Hi, The problem has been solved. I report it back here in case it might be helpful to others who would run into similar problems. Basically I added switch_core_init(..) and set parameters for the global variable: SWITCH_GLOBAL_dirs Below are the working codes: ====================================================================== #include <iostream> #include <switch.h> #include <QDir> int main(int argc, char** argv) { switch_core_flag_t flags = SCF_USE_SQL; bool console = true; const char *err = NULL; switch_core_set_globals(); QDir conf_dir = QDir::current(); SWITCH_GLOBAL_dirs.conf_dir = (char *) malloc(strlen(QString("%1/conf").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.conf_dir) { fprintf(stderr, "Cannot allocate memory for conf_dir."); } strcpy(SWITCH_GLOBAL_dirs.conf_dir, QString("%1/conf").arg(conf_dir.absolutePath()).toAscii().constData()); fprintf(stderr, "AAA%s\n",SWITCH_GLOBAL_dirs.conf_dir); SWITCH_GLOBAL_dirs.log_dir = (char *) malloc(strlen(QString("%1/log").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.log_dir) { fprintf(stderr,"Cannot allocate memory for log_dir."); } strcpy(SWITCH_GLOBAL_dirs.log_dir, QString("%1/log").arg(conf_dir.absolutePath()).toAscii().constData()); SWITCH_GLOBAL_dirs.run_dir = (char *) malloc(strlen(QString("%1/run").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.run_dir) { fprintf(stderr,"Cannot allocate memory for run_dir."); } strcpy(SWITCH_GLOBAL_dirs.run_dir, QString("%1/run").arg(conf_dir.absolutePath()).toAscii().constData()); SWITCH_GLOBAL_dirs.db_dir = (char *) malloc(strlen(QString("%1/db").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.db_dir) { fprintf(stderr,"Cannot allocate memory for db_dir."); } strcpy(SWITCH_GLOBAL_dirs.db_dir, QString("%1/db").arg(conf_dir.absolutePath()).toAscii().constData()); SWITCH_GLOBAL_dirs.script_dir = (char *) malloc(strlen(QString("%1/script").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.script_dir) { fprintf(stderr,"Cannot allocate memory for script_dir."); } strcpy(SWITCH_GLOBAL_dirs.script_dir, QString("%1/script").arg(conf_dir.absolutePath()).toAscii().constData()); SWITCH_GLOBAL_dirs.htdocs_dir = (char *) malloc(strlen(QString("%1/htdocs").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.htdocs_dir) { fprintf(stderr,"Cannot allocate memory for htdocs_dir."); } strcpy(SWITCH_GLOBAL_dirs.htdocs_dir, QString("%1/htdocs").arg(conf_dir.absolutePath()).toAscii().constData()); SWITCH_GLOBAL_dirs.grammar_dir = (char *) malloc(strlen(QString("%1/grammar").arg(conf_dir.absolutePath()).toAscii().constData()) + 1); if (!SWITCH_GLOBAL_dirs.grammar_dir) { fprintf(stderr,"Cannot allocate memory for grammar_dir."); } strcpy(SWITCH_GLOBAL_dirs.grammar_dir, QString("%1/grammar").arg(conf_dir.absolutePath()).toAscii().constData()); /* Initialize the core and load modules, that will startup FS completely */ //if (switch_core_init(flags, console, &err) != SWITCH_STATUS_SUCCESS) { if (switch_core_init(flags, console ? SWITCH_TRUE : SWITCH_FALSE, &err) != SWITCH_STATUS_SUCCESS) { fprintf(stderr, "Failed to initialize FreeSWITCH's core: %s\n", err); } //switch_core_init_and_modload(flags, console ? SWITCH_TRUE : SWITCH_FALSE, &err); switch_core_init_and_modload(flags, SWITCH_FALSE, &err); switch_core_runtime_loop(!console); return 0; } ==================================================================== cheers, Xing On 22/11/11 16:47, Anthony Minessale wrote:
maybe your user does not have permissions to read and write the target install dir try to chown -R to your user on all of /usr/local/freeswitch
you might want to try things the other way around and embedd your app in FS rather than embed FS in your app.

If I switch to root user I can successfully run my embedded FS app: FS_Embed. but it will fails if I run it as non-root user.
One thing I can think of to do is re-install FS as non-root. I tried but it failed to access /usr/lib/python2.7/site-packages/freeswitch.py due to the permissions.

i know you needed apr, not sure, maybe try strace or gdb

Thanks for the advice!
I tried it but still got the same error.
I added the #include <apr_general.h> and found it from /usr/local/sr/freeswitch/libs/apr/include rather than from the installed directory /usr/local/freeswitch. Hope it is the right one.
any more clues?

Hello,
Following the instructions in http://wiki.freeswitch.org/wiki/Embedding_FreeSWITCH I am trying to use Embedded FreeSwitch.
I installed FS in Fedora linux as a root user in /usr/local/freeswitch. Now as non-root user, I compiled following codes:
#include <switch.h> int main(int argc, char** argv) { switch_core_flag_t flags = SCF_USE_SQL; bool console = true; const char *err = NULL; switch_core_set_globals(); switch_core_init_and_modload(flags, console ? SWITCH_TRUE : SWITCH_FALSE, &err); switch_core_runtime_loop(!console); return 0; }
And copy the executable and conf, mod, contents of lib of the installed FS to my $MyWorkingDir.
My directory structure looks like: MyWorkingDir--bin/ (contains my executable: FS_Embed) --conf/ --mod/ --lib/ --grammars --sounds --scripts --log (I also tried to copy the contents of lib directory into MyWorkingDir)
When I run my embedded FS: ./FS_Embed, I got error
2011-11-21 18:46:26.606783 [INFO] switch_event.c:631 Activate Eventing Engine. 2011-11-21 18:46:26.617941 [DEBUG] switch_event.c:610 Create event dispatch thread 0 FS_Embed: src/switch_xml.c:2225: switch_xml_open_cfg: Assertion `MAIN_XML_ROOT != ((void *)0)' failed. Aborted (core dumped)
and occasionally on another run, I got error:
2011-11-21 16:56:51.756040 [INFO] switch_event.c:631 Activate Eventing Engine. 2011-11-21 16:56:51.767198 [DEBUG] switch_event.c:610 Create event dispatch thread 0 Segmentation fault (core dumped)
It looks like there are some things wrong with my Environment Setup for Embedded FS, but after a while of checking/trying/googling I couldn't find what's wrong.
Any advice please?
Many thanks! Xing
