From: Tim Marston <tim <at> ed.am> To: bug-gnu-emacs <at> gnu.org Subject: 24.5; Breakpoints don't show in GDB over TRAMP Date: Tue, 24 May 2016 09:35:25 +0100
Hi, I've noticed that breakpoints don't show up in the source code when running GDB over TRAMP. It's quite reproducible. Steps to reproduce: 1/ run emacs $ emacs -q 2/ visit a some remote source code C-x C-f /laptop:/home/edam/src/lang/c++/hello-world/hw.cc 3/ run GDB M-x gdb RET RET 4/ switch back to source code window C-x b RET 5/ add breakpoint C-x C-a C-b What happens: The breakpoint doesn't show up in the source code buffer. When you run the program, the breakpoint still works. And when the program "breaks out", you get a current line indicator, showing you where execution is at. But no breakpoint. If you do the same as above, but with a local file (i.e., not via TRAMP), breakpoints show up as expected. Another detail, which may be related, is that if I try to set another breakpoint on the same line, I get this message: File /scp:laptop:/home/edam/src/lang/c++/hello-world/"/home/edam/data/dev/lang/c++/hello-world/hw.cc" no longer exists! Which would seem to indicate that emacs is becoming confused about file file names over TRAMP.
