| | <<<Back 1 day (to 2016/09/29) | 20160930 |
| ago | good morning | 10:02.07 |
| | Robin_Watts: I noticed that mupdf is broken with the latest openjpeg. Are you aware? is there a fix? | 10:02.37 |
| | https://bpaste.net/show/2fb6ad81f500 | 10:03.16 |
| jogux | ago: Robin's in the US at the moment, he may not be online for at least a few hours (or possibly not till next week). | 10:10.19 |
| | ago: I'm not a mupdf developer, and I've not been following as to your project, but generally if you want to guarantee compatibility it's best to use the version of openjpeg that is in the submodule under the mupdf repo. | 10:11.20 |
| ago | jogux: in gentoo we are not using bundled library | 10:26.03 |
| jogux | I thought that might be the case :-) I don't know what the outcome will be then. From your log it sounds like there's been a major API rework if functions like opj_create_decompress are no longer there. | 10:27.54 |
| | although opj_create_decompress still seems to be there in the latest openjpeg git. which version are you referring to when you say 'latest'? | 10:29.32 |
| ago | jogux: 2.1.1 and 2.1.2 | 10:45.43 |
| | jogux: for reference: http://bugs.ghostscript.com/show_bug.cgi?id=697175 | 10:46.25 |
| jogux | cool, I'll leave it to Robin to comment. I'm confused currrently :) | 10:48.34 |
| ago | jogux: are you able to build with the latest openjpeg? | 10:52.57 |
| jogux | I haven't tried. My main confusion arises because the symbols your linker says are missing appear to be present in the latest openjpeg git. | 10:53.50 |
| | Robin update openjpeg on master just two days ago, I don't know if that is relevant. | 10:54.32 |
| jogux | has my head deep in something else at the moment :) | 10:54.53 |
| ago | jogux: this may probably come from downstream changes, since we need to touch the makefile.... | 10:57.44 |
| | I guess would be great have at least a configure | 10:58.24 |
| jogux | One answer you may well get is: don't do that ;-) (ie. use the embedded openjpeg. but I don't want to pre-guess, particularly as I've not followed the earlier discussions.) | 11:00.59 |
| | I'm probably not really help tbh so I should shutup :) | 11:01.48 |
| raj_ | i need your help | 13:14.55 |
| | here any one knows how to create libfontconfig.a file for ios | 13:15.28 |
| | ? | 13:15.32 |
| | i am very new for ios could you please help me | 13:15.55 |
| jogux | raj_: I think you may be in the wrong place. This channel is for ghostscript or mupdf issues, and I don't believe either of those have a libfontconfig | 13:25.15 |
| deekej | hello guys, question: | 14:55.58 |
| | does the new ghostscript-9.20 also included the changes to Openjpeg2? | 14:56.20 |
| | *include | 14:56.36 |
| | I see you made some changes in the git to update to latest openjpeg2, it was 3 days ago | 14:57.16 |
| | and 3 days ago the 9.20 was released | 14:57.28 |
| | and on github it says that openjpeg2.1.2 was released 2 days ago | 14:57.56 |
| | I can't get a head or tail from this timeline | 14:58.10 |
| jogux | deekej: I suspect anyone that knows the answer to that question is offline today due to a staff meeting | 14:59.57 |
| | deekej: but here's the release branch: http://git.ghostscript.com/?p=ghostpdl.git;a=shortlog;h=refs/heads/gs920 | 15:00.04 |
| | I'm going to say that's not got anything from 2 days ago in it. | 15:00.14 |
| deekej | okay, thanks :) | 15:06.22 |
| Stealth | hey there, anyone from mupdf dev team? | 15:06.23 |
| jogux | Stealth: there likely won't be anyone till Monday. | 15:10.39 |
| Stealth | oh well | 15:10.58 |
| | sounds like I've found DoS issue | 15:11.26 |
| jogux | Stealth: if you want to make a private bugzilla entry I can help with that. | 15:13.43 |
| Stealth | yes please, but I think I need to create an account there first. | 15:14.29 |
| jogux | you will. :) | 15:17.13 |
| Stealth | let me do that then | 15:18.39 |
| sebras | ago: Robin: it seems like openjpeg removed a few deprecated interfaces in openjpeg 2.1.0 as outlined here https://github.com/uclouvain/openjpeg/blob/master/NEWS.md | 15:24.39 |
| | one of them is indeed opj_stream_destroy() | 15:24.58 |
| | is that the reason that the library is rejected and that all symbols are listed as undefined in ago's log in 697175. | 15:25.37 |
| jogux | sebras: This still confuses me. http://www.openjpeg.org/abi-check/timeline/openjpeg/ says nothing has been removed in the last 2 years. (and it appears to be up to date) | 15:27.52 |
| | ah, good, Robin is confused too | 15:31.50 |
| sebras | jogux: let me check the code, maybe the openjpeg guys are deliberatly trying to confuse us all. :) | 15:32.08 |
| jogux | I am tempted to suspect ago's problem is some kind of configuration issue. | 15:32.40 |
| | (like it's not actually pulling in openjpeg at all) | 15:34.12 |
| ago | sebras: I admit that the Makefile is not fantastic...so we need to to a massive edit to force it to respect variables....and there is also a patch from debian on openjpeg O_o | 15:45.51 |
| inkbottle | Some pdf (eg: http://www.cis.upenn.edu/~jean/geomcs-v2.pdf), have weird font vertical metrics for some fonts (eg minus sign p95), making highlighting annotations ugly. Would it be possible to amend the metrics of that font? | 15:46.37 |
| ago | sebras: not hard to understand: https://gitweb.gentoo.org/repo/gentoo.git/tree/app-text/mupdf/mupdf-1.9a.ebuild | 15:47.03 |
| | sebras: and here you can see that something is suitable to go into upstream master: https://gitweb.gentoo.org/repo/gentoo.git/tree/app-text/mupdf/files | 15:47.17 |
| | sebras: anyway have at least a configure would be great..... | 15:47.28 |
| | sebras: err, is not from debian....is here for any reason I don't know.. | 15:49.52 |
| jogux | ago: I don't understand ebuild at all. It really looks to me like the issue is caused by the changes you make to use a system openjpeg, I don't think those changes are working right. | 15:53.26 |
| ago | jogux: if 1.9a works with openjpeg-2.1.2 on your side, maybe is a downstream fault... | 15:54.43 |
| | but we always used external library | 15:54.57 |
| jogux | I'm not guaranteeing that, but 1.9a definitely doesn't break like /that/ with openjpeg-2.1.2. | 15:55.42 |
| | ago: I think you need to print out the linker command, check that openjpeg is being linked in, and if it is, check the openjpeg library containis those symbols. | 15:56.43 |
| | the most obvious explanation to me just know would be that openjpeg isn't even been linked in | 15:57.04 |
| | s/know/now/ | 15:57.10 |
| sebras | ago: it seems to me that the patch for openjpeg you apply: http://goo.gl/H7Pnsv is already applied in mupdf: http://goo.gl/bfCa7M | 15:57.31 |
| ago | sebras: ok, I got another error without the patch... | 15:59.50 |
| | :/ | 15:59.52 |
| | sebras: https://bpaste.net/show/5babf5ccddd6 | 16:01.48 |
| jogux | sebras: that change isn't there in 1.9 though, http://git.ghostscript.com/?p=mupdf.git;a=blob;f=source/fitz/load-jpx.c;h=6b92e5c8c507336e0cdc4db7c7dea3ab855bf5ed;hb=027860688eafc89ca3d57937a77a43a9bb96f590#l120 | 16:02.28 |
| sebras | ago: wait a minute... are you trying to build the very latest mupdf or 1.9a? | 16:03.01 |
| ago | sebras: 1.9a | 16:03.08 |
| sebras | ago: oh, I though you were trying to build the latest git HEAD. | 16:03.27 |
| | ago: so my link was to latest git HEAD. | 16:03.42 |
| jogux | aiui ago is trying to package mupdf 1.9 for gentoo | 16:03.55 |
| | 1.9a, sorry | 16:04.01 |
| sebras | ago: so basically you are building mupdf 1.9a with the very latest openjpeg? | 16:04.08 |
| ago | sebras: 2.1.2 | 16:04.16 |
| sebras | ago: right. | 16:04.21 |
| ago | sebras: does it work for you? | 16:04.33 |
| sebras | ago: I haven't tested because I use the bundled openjpeg normally. | 16:07.20 |
| | ago: as I remember it openjpeg 1.5 used the interface opj_stream_set_user_data(opj_stream_t *, void *) while openjpeg 2.1 introduced opj_stream_set_user_data(opj_stream_t *, void *, opj_stream_free_user_data_fn) | 16:08.49 |
| | ago: I haven't checked yet, but I believe that maybe mupdf 1.9a used an older version of openjpeg with the older interface. | 16:09.20 |
| | ago: if I'm correct then this is the reason that you are failing to use a newer version of openjpeg with 1.9a of mupdf. | 16:09.53 |
| ago | sebras: do you know when 2.0 will be released? I guess the latest git head should work with the latest openjpeg.. | 16:10.00 |
| officergris | ago: I have mine working with openjpeg 2.1.0. do you know if there's a major difference with that version? | 16:10.28 |
| ago | sebras: is there a particular reason because mupdf uses bundle software instead of system libs? | 16:10.41 |
| | officergris: with 2.1.0 worked also for me, the problem is 2.1.2 and perhaps 2.1.1 | 16:11.01 |
| sebras | ago: yes, I see that the version of openjpeg we bundled with 1.9a wasn't 1.5 as I assumed but something upstream labelled 2.0.0 | 16:13.22 |
| | ago: I think the main reason is that openjpeg changed their interface and mupdf hasn't changed accordingly in 1.9a (but this is the corrected in the upcoming 1.10 version) | 16:14.09 |
| | ago: normally the main reason projects keep bundled libraries is that they want known/stable versions of used libraries. | 16:15.58 |
| officergris | ago: just upgraded to openjpeg-2.1.2 and I am getting a similar problem | 16:16.06 |
| ago | officergris: yeah.. | 16:16.17 |
| | sebras: is there a chance to have a configure to manage better the variables on our side? | 16:16.43 |
| sebras | ago: I'm not the one to make that decision, but mupdf has not had any autotools-based scripts for a long time so I'd not expect that to change any time soon. | 16:17.39 |
| ago | sebras: just as personal suggestion since in gentoo I see every day similar problems...autotools-based is better and where possibile avoid to bundle, unless you have a --with-system-lib :) | 16:21.22 |
| | works end....se you. | 16:21.34 |
| sebras | ago: I think the reason for you problems is that 1.9a was using a version of openjpeg with the old interface where opj_stream_set_user_data() took two arguments and that worked fine until you upgrade to a newer version of openjpeg where they have changed the interface to take three arguments and then you get a compilation error. | 16:22.51 |
| | ago: we adapt to the new interface in the upcoming 1.10 because we upgrade to a later version of openjpeg. | 16:23.13 |
| | ago: note that all distributions (each having stable and development versions) may have different versions of system libraries. which ones should we test with? all distributions for all versions? that's a lot. :) | 16:24.34 |
| | officergris: I have no idea what the differences are between openjpeg 2.1.0 and 2.1.1 and 2.1.2. | 16:28.31 |
| LordNed|Work | Hi all. I can't seem to find the documentation on mupdf's "fz_open_document_with_stream" - not entirely sure what it's expecting for magic or how to make an fz_stream | 20:36.31 |
| | (We're writing a managed C# rapper around mupdf and want to open the file via C# and convert it to a byte array before going to unmanaged c) | 20:37.33 |
