Building and configuring

To build the example:

• You can build the example from your IDE or the command line.

  If you use an IDE, import the bld.inf file of the example into your IDE, and use the build command of the IDE.

  If you use the command line, open a command prompt, and set the current directory to the source code directory of the example. You can then build the example with the SBSv1 build tools with the following commands:

  bldmake bldfiles

  abld build

  How to use bldmake and How to use abld describe how to use the SBSv1 build tools.

• For the emulator, the example builds an executable called libmexample.exe in the epoc32\release\winscw\<udeb or urel>\ folder.

Running the example

Run the libmexample.exe executable. The example application waits for the user to enter an input value.
