/chyyuu/ucore_lab.git
  69. $cd ucore_lab
  70. 0.2 If you gloned ucore_lab and only try to get the updated codes
  71. $cd ucore_lab
  72. $git pull
  73. 1 $cd labX
  74. 2 read codes (specially the modified or added files)
  75. 3 add your code
  76. 4 compile your code
  77. $make
  78. 5 check your code
  79. $make qemu
  80. OR
  81. $make grade
  82. 6 debug your code
  83. $make debug
  84. 7 handin your code
  85. $make handin
  86. OPTION
  87. ==============
  88. Now, ucore suuport LLVM/Clang-3.5 +
  89. in step4:
  90. $ USELLVM=1 make
  91. then you will use clang to compile ucore
  92. GRADE/RANK
  93. ==========
