Call others programs in neko Web server

[Henrique Oliveira]

Hello. as I showed in the last post, I have a great interest in using neko for various tasks. Today my main job depends exclusively on some neko utilities I wrote and some members of this group have urged me to continue. I come here with another question: when trying to run a CLI command or a shell script through the Web server on neko, apparently nothing happens is the return I have is the code 127. To be precise, I am trying to convert HTML code to format PDF via 'wkhtmltopdf' utility making the call through Sys.command ()
Help.

Hello
So I found it very strange
Because I tested the same application on another machine with the same settings and software (almost a machine shadow of the other) and the second machine was fine.
I created the html (the application I'm trying to put together is a publisher of questions neko web server) and export after passing the request, he called via Sys.command the utility 'wkhtmltopdf' (which is a wonder to generate PDFs via CLI) and exported to html editing perfectly to PDF.
Well, I do not know what happens but I will investigate.
