Uninstalling the Software

To uninstall the RTE for Linux, remove the software package via the Red Hat Package Manager (RPM) or

GUI uninstaller, then delete the software directory and restore all modified environment variables to their

previous settings.

1. Remove the software package by performing one of the following tasks:

To uninstall the RTE via RPM at the command line, type the rpm -e aocl-rte command.

b. Delete the aclrte-linux64 directory.

2. Remove $ALTERAOCLSDKROOT/bin from the PATH environment variable.

3. Remove $ALTERAOCLSDKROOT/host/linux64/lib from the LD_LIBRARY_PATH environment variable.

4. Remove the ALTERAOCLSDKROOT environment variable.

Uninstalling the FPGA Board

To uninstall an FPGA board for Linux, invoke the uninstall utility command, uninstall the Custom

Platform, and unset the relevant environment variables. You must uninstall the existing FPGA board if

you migrate your OpenCL application to another FPGA board from a different Custom Platform.

To uninstall your FPGA board, perform the following tasks:

1. Following your board vendor's instructions to disconnect the board from your machine.

Invoke the aocl uninstall utility command to remove the current host computer drivers (for

example, PCI Express (PCIe) drivers). The RTE uses these drivers to communicate with the FPGA

board.

3. Uninstall the Custom Platform.

4. Unset the LD_LIBRARY_PATH environment variable.

5. Unset the AOCL_BOARD_PACKAGE_ROOT environment variable.
