Firstly we just read and follow the instructions contain in the Build Notes doc (we recap here):
This is a description for Delphi newbies of the basic steps involved in compiling the FreeOTFE GUI.
To build the GUI, the following software is required:
The binary release of this software was built with Delphi v7, but you should well be able to use any version later than this.
§ Build each package
§ Install each package
§ Ensure that the correct path to each package is added to your Delphi environment ("Tools | Environment Options...", "Library" tab)
You have now successfully built the GUI frontend!
If required, the compiler definition "FREEOTFE_TIME_CDB_DUMP" may be set, in which case the time takes to dump a CDB ("Tools | Critical data block | Dump to human readable file...") will be shown after the dump completes.
We use Delphi for Microsoft Win32 (It will generate the exe file for each package. If using the .NET version, the whole project will be converted to the .NET version and each package will be in.dll and do expect more warnings and errors! So let be safe by using compiler that ‘close’ to the original compiler used)

Next we open the SDeanComponents project.

Following the steps from theBuild Notes, we build every package one by one. Keep in mind that you will encounter many warnings because our project environment settings are based on the default set. However, in this purpose we just want to see the working GUI, so warnings can be ignored at this stage.
If there are error(s) we need to correct them first else we could not run the program. The following is the build and install steps. You can select Install (Select a package and right click and select the Install menu) menu for each package directly because Install step contains Build step. That mean when you choose theInstall menu, it will Build first and then Install (register the components/packages to the Delphi project environment that we will see later). We found a lot of warning but without a single error. That is a good sign that we can test the GUI using the demo main program.

The following are warnings examples generated when we Build a package. It seems that some package built without any warning and error. Default Delphi project setting will terminate the Build process if there are error(s). Just proceed to the Build and Install each package, ignoring those warnings.
Figure 7: Component building warning messages seen through Messages window
The following figure shows theInstall step of each package. There will be message dialog box displayed for each successful or failed Installed package as shown below.
Figure 8: Failed to install the component or package message box
Figure 9: Successfully install the component or package message box
We successfully Build and Install each package without a single error but with a lot of warnings :-).
Figure 10: Invoking the Install menu to install the package or component
Next, let check whether our packages/components have been installed properly by choosing Project→Options… menu.
Figure 11: Opening the project’s options page by invoking the Options… menu
Select the Packages folder and scroll down. You can see that those built and installed packages have been registered. Others are default packages that registered by default when we choose Delphi Win32 project.

Finally save all the project components.

Before we build the sdDemo main program, optionally we can check the syntax by using the following menu. Any error(s) will be detected at in this step.
Figure 14: Checking all the sdDemo project syntax
Next we build the demo program by choosing the following menu. This demo program will display the main GUI of the FreeOTFE.
Figure 15: Building the sdDemo program
Fortunately we only have one warning and one hint. The deprecated symbol need to be replaced with new symbol version that normally available in new edition of the Borland Delphi. So if we need to correct this, we need to read Borland Developer Studio 2006 manual/help file. However in this case, just forget it; we are not building this program for Release version! However if there are error(s) we need to correct it first else we can’t run the program.
Figure 16: A warning and hint seen in the Messages windows
Provided that there is no single error in the previous step, we are ready to run the main program (with all the related and needed packages/components have been registered). So, selectRun → Run Without Debugging menu shown below.
Figure 17: Running the program without debugging
Well, the following error message dialog box displayed. It is normal because we just running the GUI, the driver is not installed (this is the next stage after successfully build the GUI, using Microsoft Visual C++ compiler). Just click the OK button.

Save All and Close All the previous project.
