Qcc License Check Failed
Check if QNX_LICENSE or LM_LICENSE_FILE environment variables point to the correct server:
export QNX_LICENSE=port@license_server_hostname
Test connectivity to the license server:
lmstat -a -c $QNX_LICENSE
The "QCC License Check Failed" error is almost never a hardware failure or a permanent lockout—it is almost always a configuration mismatch. By systematically checking your clock, environment variables, firewall rules, and service status, you will identify the culprit within 15 minutes.
Remember the golden rule of FlexNet licensing: The server grants, the firewall permits, and the environment directs. If all three align, your QCC tool will launch without a hitch.
If you have tried all the steps above and still see the error, your next stop is your vendor's support portal. Provide them your lmutil lmstat -a output and the debug log. Do not ask for a "new license" immediately; ask them to verify the feature code for your specific version. Often, the failure is just a typo on their side.
Now, go fix that license and get back to work.
The "qcc license check failed" error is a common issue encountered by developers using the QNX Software Development Platform (SDP). It typically occurs when the qcc compiler—part of the QNX Software Systems toolchain—cannot locate or validate a valid license on the host machine. Common Causes
Missing or Incorrect Environment Variables: The qcc tool relies on specific environment variables, particularly QNX_CONFIGURATION, to find license files. If these are unset or point to the wrong directory, the check will fail.
File Permission Restrictions: In modern operating systems like Windows 10/11, stricter security can prevent the compiler from reading the QNX Software Systems folder, even when run as an administrator.
Expired or Unactivated Licenses: The error often appears if a 30-day evaluation license has expired, if the license has been reassigned to another machine, or if the initial activation was never completed.
Registry/Configuration Mismatch: Using multiple versions of QNX tools (e.g., mixing version 6.x and 7.x) can lead to global variable conflicts that disrupt license validation for specific tools. Troubleshooting and Solutions 1. Verify Environment Variables
Ensure your system knows where to look for the license data. Check Variables: Open a console and run env | grep -i qnx.
Target Path: QNX_CONFIGURATION should point directly to your .qnx folder where licenses are stored.
Temporary Scripts: If you work across different versions, create a .bat or shell script to set these variables locally before running qcc rather than relying on global system variables. 2. Resolve Folder Access Issues If permissions are blocking the check:
Move the Folder: Relocate the "QNX Software Systems" folder to a directory where your user account has full read/write access.
Update Path: Change the QNX_CONFIGURATION environment variable to point to this new location.
Reactivate: Run qnxactivate.exe from the new location to re-establish the license link. 3. Complete Registration and Activation
EULA Acceptance: Ensure you have logged into the QNX website and accepted the End User License Agreement (EULA). Failure to do so can leave your account in an "incomplete registration" state.
Check Software Center: Open the QNX Software Center to verify the current status of your seats and serial numbers. If you have exceeded your activation limit, you may need to contact corp-activate@qnx.com for a reset. 4. Network and Floating License Issues
If your organization uses a floating license server (FlexNet):
Ensure your network adapter matches the one used during initial licensing; switching from Ethernet to a VPN or Wi-Fi can sometimes break the "heartbeat" to the server.
Verify that your firewall is not blocking TCP port 27000 or other ports required by the license daemon. Debugging Floating License (flexnet ... - Knowledge Base qcc license check failed
The "qcc license check failed" error typically occurs when the QNX C/C++ compiler (qcc) cannot locate or verify a valid license key on your development host. This prevents building or compiling applications within the QNX Software Development Platform (SDP). Common Causes
Missing or Incorrect Environment Variables: The compiler relies on $QNX_CONFIGURATION to find the license folder (usually .qnx). If this variable is missing or points to the wrong location, the check will fail.
Activation Issues: The license might be present but not properly activated on the local machine.
Expired or Invalid License: The license key may have expired, or your account registration with the QNX website might be incomplete.
Permissions: On Windows 10/11, the compiler may lack read/write access to the "QNX Software Systems" folder, especially if it was installed with admin rights but is being run as a standard user. Troubleshooting Steps
Verify Environment Variables: Ensure $QNX_CONFIGURATION is correctly set. You can check this by running env | grep -i qnx in your console.
Move License Folder (Windows Fix): If you have permission errors, move your "QNX Software Systems" folder to a location where you have full read/write access and update your $QNX_CONFIGURATION variable to point there.
Check License Status: Open the QNX Software Center and navigate to the Licenses tab. Right-click your product to check its properties and ensure the status is "Activated".
Reactivate the License: If the local record is corrupted, try deactivating and then reactivating the license via the qlicense utility or Software Center.
Complete Registration: Log into the QNX official site and ensure you have agreed to the latest End User License Agreement (EULA).

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.
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.
Modern security software hates license daemons. Windows Defender, McAfee, or corporate firewalls often quarantine lmgrd.exe (the license manager daemon) or block ports 27000-27009. The license server thinks it is sending a "Grant," but the firewall eats the packet.
(If you want, I can produce a diagnostic command list tailored to Linux, Windows, or macOS — tell me which OS.) The "QCC License Check Failed" error is almost
The error message "qcc license check failed" typically occurs within the QNX Software Development Platform (SDP) environment when the compiler (qcc) is unable to verify a valid development license. This issue can halt the build process for embedded systems and real-time operating systems (RTOS) like those used in automotive or industrial applications. Common Causes of QCC License Failure
Expired Evaluation License: Standard QNX 30-day evaluation licenses automatically expire, preventing further use of the qcc compiler.
Missing Environment Variables: The system might not know where to find your license file if the QNX_CONFIGURATION or QNX_HOST paths are incorrectly set.
Lockfile Conflicts: A specific file, /etc/qnxlicenses.lck, might be locked by another process or lack the necessary write permissions for the current user.
Network or Firewall Issues: For floating licenses, the client machine must be able to reach the license server. Firewalls can block necessary ports (like FlexNet ports), or the license server service might be down.
Hardware Changes: Significant hardware upgrades (like a new motherboard or MAC address) can invalidate a node-locked license because the machine's unique Hardware ID no longer matches the one registered with QNX. How to Fix "qcc license check failed"
Verify Your License ActivationCheck if your license is still active by logging into the QNX License Management portal. If you are using a professional license, ensure the "development seat" is correctly assigned to your current host ID.
Clear Lockfiles (Linux/QNX Hosts)If the error mentions a "Lockfile acquisition timed out," navigate to /etc/ and check for qnxlicenses.lck.
Ensure your user has write permissions for the /etc/ folder.
If no other build processes are running, try deleting the .lck file and restarting your build.
Correct Pathing and Environment VariablesEnsure your shell is properly initialized for QNX development. Running the provided qnxsdp-env.sh (Linux) or qnxsdp-env.bat (Windows) script sets critical variables like QNX_HOST and QNX_TARGET, which qcc uses to locate license certificates.
Re-activate Your License KeyFor node-locked setups, you may need to remove the local cache and re-enter your license key.
Linux: Check your home directory for hidden license files (e.g., .qt-license or QNX-specific equivalents) and move them to a backup location before re-running the activation tool.
Windows: Check %LOCALAPPDATA% for application-specific license folders and clear the cached .key files.
Troubleshoot Floating License ServersIf your organization uses a license server:
Verify the FlexNet Publisher (formerly Flexera) service is running on the server.
Confirm your machine can "ping" the server and that ports (typically 27000–27009) are open.
Are you using a node-locked or floating license for your QNX environment? QCC: license check failed - TeamForge : Post
When encountering a "QCC license check failed" error, it typically indicates an issue with the licensing or configuration of the Qualcomm Chipset Compatibility (QCC) or a similar system on your device. This error might occur in various contexts, such as during a software update, while running a specific application, or when trying to access certain features on your device. Here are some general troubleshooting steps you can try to resolve the issue:
License daemons often need to write logs to C:\ProgramData or /var/log. If you run the software as a standard user and the daemon was installed by an admin, the check may fail silently.
This is the #1 cause. If your license server is a physical USB dongle (Sentinel HASP) or a network service, and that service isn't running, the check fails instantly. Symptoms: The error appears immediately upon launch.
Renew your license and update the license file.
