I was compiling a project and received an odd message that took some
digging.
e.g.
file.cpp:#:#: error: expected unqualified-id before numeric constant
# | if ( inttype == MyClass::ERROR )
^~~~~
where MyClass::ERROR is an enum.
Took some digging to find out ERROR was somewhere #define'd and the cure
was to #undef ERROR
Could never find out *where* it was defined - recursively searched all
include files of the project and /usr/include etc.
Regardless, it would have been very helpful to know in the error
messages that a #define was active or to have the ERROR replaced by the
macro substitution.
Is it possible to get any macro expansion information in error messages?
I didn't see a compiler flag for to get this information, but I might
have missed it.
If not, it would be a nice feature to have.
Cheers,
Emre.
