Failed — Qcc License Check
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
QCC License Check Failed: A Report
Ensure your user has write permissions for the /etc/ folder.
Conclusion
6. User Permission Errors (Non-Admin Mode)
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.
Informative Report: "qcc license check failed"
1. Executive Summary
The error message “qcc license check failed” typically appears in engineering and simulation software environments, most notably within ANSYS products (such as ANSYS Fluent, Mechanical, or CFX) or other high-performance computing (HPC) applications that rely on license management systems. The error indicates that the software’s license validation process—specifically for the qcc (likely a low-level licensing or queue/communication component)—has been unsuccessful, preventing the software from running.
- Handshake: The software sends a request to a license server (either locally on your PC or across the network).
- Authentication: The server checks a license file (usually
.lic) for your hostname, MAC address, or username.
- Count Check: The server verifies you haven’t exceeded the number of allowed concurrent users.
- Response: If steps 2 & 3 pass, the software runs. If not, you get "QCC license check failed."
7. Software Version Mismatch
You are using QCC Tool v4.5, but your license file only supports up to v4.2. The feature codes change between versions. The error message is misleading; it isn't a broken license, but an incompatible one.
