When I try to compile Tor 85d6b41 on FreeBSD 12-CURRENT, I get this build error: ``` neel@xb3:~/code/tor/tor % make make all-am CC src/core/or/connection_edge.o src/core/or/connection_edge.c:2123:36: error: use of undeclared identifier 'O_RDWR' pf = tor_open_cloexec("/dev/pf", O_RDWR, 0); ^ src/core/or/connection_edge.c:2271:7: warning: implicit declaration of function 'ioctl' is invalid in C99 [-Wimplicit-function-declaration] if (ioctl(pf, DIOCNATLOOK, &pnl) < 0) { ^ src/core/or/connection_edge.c:2271:7: warning: this function declaration is not a prototype [-Wstrict-prototypes] src/core/or/connection_edge.c:2271:17: warning: implicit declaration of function '_IOWR' is invalid in C99 [-Wimplicit-function-declaration] if (ioctl(pf, DIOCNATLOOK, &pnl) < 0) { ^ /usr/include/net/pfvar.h:1392:21: note: expanded from macro 'DIOCNATLOOK' #define DIOCNATLOOK _IOWR('D', 23, struct pfioc_natlook) ^ src/core/or/connection_edge.c:2271:17: warning: this function declaration is not a prototype [-Wstrict-prototypes] /usr/include/net/pfvar.h:1392:21: note: expanded from macro 'DIOCNATLOOK' #define DIOCNATLOOK _IOWR('D', 23, struct pfioc_natlook) ^ src/core/or/connection_edge.c:2271:17: error: expected expression /usr/include/net/pfvar.h:1392:36: note: expanded from macro 'DIOCNATLOOK' #define DIOCNATLOOK _IOWR('D', 23, struct pfioc_natlook) ^ 4 warnings and 2 errors generated. *** Error code 1 Stop. make[1]: stopped in /usr/home/neel/code/tor/tor *** Error code 1 Stop. make: stopped in /usr/home/neel/code/tor/tor neel@xb3:~/code/tor/tor % ``` I will upload a patch for this shortly.
