optipng path: gifsicle path: pngout path: ALL BLANK

When I go to wp-content/ewww and run ./optipng -v, I get:

OptiPNG version 0.7.4

Using libpng version 1.4.12 and zlib version 1.2.7-optipng

This shows the newest version exists in the directory, however it still not being used by the plugin. I tried following your instruction and run “yum install glibc.i686”, however, the package was already installed.

And you don’t have the setting checked to ‘Use system paths’?

Thank you again for your reply. “Use system paths” is unchecked.

without calling my webhost support I was able to grab this info

Platform Type: Debian
MySQL Version: 5.0.91-log
Perl Version: 5.8.8
PHP Version: 5.3.13
Path to PHP: /usr/local/bin/php

also running WordPress 3.4.2.
about to upgrade to 3.5

1 suggestion the error is

optipng: MISSING?Copy binary from /hermes/bosweb25a/b209/nf.stmarytoronto/public_html/blog/wp-content/plugins/ewww-image-optimizer/ to /hermes/bosweb25a/b209/nf.stmarytoronto/public_html/blog/wp-content/ewww/

but on my webhost for security reasons obviously I can only see inside
/hermes/bosweb25a/b209/nf.stmarytoronto/, so in other words I can’t navigate from the true root

perhaps the plugin is also under the same restrictions???

serkis, 2 questions:
1. do you have command line (shell) access, so that you could browse to the wp-content/ewww/ folder and run ‘optipng -v’ ?
2. can you see if Debian is using 64-bit or 32-bit?

1.no shell access
2. Linux 2.6 Debian Lenny (v5.0) – 32 bit

serkis, that might explain why it doesn’t work then. Debian 5 is old enough that it probably has an older kernel than centos 5, and thus the bundled tools are incompatible. I wasn’t sure anyone was still using Debian 5. At any rate, I’ll see if I can setup a VM with that and re-compile the tools.

andre, I’m still working on my centos6 VM to try and replicate your issue.

That’s okay, nosilver4u! ??

You got the same issue in your VM?

not yet, just finished installing it. I’ll probably work more on it Monday.

andre,
After doing sudo yum install glibc.i686 everything works fine for me on centos6. Can you paste the output of this command:

ls -l /var/www/html/wp-content/ewww/

Hi,

ls -l /var/www/html/wp-content/ewww/ output:

total 3080
-rwxr-xr-x 1 apache apache 923929 Jan 18 15:52 gifsicle

Ok, let’s try a test…

Create a file named test.php and insert this code:

andre:

<?php
echo shell_exec('/var/www/html/wp-content/ewww/optipng -v 2>&1');
echo "<br>";
echo shell_exec('/var/www/html/wp-content/ewww/gifsicle --version 2>&1');
?>

serkis:

<?php
echo shell_exec('/hermes/bosweb25a/b209/nf.stmarytoronto/public_html/blog/wp-content/ewww/optipng -v 2>&1');
echo "<br>";
echo shell_exec('/hermes/bosweb25a/b209/nf.stmarytoronto/public_html/blog/wp-content/ewww/gifsicle --version 2>&1');
?>

If there is any output, please post the url to the test.php file so I can see it for myself.

Another possibility, add this code below the last:

<?php
echo "<br>" . shell_exec('file 2>&1');
?>
