cc compiler problem

yangk — Mon, 26 Apr 2010 09:02:31 GMT

Deal All,

I have a simple c code like this:

#define _HPUX_API_LEVEL 20040821
#if !defined(__GNUC__) || (__GNUC__ < 2)
# define __attribute__(x)
#endif

#include
#include
#include
#include

int main()
{
struct utsname osname;
if(uname(&osname)<0)
{
printf("%d %s\n",errno,strerror(errno));
printf("error\n");
}
printf("%s\n",osname.release);

return 0;
}

to use the expand hostname.
But if define the following line,it will
create errors:
72 Value too large to be stored in data type
error

#if !defined(__GNUC__) || (__GNUC__ < 2)
# define __attribute__(x)
#endif

The reason is that in the /usr/include/sys/stdsyms.h there is line:

#define _HPUX_API_VERS_20040821_ATTR __attribute__((version_id("20040821")))

That may be cause the error.

So can anyone give me some help?
Thanks!

Kevin,

What OS version are you using? What C compiler version are you using?

#if !defined(__GNUC__) || (__GNUC__ < 2)
# define __attribute__(x)

You can't do this if you want to use longer hostnames.

>if define the following line, it will create errors:

Yes. It appears you already know the cause and answer, remove those bogus #if lines.
