Informative Report: "qcc license check failed"

Why "QCC"?

The acronym QCC usually refers to Qualcomm Code Configurator or Qualcomm’s internal license feature codes. However, the error structure has become generic. Many third-party vendors who build debugging probes for Qualcomm chips have adopted the same nomenclature. Therefore, "QCC" may refer to:

  • Qualcomm Core Tools: Used for modem debugging and RF testing.
  • Generic Compiler Licenses: A misnomer where "QCC" stands for "Quality Control Check."
  • Embedded IDE Plugins: Specific to IAR, Keil, or Eclipse environments.

Because "QCC" is ambiguous, your troubleshooting path depends on your industry.

Part 4: The Step-by-Step Troubleshooting Workflow

Follow this diagnostic flowchart exactly. It resolves 95% of "QCC License Check Failed" errors.

Linux (Ubuntu/CentOS)

  • Libstdc++ Issue: Older QCC tools need legacy libraries. Run sudo apt-get install libstdc++5 (Ubuntu) or yum install compat-libstdc++-33 (CentOS).
  • SELinux Block: Run sudo setenforce 0 to test. If the error disappears, create a policy for your license daemon.

Step 3: Check Environment Variables

  1. Open Command Prompt and type: set LM_LICENSE_FILE
  2. You should see something like 27000@my-server or C:\Licenses\qcc.lic.
  3. Red Flag: If you see multiple paths separated by semicolons, FlexNet will fail at the first dead path. Remove all but the primary path.
  4. Action: Set the variable specifically for QCC: set QCC_LICENSE_FILE=27000@localhost (or your actual server).

Why the Error Occurs

The "License Check Failed" message is essentially an authentication failure. The software asked for permission to proceed, and the system (or the server it is contacting) denied the request. Common causes include:

  1. Missing or Corrupt License Files: The specific .lic file or security certificate required by the tool is missing from the installation directory or has become corrupted.
  2. Expired License: Many professional developer licenses are subscription-based. If the license term has ended, the check will fail.
  3. Date and Time Misconfiguration: License checks often rely on system timestamps. If your computer’s date or time is incorrect, the software may think the license is invalid or expired.
  4. Server Connectivity Issues: Some tools perform an online "handshake" with a Qualcomm server to verify the license. If your internet connection is unstable or the server is down, the check will fail.
  5. Hardware ID Mismatch: Some licenses are bound to the specific Hardware ID (MAC address or Serial Number) of the computer. If you changed hardware components or moved the software to a new PC, the license will fail.
  6. Antivirus/Firewall Interference: Security software may block the tool from accessing the internet to validate the license or from reading the license file locally.

The "qcc license check failed" error typically occurs when the QNX compiler (qcc) cannot locate a valid license key or communicate with the license server. This is common in QNX Software Development Platform (SDP) environments. Common Solutions

Verify Environment Variables: Ensure your QNX_CONFIGURATION and QNX_HOST environment variables are correctly set. The compiler relies on these to find the license files.

Run the Configuration Script: On Linux or Windows, you often need to run the qnxsdp-env.sh (or .bat) script located in your SDP installation directory to properly set up the shell environment.

Check License Expiration: Log in to the QNX License Management portal to ensure your license hasn't expired or reached its seat limit.

Server Connectivity: If you are using a floating license, verify that your machine can reach the license server and that the license.dat file correctly points to the server's port and IP.

Support Forums: You can find specific discussions regarding this error on the QNX Community Forums, where developers often share environment-specific fixes for QCC license issues. QCC: license check failed - TeamForge : Post qcc license check failed

The "QCC license check failed" error is a common roadblock for developers and engineers working with Qualcomm’s proprietary toolsuites, such as the Qualcomm Hexagon SDK or various wireless connectivity stacks. At its core, this error indicates that the software cannot verify a valid entitlement to run the requested process. Common Root Causes

Missing or Expired License File: The most frequent culprit is simply the absence of a .lic file or an expired subscription. Qualcomm tools often look for a specific environment variable to locate these files.

MAC Address Mismatch: Many QCC licenses are "node-locked," meaning they are tied to the unique hardware ID (MAC address) of your machine. If you’ve switched computers, changed network cards, or are using a virtual machine with a dynamic MAC address, the check will fail.

Environment Variable Issues: Tools often rely on the ARMLMD_LICENSE_FILE or QCC_LICENSE_FILE variables. If these paths are incorrect or contain typos, the software will look in the wrong place.

Network/Server Connectivity: If you are using a "floating" or server-based license, your machine must be able to ping the license server. Firewalls or VPN changes often disrupt this connection. How to Fix It

1. Verify Environment VariablesCheck that your system environment variables point to the correct license file or server.

On Windows, search for "Edit the system environment variables."

On Linux/macOS, use echo $QCC_LICENSE_FILE in your terminal.Ensure the path is absolute and the file actually exists at that location.

2. Check the MAC AddressOpen your license file in a text editor. Look for a field labeled HOSTID. Compare this value to your computer’s physical address (found via ipconfig /all on Windows or ifconfig on Linux). If they don’t match, you will need to request a re-host from the Qualcomm CreatePoint portal.

3. Test the License ServerIf your license is hosted on a server: Ensure you are connected to the office network or VPN. Informative Report: "qcc license check failed" Why "QCC"

Check if the license manager (like FlexLM) is actually running on the server side.

Verify that the port (usually 27000-27009) isn't being blocked by your local firewall.

4. Update the SDK/ToolsSometimes, a local tool update breaks compatibility with older license formats. Ensure your Hexagon SDK or QCC build tools are compatible with the version of the license you were issued.

When you see "qcc license check failed," treat it as a pathing or identity problem. Start by confirming the software knows where to look (environment variables) and that your hardware matches who the license was intended for (MAC address). To help you troubleshoot this further, could you tell me:

Which Qualcomm tool or SDK (e.g., Hexagon, QCC51xx) are you using?

Are you using a node-locked file or a network/floating license? What Operating System are you running?

I can provide specific command-line steps once I have those details.
