I am mixing C++ with an old program written in C. Everything is wrapped with extern "C" except I have one problem, I have a struct defined in C that is extern in another module. The C++ code compiles the struct different than the C. extern "C" { typedef struct foo ... extern foo myfoo; } I am porting this app to C++, hence I need to work with C for a while until I got it all up to C++. I heven't worked with C in so long I forgot the tricks involved.

I'm not sure exactly what you're refering to. C++ should compile most C-style structure definitions just fine.

Perhaps you're trying to accomplish something like this?

#ifdef __cplusplus# define C_LINKAGE "C"#else# define C_LINKAGE#endiftypedef struct foo_t foostruct foo_t { ...};extern C_LINKAGE foo myfoo;

I think it's a problem somewhere else. It's not important right now I have alot of other stuff to deal with right now :-)

But yeah, I had C linkage, but it was mangling the structure in C++ and unsure why right now.

Thanks
