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-mingw32For 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:
checking host system type... x86_64-w64-mingw32
checking target system type... x86_64-w64-mingw32
/** Socket handle. */And thus pj_fd_set_t is smaller than fd_set *probably* because fd_set is using a bigger type for fd.
#if defined(PJ_WIN64) && PJ_WIN64!=0
typedef pj_int64_t pj_sock_t;
#else
typedef long pj_sock_t;
#endifThat'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.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:
The program will output something like this:// 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; }
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: 131080However, 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
