Ah, we can easily go to the loony bin with this one. You have to start doing:
typedef struct Foo
{
Byte a;
} Foo;
#ifdef __cplusplus
class Bar
{
private:
Foo mFoo;
};
#endif
or just refactor your code and (in this case) add a ProjectTypes.h
which contains common structures and types (common

As long as you don't need to reference the C++ stuff from a .m file. But
then, should the header even be included by any .m files? Sure, there are
times when C++ and non-C++ stuff might belong together in a header, but most
of the time my C++ headers
There are some hits to using .mm rather than .m files (check the list
archives). Nothing major enough to sound any dire warnings though ;-)
And sometimes you are adding C++ to an existing Obj-C only project
(and I hate renaming every .m file to a .mm file in version control
plus the potential los
No but you include it in a Obj-C++ source file. Rename your obj-c file
with a .mm extension.

It's not the extern "C" it is just the

I do this all the time (honest). This will compile when included from
a ".m" file because _cplusplus won't be defined.
Hopefully I've got it right this time (post

That won't help if the header is using C++-only syntax like namespaces
and classes. You just can't #include that stuff from a C or Obj-C
source file.

It's in the Cocoa Dev archives (probably a subject search containing "C++").
