how to debug c++ code called from php using exec() -

-

I am calling some C ++ code in my php app using "exec" as I have explained that I Once I execute it, I debug C ++ code. The C + + app starts and ends with a faster way for example with Eclipse attached to the process. Any idea how to debug C ++ code is called php with AP (exec)? I'm on Linux using Eclipse and GDB.

The php ap workflow is: get value from HTML form, these values ​​are called exec () with C ++ code, get output from C, then using php on cHTML it Display it is a PHP controller and the C ++ model. In fact it depends on how you are using PHP code in the first place if you have a Using PHP to create web pages, where you do some C ++ code between the HTML (or whatever) generation, it is a bit difficult. If you are using the command line to run PHP, you can just type $ command to "myprog arg1 arg2 in " gdb --args myprog arg1 arg2

If you can not debug the actual application (because "MyProgram" output is part of your web page Is, for example), so I just run $ gdb --args myprog arg1 arg2 on the command line on the machine, and debug the code standalone Or, if you have to debug it as part of the web-app, you might add sleep (10); at the beginning of "myprog" , And gdb attach X where X is the process ID (from top or ps aux | grep myprog , for example) - sleep (10); line, and gdb command continue .
