Hi Pablo, I'm resurrecting this thread, as I've just managed to get some progress on Windows with zint in LMTX. The thing is that you need 64-bit DLL, because LuaMetaTex is built for 64-bit architecture on Windows. As it is not available, I built 64-bit zint.dll (and zlib + libpng) from the latest git sources (2.11.1.9 (dev)), renamed it to libzint.dll and placed in appropriate place, as per the instructions. But there are still some problems... here is the excerpt from the log: modules > using user prefixed file 'libs-imp-zint' modules > 'zint' is loaded open source > level 2, order 3, name 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.mkxl' resolvers > lua > loading file 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.lmt' succeeded close source > level 2, order 3, name 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.mkxl' optional > using library 'c:/Data/context/tex/texmf-win64/bin/lib/luametatex/zint/libzint.dll' zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector backend > xmp > using file 'c:/Data/context/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml' pages > flushing realpage 1, userpage 1, subpage 1 zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector I tested the library with the generated CLI tool, and I get the barcode images created. Although, png format is not working, I get file with length 0 and no error whatsoever. It could be that there is something wrong with the build, I'll try to figure out.

Dear list,

using latest LMTX and following the steps from https://wiki.contextgarden.net/Barcodes#Zint_module, I’m afraid I don’t get any barcode either in Linux or Windows.

Minimal sample:

\starttext \usemodule[zint] \barcode[alternative=isbnx, text=9783865419026, width=4cm] \stoptext [...] Are you sure that you have the latest zint? (from sourceforge) Many thanks for your reply, Hans.

I have version 2.9.2 on Linux and version 2.10 on Windows.

I’ll try to install the new version on Linux and report results here.

Many thanks for your help,

Pablo
