Hello all,
Long time user first time caller. Nice to meet you all!
I'm trying to get pjsip to work on Windows. I've compiled pjsip
into my program that I'm writing in an msys2/mingw environment
(64-bit). It compiles fine. However, when I run it in my program
I'm getting an assertion
// Line 49 of ../src/pj/sock_select.c
sizeof(pj_fd_set_t)-sizeof(pj_sock_t)>=sizeof(fd_set)
Every time I run the program.
When I do some digging people talk about increasing
PJ_IOQUEUE_MAX_HANDLES. So I did, and I put a printf in the
function before the asserts to see what the sizes are:
// My PJ_FD_ZERO variant
PJ_DEF(void) PJ_FD_ZERO(pj_fd_set_t *fdsetp)
{
printf( "PJ_IOQUEUE_MAX_HANDLES: %d, pj_fd_set_t: %I64d, pj_sock_t: %I64d, fd_set: %I64d\n", PJ_IOQUEUE_MAX_HANDLES, sizeof(pj_fd_set_t), sizeof(pj_sock_t), sizeof(fd_set) );
PJ_CHECK_STACK();
pj_assert(sizeof(pj_fd_set_t)-sizeof(pj_sock_t) >= sizeof(fd_set));
FD_ZERO(PART_FDSET(fdsetp));
PART_COUNT(fdsetp) = 0;
}
The program will output something like this:
10:27:43.477 os_core_win32.c !pjlib 2.9 for win32 initialized
10:27:43.507 sip_endpoint.c .Creating endpoint instance...
PJ_IOQUEUE_MAX_HANDLES: 16384, pj_fd_set_t: 65552, pj_sock_t: 4, fd_set: 131080
However, when I tweak PJ_IOQUEUE_MAX_HANDLES the size of
pj_fd_set_t increases as it should but! the
sizeof(fd_set) also becomes slight less than DOUBLE whatever
sizeof(pj_fd_set_t) is! The winsock guide says that I cannot set
the size of fd_set so I am very confused how the size is getting
set! I don't see anywhere in the pjsip code that this is being
set.
So adjusting PJ_IOQUEUE_MAX_HANDLES is quite the losing battle.
How can I fix this so my code will stop asserting?
The bash script that I ran to configure pjsip
