Try ye' olde STRINGIFY and string concatenation? Well, at least I try...
#define my_symbol my_symbol_versioned
#define STRINGIFY(a) STRINGIFY1(a)
#define STRINGIFY1(a) #a
extern void my_symbol(void);
void foo(void)
{
__asm__("call " STRINGIFY(my_symbol) "\n");
}
[bpringle@localhost bpringle]$ gcc -o x x.c
/usr/lib/crt1.o(.text+0x18): undefined reference to `main'
/tmp/ccIj9Cit.o: In function `foo':
/tmp/ccIj9Cit.o(.text+0x4): undefined reference to `my_symbol_versioned'
collect2: ld returned 1 exit status
