Question

I use KnpSnappyBundle to generate PDF in my Symfony2 application. It works fine on my local wamp with the configuration :

binary:     "\"C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe\""

I trying with the application, but with a folder with wkhtmltox at the root with the configuration :

binary:     %kernel.root_dir%/../wkhtmltox/bin/wkhtmltopdf

It doesn't work. It get the following message :

The exit status code '127' says something went wrong:
stderr: "sh: wkhtmltox/bin/wkhtmltopdf: No such file or directory
"
stdout: ""
command: wkhtmltox/bin/wkhtmltopdf --lowquality

You could try to install wkhtmltopdf from https://github.com/h4cc/wkhtmltopdf-amd64

Require the package for i386 with:

composer require h4cc/wkhtmltopdf-i386 "0.12.3"

And for amd64 with:

composer require h4cc/wkhtmltopdf-amd64 "0.12.3"

The binary will then be located at:

vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386

or

vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64

For latter, services.yml will look like this:

knp_snappy:
    pdf:
        enabled:    true
        binary:     '%kernel.root_dir%/../vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'
        options:    []

    temporary_folder: '%kernel.cache_dir%/snappy'

By installing it in the vendor folder you will no more be dependent on the machine you're running your app.

I found this post via Googling, and so am posting my solution in case it helps someone.

The command being run by KNP Snappy in my case was vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386 and I got the same "no such file or directory" error from it.

I was confused, because I could see this file, and it was executable:

$ ls -al vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386 
-rwxr-xr-x 1 1000 1000 41424004 Nov  7 09:07 vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386

But when I tried to run it...

$ vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386 
-bash: vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386: No such file or directory

I was confused because it appeared that the error was that the executable didn't exist, and it clearly did exist.

In fact, the problem was that I was trying to use the 32-bit version of the executable, and my machine was 64-bit:

$uname -a
Linux mybox 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux

(see the amd64 part)

So I had to update this bit in config.yml:

knp_snappy:
    pdf:
        binary: # this was the path to the 32-bit executable; I had to update it to use the 64-bit version.
