Issue running unoconv from php script with shell_exec

Question

I am unable to use unoconv to convert a .doc to PDF from php using exec. Here is what I am trying:

$output = exec("unoconv /opt/bitnami/apache2/htdocs/=".$fileData['name']);
error_log(print_r($output, TRUE));

This command, when run in the console works perfectly, but when run through php, it gives the following in the error logs:

python: /opt/bitnami/common/lib/libcrypto.so.1.0.0: no version information available (required by python)
python: /opt/bitnami/common/lib/libssl.so.1.0.0: no version information available (required by python)
Aborted
[Thu Mar 28 20:13:58.312843 2013] [:error] [pid 1481] [client ***]

I don't think the first two lines are relevant, and I'm not sure how to get more information on why it aborted. I also have tried running it using this wrapper stored in /usr/local/bin/unoconv.sh

#!/bin/bash

if [ -z "$1" ]; then
    echo "Must pass file";
    exit 10;
fi

/usr/bin/unoconv -f pdf $1.rtf

But that gives the error

python: /opt/bitnami/common/lib/libcrypto.so.1.0.0: no version information available (required by python)
python: /opt/bitnami/common/lib/libssl.so.1.0.0: no version information available (required by python)
/usr/local/bin/unoconv.sh: line 8:  2886 Aborted                 /usr/bin/unoconv $1
[Thu Mar 28 20:17:05.331830 2013] [:error] [pid 1188] [client ***]

Any ideas on what else to try? Thanks for your help

run: `apt-get install openssl` and than: `pkg-config --libs openssl`, and check your script. — mkjasinski, Mar 28 '13 at 20:42
If I remember correctly you don't have an environment when you do shell_exec or similar. That means that all your paths and other settings are not available. Also consider that you do the shell exec as the webserver's user so it may be that this user cannot access certain components in the system. — herrjeh42, Mar 28 '13 at 20:44
Running `apt-get install openssl` overwrote the existing package, but it still says no package 'openssl' found. — davis, Mar 28 '13 at 20:47
@jamie0726 Is there anyway around this? It seems like using the wrapper would work. — davis, Mar 28 '13 at 20:48
@DavisG. check out this post how to set env variables in combination with shell_exec http://stackoverflow.com/questions/3571582/how-to-set-command-line-enviroment-variable-in-php-shell-exec — herrjeh42, Mar 28 '13 at 20:55
It is 1.0.1 and it is found in the directory /opt/bitnami/common/lib/pkgconfig — davis, Mar 28 '13 at 20:55
@jamie0726 Sorry, I'm not sure how I would use this as a solution — davis, Mar 28 '13 at 20:59
you have to find out what env variables unoconv is missing (I never used it, so I can't help you on this). But here's a posting which looks interesting how to continue debugging: http://askubuntu.com/questions/96512/php-shell-exec-in-ubuntu — herrjeh42, Mar 28 '13 at 21:06

I've done it with exec();

$path_exe = "\"C:\Program Files (x86)\LibreOffice 4\program\python.exe\" c:\unoconv\unoconv -f png ";
exec('"C:\Program Files (x86)\LibreOffice 4\program\python.exe" c:\unoconv\unoconv -f pdf 'c:\'.$filename, $array_buffer, $code_error);

You should specify the path to the python.exe, and the path to unoconv
