When qemu is compiled without debug, the dump gdb python script can fail with:
|
|
|
5d360b |
|
|
|
5d360b |
Error occurred in Python command: No symbol "vmcoreinfo_find" in current context.
|
|
|
5d360b |
|
|
|
5d360b |
Because vmcoreinfo_find() is inlined and not exported.
|
|
|
5d360b |
|
|
|
5d360b |
Use the underlying object_resolve_path_type() to get the instance instead.
