@chapter Building the Sample Application
@section Unpack the Sample Application
Use the following command to unarchive the sample application:
@example
cd tools
tar xzf ../archive/hello_world_c.tgz
@end example
@section Set the Environment Variable RTEMS_MAKEFILE_PATH
It must point to the appropriate directory containing RTEMS build for our
target and board support package combination.
@example
export RTEMS_MAKEFILE_PATH = \
<INSTALLATION_POINT>/rtems/<BOARD_SUPPORT_PACKAGE>
@end example
Where <INSTALLATION_POINT> and <BOARD_SUPPORT_PACKAGE> are those used when
configuring and installing RTEMS.
@section Build the Sample Application
Use the following command to start the build of the sample application:
@example
cd tools/hello_world_c
gmake
@end example
If no errors are detected during the sample application build, it is
reasonable to assume that the build of the GNU C/C++ Cross Compiler Tools
for RTEMS and RTEMS itself for the selected host and target
combination was done properly.
@section Application Executable
If the sample application has successfully been build, then the application
executable is placed in the following directory:
@example
tools/hello_world_c/o-<BOARD_SUPPORT_PACKAGE>/<filename>.exe
@end example
How this executable is downloaded to the target board is very dependent
on the BOARD_SUPPORT_PACKAGE selected.
