Adding ns-2 to a CVS Repository


The goal is to place an ns-2 source tree (not executables, object files, etc.) into a CVS repository. By excluding the non-source files, the branch only uses about 28 MB of space in the repository. This assumes TCL, Perl, and all other programs included in the ns all-in-one distributions is already installed on the machine on which the ns-2 source tree will be checked out.

  • Setting Up the Repository
    1. Download an ns-2 source tree.
    2. We assume the source files are unzipped into the directory:
    3. Remove the tcl validation test files from the source tree (these take up a lot of space and are not used outside of validating the code):
      cd ~/ns-src/tcl/;
      rm -rf test;
    4. Import the remaining source files into the repository:
      cd ~/ns-src/;
      cvs import ns_proj ns_manufacturer initial;

  • Checking Out and Compiling ns-2
    1. Checkout the source tree on your local machine (this may take a few minutes with a high speed connection):
      cvs co ns_proj
    2. Now, run the configure script and specify the location of you otcl and tclcl installations (assume they are in /usr/local/):
      cd ns_proj;
      ./configure --with-otcl=/usr/local/otcl-1.0a8 --with-tclcl=/usr/local/tclcl-1.0b12;
    3. If successful, a Makefile was generated, specific to your local machine. Run make to compile ns-2:
    4. Now, when CVS commit is done, only files from the original source tree, not executables and object files, will be updated in the repository. If you delete the ns_proj directory (either with rm or the -d switch for the cvs release command), you will have to repeat Step 2 when checking the project out again. Otherwise, you should be able to check the ns source distribution out without doing the configure command again.
    5. Before importing the source tree, you may want to delete files local to your machine. Specifically, the files created by configure (e.g., a few Makefile's) and the files in the gen/ directory since these are specific to your machine.
