Hello
I haw an appl, which do a error:
/lib/libc.so.6: version `GLIBC_2.7' not found
But the only symbol it needs from glibc 2.7 is
__isoc99_sscanf@@GLIBC_2.7
I want to write a small 1 function "library" with this symbol as alias to __sscanf()
How can I do this with gcc/ld?
My variant is not accepted because "@@" symbols
int __isoc99_sscanf@@GLIBC_2.7(const char *, const char *, ...) __attribute__((alias("__sscanf")));
second my variant is
#include <stdarg.h>
int __isoc99_sscanf1(const char *a, const char *b, va_list args)
{
int i;
va_list ap;
va_copy(ap,args);
i=sscanf(a,b,ap);
va_end(ap);
return i;
}
// __asm__(".symver __isoc99_sscanf,__isoc99_sscanf@@GLIBC_2.7");
__asm__(".symver __isoc99_sscanf1,__isoc99_sscanf@@GLIBC_2.7");
but it ends with "version node not found for symbol __isoc99_sscanf@@GLIBC_2.7"
