Resolving CTP Version Mismatches on macOS

Summary

This post describes a macOS setup problem connecting VeighNa’s CTP interface to a futures broker. The reported symptoms are an initial 4040 error followed by repeated 4097 errors. The author says the broker’s troubleshooting materials targeted Windows, while their macOS setup required framework files rather than DLLs.

The suggested remedy is to obtain the macOS build of the broker’s through-market supervision package, replace two framework files in the project’s CTP API directory, and update the package version in the project configuration before rebuilding and installing it. The author also tried placing the macOS collection framework alongside the other files, though they were unsure whether that step mattered. They report that the connection succeeded afterward, but provide no independent diagnosis, detailed test results, or confirmation that the procedure works across broker versions and environments.

Key ideas

• Repeated CTP connection errors may be associated with a mismatch between broker-provided files and a macOS setup.
• The post recommends using macOS framework files in place of Windows DLL-based materials.
• The project version setting must match the framework version before rebuilding the package.
• The author reports a successful connection after applying the changes, but gives no broader validation.
