Hi, all,
I try to use 'M-x gdb' on Mac with tramp. But it runs into varies errors.
Here are some details:
Environment:
emacs 25.1.1 runs on Mac with tramp 2.2.13.25.1. And I have a test project
on a raspberry pi directory: /home/xxx/project/test_gdb/. It has a simple
file: test.c. test.c is compiled by gcc with -O0 -g to test_bin.
test.c:
1 int foo(int a, int b) {
2 int c = a + b;
3 return c;
4 }
5
6 int main(void) {
7 return foo(3, 4);
8 }
Steps:
1. Open test.c on raspberry pi in emacs
2. run 'M-x gdb' gdb -i=mi test_bin and open gdb-many-window mode.
3. In *gud-test* buffer, run: break 7
Then I get an error in emacs Message:
File
/scp:xxx@my-rasp-pi:/home/xxx/project/test_gdb/"/home/xxx/project/test_gdb/test.c"
no longer exists!
And in *gud-test* buffer, it prints following:
=== gud-test content start ===
96 Breakpoint 1 at 0x103c4: file test.c, line 7.
97 (gdb) list test.c:1
98 1 int foo(int a, int b) {
99 2 int c = a + b;
100 3 return c;
101 4 }
102 5
103 6 int main(void) {
104 7 return foo(3, 4);
105 8 }
=== gud-test content end ===
line 96 is OK, but I don't know why it prints line 97 to 105. I have not
typed any 'list' command. And it has set a break point on line 7.
4. I continue to run some debug command like: continue, but *gud-test*
buffer stucks until I type "Ctrl+g".
I don't know which part causes such error, gud-mode, tramp-mode or
something else and how to fix it.
Thanks for any suggestion!
