Hello:

I am trying to use exec() to perform a 'big' compilation via ANT but this seems to hang my IIS and also Apache Server.

Any help appreciated...

Just a guess: have you tried shell_exec() ?

http://www.php.net/shell_exec

You might need to actually exec a program that launches your compilation in the background.

Shell_exec is actually no help to you because shell_exec waits for the ENTIRE program output, so you're still blocked until compilation finishes.


Take care,

Nik
