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 Error message is rather weird on Linux: optional > using library '/home/ousia/context/tex/texmf-linux- 64/bin/lib/luametatex/zint/libzint.so' zint > unknown barcode alternative 'isbnx' zint > zint > valid barcode alternatives: zint > [...] zint > isbn zint > isbnx [...] It seems that a valid barcode alternative ends up being unknown to the library. What am I missing here? Many thanks for your help, Pablo
