Hello Folks,
We’ve run in to a Clang warning very similar to what was fixed in r221765, with clang reporting an unused typedef:
typedef void (*FUNCTION)(void);
void foo (FUNCTION f);
The typedef is obviously used, but get’s reported as:
$ clang --version
Debian clang version 3.6.2-+rc1-1~exp1 (tags/RELEASE_362/rc1) (based on
LLVM 3.6.2)
Target: x86_64-pc-linux-gnu
Thread model: posix
...
...
./ns3/make-event.h:605:20: error: unused typedef 'F'
[-Werror,-Wunused-local-typedef]
typedef void (*F)(U1, U2, U3, U4);
^
1 error generated.
You can browse source of this specific error instance here:
https://www.nsnam.org/docs/doxygen/make-event_8h_source.html#l00599
Can you confirm that this is a clang bug? Or our misunderstanding?
I haven’t found anything relevant on the tracker...
Thanks,
Peter
