[PHP] Unable to execute c++ .exe file from php
I am unable to execute my c++ program from within PHP when it runs as a cgi in Apache. I am able to run: $cmd="dir c:\abc" system ($cmd, $errCode); and see the content of the directory, but I don't seem to be able to run a simple hello.exe (c++) file. $cmd = "c:\abc\hello.exe"; system ($cmd, $errCode); The errCode always comes back with 128. What does 128 mean? Here is some info on my setup. OS: Windows XP Server: Apache 2.0.43 (win32) PHP 4.2.3 I am running PHP as a CGI I am able to execute my c++ program (hello.exe) from this .php file just fine if I use the PHP cli. I appreciate any help. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Unable to execute c++ .exe file from php
I have tried escaping with backslashes and also tried forward slashes with no luck. I believe my path specification is correct because I can look at different directories. $cmd = "dir c:\abc\efg"; system ($cmd, $errCode); Correctly display the content of "efg", and the errCode is 0; I think the key to my problem is the return_var (errCode) of 128. (That is what I get in errCode when I try to execute hello.exe) Do you know where the return_var(s) for php (exec, system, ...) are defined? Is there something in php.ini that have to be set up inorder to be able to execute a file on the server? I have looked at php.net but had no luck. Thanks for your suggestions.

Re: [PHP] Unable to execute c++ .exe file from php
Very good question Mike. In my hello.cc file, I have a cout to the stdout and I open a file and write a couple of lines to it. The reason I believe it is not running is that when the .php file is running from the cli, I see my "cout" and the file (test.txt) that I open is created and my lines are written to it. When I run the same .php file from within my browser, the cout is not displayed and the file (test.txt) is not created. I am new to Windows, do you see something that I am not doing correctly? Thanks My question is how do you know it's not running? If it really is a "hello world" application, where do you want the output to go? To the browser? That's pretty involved. Try making it write to a file and see if it contains any output after execution.

RE: [PHP] Unable to execute c++ .exe file from php
When I look at the program (hello.exe) under cygwin. I see that the "x" bit is set for all. As far as I can tell anyone is permitted to execute this program. Thanks for your suggestion. --- "John W.

RE: [PHP] Unable to execute c++ .exe file from php
Thanks Ernest for your suggestion. I tried you idea with forward and backward slashes and nothing seem to change. I still see the return_var of 128. PHP is trying to tell me what the problem was, but I am unable to find what 128 means. Any idea as where the the "return_var" for the "system" and "exec" commands are defined?

Re: [PHP] Unable to execute c++ .exe file from php - Resolved
Thanks all for taking the time to help me out. I finally got the problem resolved. It appears that PHP was trying to use cygwin1.dll and could not find it. I am not sure why; I didn't think I even need cygwin to run php w/ Apache. Once I put a copy of cygwin1.dll in my system32 directory, my c++ .exe file started running. Hope this helps someone else. If someone knows why PHP needs any cygwin dlls, I would be interested in knowing the reason.
