| tkamppeter | Hi, trying to build gpdl for my Foomatic Printer Application but have problems with building iut. | 11:50.38 |
| | Tryingh with 9.54.0 | 11:50.52 |
| artifexirc-bot | <KenSharp> And the problem is ? | 11:51.39 |
| tkamppeter | When it comes to linking I get a problem with libtiff and/or libdeflate: https://paste.ubuntu.com/p/bmT4vHxBP9/ | 11:52.16 |
| artifexirc-bot | <KenSharp> Are you using shared libraries, or the ones shipped with the GhostPDl source ? | 11:52.59 |
| | <Robin_Watts> That looks to me like you're using a system libtiff, which has been built to depend on libdeflate rather than our one which depends on libz. | 11:55.27 |
| | <KenSharp> Building from our source, no special config, on Ubuntu works correctly for me | 11:58.53 |
| tkamppeter | I have used | 12:13.21 |
| | ./configure --prefix=/usr --without-x --disable-gtk --enable-freetype --without-tesseract | 12:13.24 |
| | Should this not use the internal libtiff? | 12:13.39 |
| artifexirc-bot | <KenSharp> Beyond my noobn level of expertise..... | 12:13.59 |
| | <KenSharp> I suspect you may need Chris, I think he's at lunc at the moment. | 12:14.17 |
| | <KenSharp> I can try that config locally though | 12:14.28 |
| | <KenSharp> But that may not tell me anything, I'm not sure what the system libtiff on this setup is | 12:14.52 |
| | <KenSharp> When you run ./configure, does it run the libtiff configure script ? | 12:17.04 |
| | <KenSharp> It certainly appears to be using the llibtiff from the Ghostscript source tree for me | 12:18.16 |
| | <KenSharp> Ah, and again, when running configure, what is the value of SHARE_LIBTIFF ? | 12:18.51 |
| | <KenSharp> For me its 0 | 12:18.54 |
| tkamppeter | It runs ./configure of libtiff: https://paste.ubuntu.com/p/ZQxNBzXfC6/ | 12:23.00 |
| | And in config.log (of ghostpdl, main dir) SHARE_LIBTIFF is 0. | 12:23.55 |
| artifexirc-bot | <KenSharp> Then its beyond me, I am not an expert in build systems on Linux | 12:24.15 |
| chrisl | It's finding both libz and libdeflate - I don't what it does when it finds both | 12:24.24 |
| artifexirc-bot | <KenSharp> It works for me as expected | 12:24.28 |
| tkamppeter | chrisl, I cannot simply uninstall libdeflate-dev, as libtiff-dev needs it. | 12:25.11 |
| | chrisl, can I inject command line options to the .configure of the built-in libtiff? | 12:25.46 |
| chrisl | It means changing the invocation of the libtiff configure when it's called from ours.... let me do a quick experiment | 12:27.09 |
| | Well, that doesn't appear to be the problem, since it works just fine for me :-( | 12:29.58 |
| tkamppeter | chrisl, I am on Ubuntu 21.04 (Hirsute). | 12:30.26 |
| chrisl | I'll have to setup a VM, then | 12:33.17 |
| tkamppeter | chrisl, could you do so? Great. | 12:36.35 |
| chrisl | tkamppeter: While that's happening, I should point out that gpdl includes GhostPCL, and that requires (and includes) fonts that are not GPL licensed | 12:42.06 |
| tkamppeter | chrisl, I will not need the PCL input part for my use case. So I would not build that part of GhostPDL, I only need the CUPS/PWG/Apple Raster input part. By the way, which ./configure options suppress the build for the unneeded input formats (I also would not need TIFF as input format)? | 12:44.41 |
| chrisl | There isn't one(s) | 12:48.04 |
| tkamppeter | chrisl, so my use-case of raster-only->GS graphics engine is not (yet) covered? So ghostpdl only builds with a proprietary software blob (which I actually do not need)? | 12:49.55 |
| chrisl | GhostPDL builds with all the PDLs we support which includes PCL5, which requires fonts that are not available under the (A)GPL | 12:51.11 |
| tkamppeter | chrisl but can I build it without these fonts and then simply only use it with CUPS/PWG Raster as input? I will only put it in Snaps where users do not call it directly, so no one sees that with PCL input it does not work. | 12:52.51 |
| chrisl | tkamppeter: Possibly. Frankly we can solve the problem in a few ways, I was wanted to let you know that *right now* the license would be a problem for you | 12:54.30 |
| tkamppeter | chrisl, in general it would be a great feature for GhostPDL to allow the user to select by ./configure options which input formats he actually wants, especially as we do not only use the classic Debian and RPM packaging where we want to activate as much functionality in the package as we can but we also have the sandboxed/Snap packaging, where each Snap has its dependencies built-in and so we build these dependencies | 12:59.32 |
| | individually for the Snap only activating what the Snap actually needs. For example in the PostScript Printer Application Snap I build Ghostscript with only the ps2write device as there Ghostscript only serves for turning PDF into PostScript. | 12:59.32 |
| | For a Printer Application retro-fitting built-in drivers of Ghostscript it makes sense to build a Ghostscript/GhostPDL which takes only PDF and PWG/CUPS/Apple Raster as input. | 13:01.25 |
| chrisl | For a real printer, it generally means a customized makefile, anyway | 13:03.08 |
| tkamppeter | Therefore my feature request is to allow selection of supported input formats via ./configure options, for easy creation of sandboxed packages. | 13:03.11 |
| chrisl | I don't have a problem the idea, I just don't know, off the top of my head, how much work is involved. I'm willing to look at it, when I have the time | 13:07.08 |
| tkamppeter | chrisl, OK | 13:07.28 |
| | chrisl, KenSharp, I think for the Foomatic retro-fit I will go with the encapsulation of the Raster input in PostScript, as this would allow for keeping the foomatic-rip filter unchanged and so lowers the risk of something to break which I cannot test. | 13:09.16 |
| chrisl | tkamppeter: Personally, I think that is probably for the best. I feel it will give you the most flexibility | 13:15.45 |
| | tkamppeter: I do indeed see the build gpdl problem with Ubuntu 21.04 - I'll look into that | 14:13.16 |
| | s/build gpdl problem/gpdl build problem | 14:15.21 |
| | I do wonder why it doesn't happen on 20.10... but never mind. | 14:22.32 |
| Antonio81 | Hello everyone | 17:25.24 |
| | how are you? | 17:25.27 |
| ghostbot | mas o menos, Antonio81 | 17:25.27 |
| artifexirc-bot | <KenSharp> had no idea ghostbot spoke other languages | 17:25.52 |
| Antonio81 | I am getting unrecoverable error exit code 1 | 17:26.05 |
| | but just that, no more info | 17:26.14 |
| | is there any log ghostscript writes? | 17:26.21 |
| artifexirc-bot | <KenSharp> No | 17:26.27 |
| | <KenSharp> Everything is sent ro stdout or stderr | 17:26.40 |
| | <KenSharp> Everything is sent to stdout or stderr | 17:26.59 |
| Antonio81 | and if I use gswin64.exe, does it help? | 17:27.13 |
| artifexirc-bot | <KenSharp> Of course, you haven't quoted the entire back channel, given us a command line, and you may have set things like -dQUIET which would suppress output | 17:27.31 |
| Antonio81 | im using gswin64c.exe and gs is not printing erros to dos | 17:27.33 |
| | huum | 17:27.45 |
| artifexirc-bot | <KenSharp> I doubt you are using DOS 🙂 | 17:27.46 |
| | <KenSharp> Possibly you mean the command shell | 17:27.52 |
| Antonio81 | cmd | 17:27.54 |
| | yup | 17:27.55 |
| | -sDEVICE=pdfwrite -sDEFAULTPAPERSIZE=a4 -dCompatibilityLevel=1.4 -dBATCH -dNOPAUSE -o %%f.tmmp -f %%f | 17:28.26 |
| artifexirc-bot | <KenSharp> There is little difference between gswin64c and gswin64. Its just that you can drag-and-drop to the window, and it captures stodut and stderr and writes the output to the window | 17:28.29 |
| Antonio81 | -q -o %%f.PCL -sDEVICE=ljet4 -dBATCH -dNOPAUSE -f %%f | 17:28.36 |
| artifexirc-bot | <KenSharp> You appear to have two DEVICE switches | 17:29.00 |
| | <KenSharp> You can't do that. | 17:29.04 |
| Antonio81 | i can | 17:29.08 |
| | its working well | 17:29.10 |
| | its not the same command | 17:29.14 |
| artifexirc-bot | <KenSharp> Well if its two different commands and not a follow on you do really need to make that clear | 17:29.39 |
| Antonio81 | sorry, you are right | 17:29.50 |
| | gswin64c.exe -sDEVICE=pdfwrite -sDEFAULTPAPERSIZE=a4 -dCompatibilityLevel=1.4 -dBATCH -dNOPAUSE -o %%f.tmmp -f %%f | 17:29.57 |
| artifexirc-bot | <KenSharp> And -q is 'queit' so you don't want to do that if you are having a problem | 17:30.00 |
| Antonio81 | ah f... | 17:30.17 |
| artifexirc-bot | <KenSharp> Not saying it will help, but its possibly more information | 17:30.46 |
| tkamppeter | Is there a PostScript command which makes Ghostscript exiting with error code 1 (or any given error code)? I know that one can end Ghostscript with "quit" but this gives exit code 0. | 19:53.36 |
| artifexirc-bot | <RayJohnston> tkamppeter: Ghostscript exits with 1 after an error, so anything that causes an error will do it. Try: bin/gs -c clear pop ; echo $? | 21:07.49 |
| | <RayJohnston> Of course, this will do the message/error_handler for 'stackunderflow", but the exit code is 1 | 21:07.49 |
| | <RayJohnston> If you don't want the message, you could redefine the error handler before doing that, and it will still exit | 21:08.41 |
| | <RayJohnston> or you can do: bin/gs -q -dBATCH -sDEVICE=bbox -c 1 1 .quit ; echo $? | 21:15.25 |
| | <RayJohnston> that just prints: GPL Ghostscript GIT PRERELEASE 9.55.0: Unrecoverable error, exit code 1 | 21:15.51 |
| | <RayJohnston> (you may not need the -sDEVICE=bbox (my system couldn't open the x11 device, so it gave a different error message) | 21:16.44 |
| | <RayJohnston> note that "0 10 quit" will print: GPL Ghostscript GIT PRERELEASE 9.55.0: Unrecoverable error, exit code 10 but still exit with the system exit value of 1 | 21:18.54 |
| | <RayJohnston> note that "0 10 .quit" will print: GPL Ghostscript GIT PRERELEASE 9.55.0: Unrecoverable error, exit code 10 but still exit with the system exit value of 1 | 22:31.37 |
