25 | Use the following commands to unarchive the gdb distribution: |
---|
26 | |
---|
27 | @example |
---|
28 | cd tools |
---|
29 | tar xzf ../archive/@value{GDBTAR} |
---|
30 | @end example |
---|
31 | |
---|
32 | The directory @value{GDBUNTAR} is created under the tools directory. |

62 | If any files are found with the .rej extension, a patch has been rejected. |
---|
63 | This should not happen with a good patch file. |
---|
64 | |
