Mac Silicon Alire Run Fails Due to duplicate LC_RPATH

by

Summary

The alr run command fails for an Alire project based on GTKAda on Mac Silicon OSX 26.2 with XCode 26.2, despite a successful compile and build. The error message indicates a duplicate LC_RPATH issue.

Root Cause

The root cause of this issue is:

  • Duplicate LC_RPATH entries in the executable file
  • Incorrect configuration of the Alire toolchain
  • Incompatibility between the toolchain and the Mac Silicon architecture

Why This Happens in Real Systems

This issue occurs in real systems due to:

  • Misconfiguration of the development environment
  • Inconsistent toolchain settings
  • Lack of support for the Mac Silicon architecture in the toolchain

Real-World Impact

The real-world impact of this issue includes:

  • Failed execution of the program
  • Inability to test and debug the application
  • Delayed development and deployment of the project

Example or Code (if necessary and relevant)

-- No specific code is required to demonstrate this issue
-- The problem is related to the toolchain configuration and LC_RPATH entries

How Senior Engineers Fix It

Senior engineers fix this issue by:

  • Verifying the toolchain configuration and ensuring it is compatible with the Mac Silicon architecture
  • Removing duplicate LC_RPATH entries from the executable file
  • Updating the Alire configuration to use the correct toolchain settings

Why Juniors Miss It

Junior engineers may miss this issue due to:

  • Lack of experience with the Alire toolchain and Mac Silicon architecture
  • Insufficient understanding of the LC_RPATH concept and its implications
  • Inadequate testing and debugging of the application
