It may be worthwhile to document an even-simpler case:

- no .d file
- no invocation of the dtrace python script
- no generated .h or .o file
- in the C file, just add:

#include <sys/sdt.h>

void main () {
/* ... */
STAP_PROBE(provider_name,probe_name);
/* ... */
}

- gcc file.c
- stap -l 'process("./a.out").mark("*")' to list
