Subject: [PATCH 1/3] gdb: fix gnu-nat build
|
||
Content-Transfer-Encoding: 8bit
|
||
Content-Type: text/plain; charset=UTF-8
|
||
|
||
When building gnu-nat.c, we get:
|
||
|
||
CXX gnu-nat.o
|
||
gnu-nat.c: In member function 'virtual void gnu_nat_target::create_inferior(const char*, const string&, char**, int)':
|
||
gnu-nat.c:2117:13: error: 'struct inf' has no member named 'target_is_pushed'
|
||
2117 | if (!inf->target_is_pushed (this))
|
||
| ^~~~~~~~~~~~~~~~
|
||
gnu-nat.c:2118:10: error: 'struct inf' has no member named 'push_target'
|
||
2118 | inf->push_target (this);
|
||
| ^~~~~~~~~~~
|
||
|
||
This is because of a confusion between the generic `struct inferior`
|
||
variable and the gnu-nat-specific `struct inf` variable. Fix by
|
||
referring to `inferior`, not `inf`.
|
||
|
||
Adjust the comment on top of `struct inf` to clarify the purpose of that
|
||
type.
