Sorry for my rudimentary question.
Environment:
・Xcode 15.3
・C++
・Freeglut 3.4.0
・XQuartz 2.8.6_beta2 (already started)
Current status:
The following problems occurred at the time of upgrading from Xcode 14.2 to Xcode 15.3. Despite setting DISPLAY appropriately in the user environment variable, an error message " failed to open display '' " is thrown when RUN with Xcode. However, if I run the binary built with Xcode directly in the terminal, it works fine.
Question:
Why is the DISPLAY environment variable not being passed to Xcode internals properly when RUN in Xcode?
