The OS source code can also be obtained from either a tarball or zip file. This may be preferred for users who are not managing other COIN-OR projects and wish to only work with periodic release versions of the code. In order to obtain the code from a Tarball or Zip file do the following.
Step 1: In a browser open the link http://www.coin-or.org/Tarballs/OS/. Listed at this page are files in the format:
OS-release_number.tgz OS-release_number.zip
Step 2: Click on either the tgz or zip file and download to the desired directory.
Step 3: Unpack the files. For tgz do the following at the command line:
gunzip OS-release_number.tgz tar -xvf OS-release_number.tar
Windows users should be able to double click on the file OS-releaseFnumber.zip and have the directory unpacked.
Step 4: Rename OS-releaseFnumber to COIN-OS.
Now build the project as described in Section 4.
