Hello list, when using a 'config_site.h' with: #define PJ_CONFIG_MINIMAL_SIZE #include <pj/config_site_sample.h> ...the file pj/config_site_sample.h defines: #define PJ_IOQUEUE_MAX_HANDLES 16 This seems to be too low, because later on in line 45 of pjlib/src/pj/sock_select.c: pj_assert(sizeof(pj_fd_set_t)-sizeof(pj_sock_t) >= sizeof(fd_set)); The size of 'fd_set' is 128 at least on the Debian Linux on ARM platform I'm using (Maemo SDK with scratchbox GCC compiler). I'll leave it up to you to do the math, but the assertion will fail. Because pj_fd_set_t is an opaque buffer for fd_set, it seems reasonable to increase the value of PJ_IOQUEUE_MAX_HANDLES to 28 or even 32 should rounding off be desirable: Index: pjlib/include/pj/config_site_sample.h --- pjlib/include/pj/config_site_sample.h.orig 2008-04-07 11:19:39.000000000 +0200 +++ pjlib/include/pj/config_site_sample.h 2008-04-07 11:14:13.000000000 +0200 @@ -112,7 +112,7 @@ # define PJ_ENABLE_EXTRA_CHECK 0 # define PJ_HAS_ERROR_STRING 0 # undef PJ_IOQUEUE_MAX_HANDLES -# define PJ_IOQUEUE_MAX_HANDLES 16 +# define PJ_IOQUEUE_MAX_HANDLES 32 # define PJ_IOQUEUE_HAS_SAFE_UNREG 0 # define PJSIP_MAX_TSX_COUNT 15 # define PJSIP_MAX_DIALOG_COUNT 15 Is there a better way to report bugs than sending messages to this general purpose mailing list?
