| Zadik | hi | 11:31.36 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 11:31.36 |
| Zadik | Hi all, i try to run ghostscript in my terminal, that part is working, when a run it in a PHP script. i get: *** Unable to open the initial device, quitting. | 11:33.09 |
| | looks like a permission issue or something | 11:33.31 |
| Robin_Watts | Zadik: no, it's down to you not specifying the device correctly. | 11:34.49 |
| | What is the exact command you are feeding to gs? | 11:34.59 |
| | Normally there will be a "-sDEVICE=something" in the command. This tells gs what sort of output to use. | 11:35.47 |
| | Like, if you want to generate full color PNGs, you'd use -sDEVICE=png16m | 11:36.05 |
| | If you call gs without specifying a command, you get the default device (which will vary according to how you built it). | 11:36.52 |
| | s/command/device/ | 11:37.01 |
| | You might get away with the default device when running from a terminal, but not from a PHP script. it all depends. | 11:37.31 |
| Zadik | i run it on a debian system, apache2: command: /usr/bin/gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=/var/www/html/pdfgen/concatzzz.pdf /var/www/html/pdfgen/test.pdf | 11:38.59 |
| Robin_Watts | Zadik: OK. We should talk about the AGPL3 then :) | 11:40.37 |
| | That sounds like you're correctly specifying the pdfwrite device, but it's refusing to open. | 11:41.32 |
| | Which may be due to a permissions problem on it not being able to open the /var/www/html/pdfgen/concatzzz.pdf file for writing. | 11:42.05 |
| | So yes, it might be a permissions problem. | 11:42.23 |
| Zadik | yes i already think about that, because it runs normale if i run it from the terminal | 11:42.39 |
| Robin_Watts | Zadik: Before we continue though, are you aware of the difference between the GPL and the AGPL ? | 11:42.43 |
| Zadik | no, i read it now | 11:42.55 |
| | but i cant see if there is a problem with that AGPL license? | 11:43.52 |
| Robin_Watts | The GPL says (basically) that if you distribute our software as part of another software package, the whole package must be GPL licensed. | 11:43.52 |
| | The AGPL says (basically) that "if you make a service available on a server, then that whole server set up counts as "distribution"." | 11:45.00 |
| Zadik | also if you use it for your own stuff? local machine? | 11:46.00 |
| Robin_Watts | No, local machine is fine. | 11:46.20 |
| | It's the moment you let other people log in to do stuff that the AGPL kicks in, AIUI. Cos that counts as 'distribution'. | 11:46.42 |
| Zadik | i know what you mean, like there are services like websites, that can do the same, but if i do that, than i understrand it. that can damage that ghostscript company | 11:48.11 |
| | but good that you say that, i have one question about that AGPL license, because it interest. like i have a invoice system, in that invoice system there are some customers. i want to merge that invoices. is that still under AGPL license? | 11:49.42 |
| | i mean with customers, to get the merged pdfs? | 11:50.11 |
| | invoices | 11:50.18 |
| | @Robin_Watts: new question if possible: that permission error, how can i locate it. is it the current directory, or does ghostscript use a other directory? | 11:53.01 |
| Robin_Watts | Zadik: I am not a lawyer. | 11:53.44 |
| | So I can't advise you on what's allowed/not allowed, other than through my own flawed understanding. | 11:54.18 |
| Zadik | okey thanks, i will research it :) | 11:54.45 |
| Robin_Watts | As to permissions, you're specifying an absolute path, not a relative one, so current directory or not is not a problem. | 11:55.08 |
| kens | pdfwrite needs to make temporary files | 11:55.30 |
| Robin_Watts | I suspect the problem is simply that the PHP script is being invoked as an unprivileged user. | 11:56.11 |
| | On ubuntu it's www-data, IIRC. | 11:56.18 |
| | so you need to make sure that any paths you use are writable from that user. | 11:56.35 |
| Zadik | i dont know where the ghostscript make the tmp folder. | 11:57.00 |
| | maybe i need to chown that | 11:57.05 |
| | is it /tmp | 11:57.14 |
| | i can try it | 11:57.18 |
| | solved :) | 12:00.26 |
| | the current directory has do www-data permission. | 12:01.19 |
| | do = no | 12:01.58 |
| | @Robin_Watts and @kens Thanks for helping me :) | 13:35.14 |
| kens | NP | 13:35.31 |
| Robin_Watts | Zadik: no worries. | 13:49.17 |
