The error message you’re encountering, Makefile:44: *** "Please define RTE_SDK environment variable". Stop., indicates that the Makefile you are trying to use requires an environment variable called RTE_SDK to be set before it can proceed with the build process. This is common in projects that depend on specific SDKs (Software Development Kits) or libraries.
Here’s how you can resolve this issue:
Steps to Fix
Locate the SDK: First, determine where the required SDK (likely DPDK if it’s related to networking) is installed on your system.
Set the Environment Variable: You need to set the
RTE_SDKenvironment variable to point to the directory of the SDK. You can do this in your terminal:
For Linux/Mac:
export RTE_SDK=/path/to/your/rte_sdk
For Windows (Command Prompt):
set RTE_SDK=C:\path\to\your\rte_sdk
For Windows (PowerShell):
$env:RTE_SDK="C:\path\to\your\rte_sdk"
- Verify the Setting: After setting the variable, you can verify it by running:
For Linux/Mac:
echo $RTE_SDK
For Windows Command Prompt:
echo %RTE_SDK%
- Re-run Make:
Once you have set the
RTE_SDKvariable, try runningmakeagain in your project directory.
Additional Notes
- Ensure that you have actually installed the SDK and it contains all necessary files.
- If you’re using a shell configuration file like
.bashrc,.bash_profile, or.zshrc, you may want to add the export line there for persistent usage across terminal sessions.
If you continue to experience issues after this, make sure that you’ve correctly followed any additional setup instructions provided with your project or SDK documentation.
