Call C++ lambda functions from gdb
Project description
gdb-call-lambda
Call C++ lambda functions from gdb.
Install
- Install the Python package in somewhere Python can see.
- In .gdbinit add:
python import gdb_call_lambda
Usage
Call a lambda like printl f(x)
, where the f
is the lambda.
I.e., call as usual, just replace print
with printl
.
The lambda expression (f
in this case) must not have any (
characters.
Alternatively, use the convenience function: print $calll(f, x)
How it works internally/what to do if it doesn't work
See post https://stackoverflow.com/a/70254108/5267751.
There's a known bug where gdb/tools can't demangle a symbol that gcc generates, see B
in test.
