<![CDATA[Latest posts for the topic "Aplicatia Backticks in Asterisk 1.4"]]> http://forum.modulo.ro/jforum/posts/list/1.page JForum - http://www.jforum.net Aplicatia Backticks in Asterisk 1.4
Versiunea [url=http://www.freeswitch.org/asterisk_stuff/app_backticks.c ]initiala[/url] a aplicatiei nu este compatibila cu Asterisk 1.4 astfel incat a fost necesara portarea acesteia.
[url=http://www.voip-info.org/wiki/index.php?comment_page=4&page_id=3689&comments_page=1&page=3#editcomments]Aici[/url] este o prima referinta despre aceasta portare - problema este ca sursa a fost salvata in pagina de wiki si continutul a fost compromis de formatarea interna.

Pe baza informatiilor din link-ul de mai sus am reusit sa modific versiunea initiala insa, la compilare in Asterisk 1.4.24.1 am avut erorile:
[code]
/usr/src/asterisk/asterisk-1.4.24.1/include/asterisk/lock.h:734: error: PTHREAD_MUTEX_RECURSIVE undeclared (first use in this function)
/usr/src/asterisk/asterisk-1.4.24.1/include/asterisk/lock.h:734: error: (Each undeclared identifier is reported only once
/usr/src/asterisk/asterisk-1.4.24.1/include/asterisk/lock.h:734: error: for each function it appears in.)
[/code]
Problema s-a rezolvat dupa ce am inclus si linia:
[code]
#include "asterisk.h"
[/code]
Dupa aceasta, instalarea a functionat fara probleme, cu exceptia unor mesaje de warning:
[code]
app_backticks.c:169: warning: initialization from incompatible pointer type
app_backticks.c:173: warning: no previous prototype for unload_module
app_backticks.c:183: warning: no previous prototype for load_module
app_backticks.c:193: warning: no previous prototype for description
[/code]
Pasii pentru instalarea aplicatiei sub Asterisk 1.4 sunt redati mai jos:
[code]
cd /usr/src/<asterisk_source_directory>/
cp /tmp/app_backticks.c ./apps
make
make install
[/code]
Cele 2 versiuni ale aplicatiei (pentru Asterisk 1.2 si 1.4) le puteti gasi mai jos.]]> http://forum.modulo.ro/jforum/posts/preList/78/4887.page http://forum.modulo.ro/jforum/posts/preList/78/4887.page GMT Re:Aplicatia Backticks in Asterisk 1.4 [code]
