Good day, I'm very new to ConTeXt, so maybe this is a fairly simple question. I want to use TikZ in the document. The specific part of the document is: ---- snip ---- \usemodule[tikz] \usetikzlibrary[positioning] ---- /snip ----- The problem seems to be that ConTeXt does not find the TikZ module. I use mkiv. The relevant output: ---- snip ----- % context test-document.tex mtx-context | run 1: luatex --fmt="/home/gerion/.texlive/texmf-var/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/formats/luatex/cont-en" --jobname="test-document" --lua="/home/gerion/.texlive/texmf-var/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/formats/luatex/cont-en.lui" --no-parse-first-line --c:currentrun=1 --c:fulljobname="./test-document.tex" --c:input="./test-document.tex" --c:kindofrun=1 --c:maxnofruns=9 "cont-yes.mkiv" This is LuaTeX, Version 1.0.4 (TeX Live 2017) system commands enabled. open source > 1 > 1 > /usr/share/texmf-dist/tex/context/base/mkiv/cont-yes.mkiv ConTeXt ver: 2016.05.17 19:20 MKIV current fmt: 2017.6.11 int: english/english system > 'cont-new.mkiv' loaded open source > 2 > 2 > /usr/share/texmf-dist/tex/context/base/mkiv/cont-new.mkiv close source > 2 > 2 > /usr/share/texmf-dist/tex/context/base/mkiv/cont-new.mkiv system > files > jobname 'test-document', input './test-document', result 'test-document' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > 2 > 3 > /home/gerion/sourcecode/grisu/test-document/test-document.tex colors > 'rgb' color space is supported colors > 'cmyk' color space is supported resolvers > modules > 'tikz' is not found tex error > tex error on line 6 in file /home/gerion/sourcecode/test-document/test-document.tex: !

Is this a problem of TeX Live (or the distribution packaging)? I've looked in the installed files of texlive-context and other modules are installed, even modules that require TikZ (eg. gantt). Thanks in advance, Gerion
