expected constructor, destructor, or type conversion before â;â token

Hi All,

I am facing an error "expected constructor, destructor, or type conversion before â;â token"in the below code:

#ifdef SUN
extern "C" gethostname(char*, int);
#endif

Any help will be appreciated

Just to mention that this error came in g++ in Linux

Code:

#ifdef SUN
extern "C" {
    int gethostname(char *, size_t);
}
#endif

Hi Nominal,

Thanks a lot, it worked but here my question is how it perfectly compiled in solaris using CC Compiler that too without using curly braces

The braces were not the issue, although I do recommend always using them, it makes it easier for humans to read.

Code:

#ifdef SUN
extern "C" int gethostname(char *, size_t);
#endif

The reason it worked in Solaris is because there the compiler was so old it still treated a C function prototype without explicit return type as returning int. (I think. I didn't actually check.)

Just because it worked in Solaris does not mean it should work in general. We have standards for that, and Solaris is not exactly known for following standards.
