Altera RTE for OpenCL - Manual (Page 23)

Setting the Environment Variables on Big-Endian Systems
You have the option to apply environment variables permanently or transiently. The environment
variable settings describe the FPGA board and the host runtime to the software.
Before you begin
Attention: If you install the software on a system that does not contain any C Shell Run Commands file
( .cshrc ) or Bash Run Commands file ( .bashrc ) in your directory, you must set the environment
variables ALTERAOCLSDKROOT and PATH manually. Alternatively, you may create
the .cshrc and .bashrc files, and then append the environment variables to them. To ensure that
the updates take effect, restart your terminal after you set the environment variables.
Attention: If you set the environment variables permanently, you apply the settings once during installa‐
tion. If you set the environment variables transiently, you must apply the settings during
installation and during every subsequent session you run.
• To apply permanent environment variable settings, manually include the following paths to the
corresponding environment variables:
Environment Variable Path to Include
PATH
$ALTERAOCLSDKROOT/bin
where ALTERAOCLSDKROOT points to the path of the software installa‐
tion
LD_LIBRARY_PATH $ALTERAOCLSDKROOT/host/ppc64/lib
$AOCL_BOARD_PACKAGE_ROOT/ppc64/lib
whereAOCL_BOARD_PACKAGE_ROOT points to the path of the Custom
or Reference Platform
• To apply transient environment variable settings, open a command window and run the
source
$ALTERAOCLSDKROOT/init_opencl.sh
command.
Example script output:
AOCL_BOARD_PACKAGE_ROOT path is not set in environment
Setting to default s5_ref board.
If you want to target another board, do
set AOCL_BOARD_PACKAGE_ROOT=board_pkg_dir
Adding $ALTERAOCLSDKROOT/bin to PATH
Adding $ALTERAOCLSDKROOT/host/ppc64/lib to LD_LIBRARY_PATH
Adding $AOCL_BOARD_PACKAGE_ROOT/ppc64/lib to LD_LIBRARY_PATH
Verifying the RTE Installation
Invoke the
version
utility command and verify that the correct version of the AOCL is installed.
