### Building for VxWorks

The build_vxworks directory in the Berkeley DB distribution contains a workspace and project files for Tornado 2.0/VxWorks 5.4 and Tornado 2.2/VxWorks 5.5.

File | Description
--- | ---
BerkeleyDB20.wsp | Berkeley DB Workspace file for Tornado 2.0
BerkeleyDB20.wpj | Berkeley DB Project file for Tornado 2.0
BerkeleyDB22.wsp | Berkeley DB Workspace file for Tornado 2.2
BerkeleyDB22.wpj | Berkeley DB Project file for Tornado 2.2
dbdemo/dbdemo20.wpj | Demo program project file for Tornado 2.0
dbdemo/dbdemo22.wpj | Demo program project file for Tornado 2.2
db_*/*20.wpj | Support utilities project files for Tornado 2.0
db_*/*22.wpj | Support utilities project files for Tornado 2.2

### Building With Tornado 2.0 or Tornado 2.2

Open the workspace BerkeleyDB20.wsp or BerkeleyDB22.wsp. The list of projects in this workspace will be shown. These projects were created for the x86 BSP for VxWorks.

The remainder of this document assumes that you already have a VxWorks target and a target server, both up and running. It also assumes that your VxWorks image is configured properly for your needs. It also assumes that you have an acceptable file system already available. See VxWorks FAQ for more information about file system requirements. See VxWorks Notes for more information about building a small footprint version of Berkeley DB.

First, you need to set the include directories. To do this, go to the Builds tab for the workspace. Open up Berkeley DB Builds. You will see several different builds, containing different configurations. All of the projects in the Berkeley DB workspace are created to be downloadable applications.

Build | Description
--- | ---
PENTIUM_debug | x86 BSP with debugging
PENTIUM_release | x86 BSP no debugging

You have to add a new build specification if you use a different BSP, want to add a build for the simulator or want to customize further. For instance, if you have the Power PC (PPC) BSP, you need to add a new build for the PPC tool chain. To do so, select the "Builds" tab, select the Berkeley DB project name, and right-click. Choose the New Build... selection and create the new build target. For your new build target, you need to decide whether it should be built for debugging. See the properties of the Pentium builds for ways to configure for each case. After you add this build you, you still need to configure correctly the include directories, as described in the sections that follow.

If you are running with a different BSP, you should remove the build specifications that do not apply to your hardware. We recommend that you do this after you configure any new build specifications first. The Tornado tools will get confused if you have a PENTIUMgnu build specification for a PPC BSP, for instance.

Select the build you are interested in, and right-click. Choose the Properties... selection. At this point, a tabbed dialog should appear. In this new window, choose the C/C++ compiler tab. In the edit box, you need to modify the full pathname of the build_vxworks subdirectory of Berkeley DB, followed by the full pathname of Berkeley DB. Then, click OK. Note that some versions of Tornado (such as the version for Windows) do not correctly handle relative pathnames in the include paths.

To build and download the Berkeley DB downloadable application for the first time requires several steps:

1. Select the build you are interested in, and right-click. Choose the Set... as Active Build selection.

2. Select the build you are interested in, and right-click. Choose the Dependencies... selection. Run dependencies over all files in the Berkeley DB project.

3. Select the build you are interested in, and right-click. Choose the Rebuild All (Berkeley DB.out) selection.

4. Select the Berkeley DB project name, and right-click. Choose the Download "Berkeley DB.out" selection.

Note that the output file listed about will really be listed as BerkeleyDB20.out or BerkeleyDB22.out depending on which version of Tornado you are running. You need to repeat this procedure for all builds you are interested in building, as well as for all of the utility project builds you want to run.
