Sort of fixed the issue.

All,

In tracking this bug it looks like on configure the flags for PJ_WIN32 are
not being set for the build. The system isn't being detected as mingw
although it is provided in the target as seen below: x86_64-w64-mingw32

checking build system type... x86_64-w64-mingw32
checking host system type... x86_64-w64-mingw32
checking target system type... x86_64-w64-mingw32

For this reason, it seems that WIN64 is not being detected and pj_sock_t
is not being set to the proper value as shown below in
pjlib/include/pj/types.h:

/** Socket handle. */
#if defined(PJ_WIN64) && PJ_WIN64!=0
typedef pj_int64_t pj_sock_t;
#else
typedef long pj_sock_t;
#endif

And thus pj_fd_set_t is smaller than fd_set probably because fd_set is
using a bigger type for fd.

That's at least what I've come up with.

Any way to force PJ_WIN32=1 in the build instead of PJ_AUTOCONF=1 which it
is being detected?

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.csizeof(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 initialized10:27:43.507        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?
