Question

Sorry if I am wrong but I am trying to compile the libpcap for Android with NDK. Finally, I get this error:

in grammar.y we can see :

#ifndef YYBISON
int yyparse(void);

int
pcap_parse()
{
   return (yyparse());
}
#endif

=> pcap_parse is defined if YYBISON is not defined

BUT in gencode.c, we have (line 342)

lex_init(buf ? buf : "");
init_linktype(pcap_datalink(p));
(void)pcap_parse();

AND in gencode.h (line 299)

struct bpf_insn *icode_to_fcode(struct block *, int *);
int pcap_parse(void);
void lex_init(char *);
void lex_cleanup(void);

=> pcap_parse if used without any test case !!
Result is a libpcap wrong if YYBISON is defined
(undedefined function pcap_parse)

Where is my error?

Answer 1

the solution was really easy. I just do a make distclean at the sources. If it doesn’t work try to a git reset --hard and it should be fixed.

Thanks everyone
