I found that in Eclipse CDT 4.5.2 (8.8) in the class org.eclipse.cdt.dsf.gdb.launching.LaunchUtils
there was a constant MACOS_GDB_MARKER
that no longer exists in eclipse CDT 4.6.3 (9.2.1). I want to know why. Is there no more difference between GDB for MacOS and others ? Is GDB for MacOs no more supported ? Is the constant "hidden" in another class ?
I found out the answer. As explain here and there, The specific GDB produced by Apple is no more updated by Apple. So the CDT team decided to remove its support from CDT.
