CEF v138 Integration Issue: "Parse process unknown, exit" Error

CEF v138 Integration Issue: "Parse process unknown, exit" Error

Environment

• QCefView Version: Latest from main branch
• CEF Version: v138.0.36 (Chromium M138)
• Platform: Windows 64-bit
• Qt Version: Qt6.9.1
• Compiler: MSVC2022

Issue Description

I attempted to integrate CEF v138 with QCefView, but the application immediately terminates with the error message:

Parse process unknown, exit

Background

I understand that CEF v138 introduced significant architectural changes, specifically:

• Alloy bootstrap removal: The Alloy bootstrap was completely removed starting from CEF v138
• Chrome runtime only: CEF now operates exclusively with Chrome runtime
• API changes: Several CEF APIs that QCefView may depend on have been deprecated or removed

Questions

1. Compatibility Status: Is QCefView currently compatible with CEF v138 and later versions that use Chrome runtime exclusively?

2. Migration Plan: Are there any plans to update QCefView to support the new Chrome runtime-only architecture?

3. Workaround: Is there any configuration or code modification that could make QCefView work with CEF v138?

4. Recommended CEF Version: What is the latest CEF version that is known to work reliably with the current QCefView implementation?

Thank you for your time and for maintaining this excellent library!

I briefly looked into the M138 version, and as you mentioned, it introduces significant architectural changes. Unfortunately, I don’t have time to work on adapting to the new version at the moment. That said, I’m hoping to revisit this later in the year and plan for proper integration when my schedule allows. Thanks for your understanding.
