    I tried it but still got the same error. <br>

    I added the #include &lt;apr_general.h&gt; and found it from

            Hello,<br>
            <br>
            Following the instructions in<br>
            <a href="http://wiki.freeswitch.org/wiki/Embedding_FreeSWITCH" target="_blank">http://wiki.freeswitch.org/wiki/Embedding_FreeSWITCH</a><br>
            I am trying to use Embedded FreeSwitch.<br>
            <br>
            I installed FS in Fedora linux as a root user in
            /usr/local/freeswitch.<br>
            Now as non-root user,<br>
            I compiled following codes:<br>
            <br>
            #include &lt;switch.h&gt;<br>
            int main(int argc, char** argv)<br>
            {<br>
                switch_core_flag_t flags = SCF_USE_SQL;<br>
                bool console = true;<br>
                const char *err = NULL;<br>
                switch_core_set_globals();<br>
                switch_core_init_and_modload(flags, console ?
            SWITCH_TRUE :<br>
            SWITCH_FALSE, &amp;err);<br>
                switch_core_runtime_loop(!console);<br>
                return 0;<br>
            }<br>
            <br>
            And copy the executable and conf, mod, contents of lib of
            the installed<br>
            FS to my $MyWorkingDir.<br>
            <br>
            My directory structure looks like:<br>
               MyWorkingDir--bin/  (contains my executable: FS_Embed)<br>
                                    --conf/<br>
                                    --mod/<br>
                                    --lib/<br>
                                    --grammars<br>
                                    --sounds<br>
                                    --scripts<br>
                                    --log<br>
            (I also tried to copy the contents of lib directory into
            MyWorkingDir)<br>
            <br>
            When I run my embedded FS: ./FS_Embed, I got error<br>
            <br>
            2011-11-21 18:46:26.606783 [INFO] switch_event.c:631

            `MAIN_XML_ROOT != ((void *)0)&#39; failed.<br>
            Aborted (core dumped)<br>
            <br>
            and occasionally on another run, I got error:<br>
            <br>

            event<br>
            dispatch thread 0<br>
            Segmentation fault (core dumped)<br>
            <br>
            It looks like there are some things wrong with my
            Environment Setup for<br>
            Embedded FS,<br>
            but after a while of checking/trying/googling I couldn&#39;t
            find what&#39;s wrong.<br>
            <br>
            Any advice please?<br>
            <br>
            Many thanks!<br>
