Experimental Physics and Industrial Control System
Hello,
I'd like to use the php epics module but I meet some difficulties.
When I am trying to launch the test_ca_get_put.php example :
<?php
#load external module
dl("php_epics.so");
#call function ca_get implemented in the php_epics.so module and display
#the result
$rt = ca_get("TEST:ai1");
echo "Channel TEST:ai1 ".$rt;
#in order to call ca_put function we want to pass a value as a parameter from
#a text field
echo "<FORM METHOD=GET ACTION=test_ca_get_put.php>\n";
echo "Channel TEST:ai2 <INPUT TYPE=TEXT NAME=CHANNEL VALUE=".$_GET["CHANNEL"].">";
echo "<INPUT TYPE=SUBMIT VALUE=Go>\n";
echo "</FORM>";
#call the function
ca_put("TEST:ai2",$_GET["CHANNEL"]);
#read and display the value
echo "Channel TEST:ai2 ".ca_get("TEST:ai2");
#Note: Channels "TEST:ai1","TEST:ai2" are running as soft channels on a PC
# on PSI network.
?>
from a web browser, I have the following display :
*"Warning*: dl(): Unable to load dynamic library
'/usr/local/lib/php/extensions/php_epics.so' - libCom.so: cannot open
shared object file: No such file or directory in
*/var/www/html/ImmsData/test_ca_get_put.php* on line *3"
*although the path to php_epics.so is correct.*
*Does anybody know what's going on ?
Thanks
Christophe
