Installing the SDKs

Which drive should I install my Software Development Kit on?

(Taken from Psion)

The Software Development Kit must be installed in the root directory of a drive - it is recommended that you create a clean drive using one of the methods below:

Use a substituted drive

Make a directory and use the subst command to map this to an unused drive letter. For example, to create a virtual drive with the letter e that corresponds to the path c:\erj, you would type the following command at the DOS command prompt:

subst e: c:\erj

The computer then teats this virtual (or mapped) drive as a completely separate physical drive. The benefit of this is that the emulator is self contained and is a better simulation of a separate device.

Note that the mapped drive and the original folder are one and the same: changing one changes the other.

However, every time you reboot, the mapped drive will not be accessible until you re-execute the subst command. To automate this insert the subst command in your autoexec.bat, or into the startup folder as follows: (Windows NT will not execute batch files in your autoexec.bat unless you include it in the startup folder).

  1. Create a .bat file and include the subst command in it (use an application like Notepad and save the file as ďall filesĒ but with a Bat extension)
  2. Click Start, and then point to Settings.
  3. Click Taskbar, and then click the Start Menu Programs tab.
  4. Click Add, and then click Browse.
  5. Locate the batch file you want to start, and then double-click it.
  6. Click Next, and then double-click the StartUp folder.
  7. Type the name that you want to see on the Startup menu, and then click Finish.
On Windows NT and Windows 95/98, the subst command makes the mapped drive visible to all programs immediately (though File Manager or Explorer will not update their available drive list immediately). Pressing F5 (View | Refresh) will make it visible.

Use shared drives

Note: This can be slower than the first method.

Make a directory, e.g. c:\erj\, select it in the NT4.0 Explorer and use the Sharing... option on the right-click menu to share.

Use Tools | Map Network Drive to connect to it. Or from File Manager use Disk | Share As, and then use Disk | Connect Network Drive to connect. Use the Reconnect at logon box to make the share permanent. This method allows you to share your work with others on the network. If you donít want to do this, set the share permissions appropriately.

Either of these approaches will allow you to maintain multiple EPOC Software Development Kits on different drives, and to switch between them on demand.

General help can be found in the Software Development Kits.


C++, Java™ and OPL

  1. The SDK will be downloaded as a zipped file (or files), so unzip it to a folder of choice, e.g. C:\PSION\EPOC

  2. When unzipped, install the program by running the file SETUP.EXE. The EPOC emulator will install to the default location, C:\EPOC32

  3. Read the readme.txt file. You may need to create a virtual drive to run the emulator. If you do you can add the following line to your AUTOEXEC.BAT file:


    (where F: is the name of the virtual drive, and C:\EPOC is the location of the Emulator. Alter these for your own computer setup).

    You can read about it here on the Symbian Tech Notes: Which drive should I install my Software Development Kit on?

  4. Tip: If you do not create a virtual drive you may find in My Computer that the default icon for Drive C has changed to the EPOC icon. In this case, you shall need to create a virtual drive to correct this.

    Drive F will now have the EPOC icon. You may find that if you double-click the F drive icon you are prompted to set-up Windows. To correct this right-click Drive F and select "Open" (or locate C:\EPOC32) and edit the file autorun.inf removing, or REMing the line OPEN=SETUP.EXE

  5. As this is simply the EPOC operating system running under Win32 you have no need for BAT files or rebooting to DOS. Simply choose which size screen you want to run and click the appropriate icon. The emulator will first open a DOS screen and then the main interface.
