a. Create a backup copy of the provided license file.
b. Save the new license file on your local hard drive.
c. Append the
<path_to_license_file>/<license_filename>
file to the LM_LICENSE_FILE environment
variable.
5. If you have a floating licence, append the
<path_to_license_file>/<license_filename>
file to the
LM_LICENSE_FILE environment variable in the following manner:
a. Obtain the port number and host name from the network or system administrator. Alternatively,
the information is in the license file line
SERVER <hostname> <8 to 12 character host or NIC
ID> <port>
.
The license location for the user is <port>@<hostname>. If a port is not listed in the license file,
specify @<hostname>.
b. Modify the license file to update the port number and host name.
c. Append the
<path_to_license_file>/<license_filename>
file to the LM_LICENSE_FILE environment
variable.

Recompiling the Linux Kernel Driver
Attention: If you download and install the Altera SDK for OpenCL, the Cyclone V SoC Development Kit
Reference Platform (
ALTERAOCLSDKROOT/board/c5soc
) includes an SD card image (
linux_sd_
card_image.tgz
) that contains the recompiled Linux kernel driver.
If you need to rebuild the Linux kernel driver, recompile the
aclsoc
Linux kernel driver to the exact version
of the Linux kernel running on the SoC.
Important: You must recompile the
aclsoc
Linux kernel driver on your Linux development machine.
1. Unpack the
aocl-rte-<version>.arm32.tgz
tarball to a temporary directory on your development machine
by typing the
tar -xvfz aocl-rte-<version>.arm32.tgz
command.
2. Navigate to the
ALTERAOCLSDKROOT/board/c5soc/driver
subdirectory of the unpacked
aclrte-arm32
package.
3. Perform the tasks outlined in the Recompiling the Linux Kernel and the OpenCL Linux Kernel Driver
section of the Altera Cyclone V SoC Development Kit Reference Platform Porting Guide.
