php exec gm convert problem

[eriar]

Hi all!

I have really strange problem.  I'm trying to execute this php command:

$ret1 = exec("/usr/local/bin/gm convert test.pdf test.gif", $out, $return_var);

The output is:

ret1-> string(0) "" 

out -> array(0) { }

return_var->int(1), 

and test.gif is NOT created.

 

From command line it works. ( centos 5.3, php 5.2.9, apache 2.2.3, GraphicsMagick-1.3.2 ).

This: $ret1 = exec("/usr/local/bin/gm -help", $out, $return_var); : works too, as expected.

Other commands like ls -la, whoami, etc, are working too.

 

Does anyone have a clue of how to solve this issue? Or a right question I should ask google?

 

Sorry if I'm not asking in the right place.

 

Thanks,

Eriar

A return var of 1 means execution failed. Does your server have permission to write to the directory this script is executed from?

I think it have permissions.

I tried:

$ret1 = exec("echo 123 > test.test", $out, $return_var);

And it creates test.test file.

 

Thanks for the quick answer!

It appeared to be gs problem. I installed it with yum, and everything works now. I suppose installing it from source wasn't such a good idea

Thanks!
