Chapter 5: Inspect IOC application configuration

Follow the lessons in order; keep the application source for later exercises.

• Compare function-style and space-separated commands.
• Select dependency paths with RELEASE and local overrides.
• Change installation and IOC-visible paths.
• Run an operating-system command from the IOC shell.

Chapter exercises

1. Save any existing configure/RELEASE.local. Set EPICS_BASE to /nonexistent/epics/base in that file and run make. Restore the saved content, or set it to the active Base path, and rebuild.
2. Complete the command-style comparison in lesson 5.1 and the installation-path exercise in lesson 5.3.
3. Explain the difference between selecting dependencies in RELEASE and selecting build options in CONFIG_SITE.

Before moving on

• configure/RELEASE.local and configure/CONFIG_SITE.local in jeonglee_Demo/ are restored so make succeeds.
• iocBoot/ioctraining-jeonglee_Demo/envPaths sets TOP to your jeonglee_Demo directory, with db/ and iocsh/ intact for Chapter 6.
• Every jeonglee_Demo IOC, softIoc, and tc32_emulator.bash process is stopped.
• ss -ltn 'sport = :9399' reports no active TCP listener.
