Dear Hans, I have installed both ConTeXt LMTX and ConTeXt MKIV side by side. But I have a problem to run it. If it is OK to run a file in LMTX environment, then I got a following error when I run it in MKIV environment. “I can’t fine a file …../defFonts.tex” even though it is there. To resolve it, I run “mtxrun —generate” in MKIV. But it invoke the same type error in LMTX. Here are the command in Atom editor which I use to run it. LMTX: source /Users/graph/ConTeXtLMTX/tex/setuptex; context {filePath} MKIV: source /Users/graph/ConTeXt/tex/setuptex; context {filePath} I may avoid it by adding “mtxrun —generate” before compiling it. But it isn’t a good solution. I think that there is a better way to do this. Would you please tell me how to fix it or what is a better way? Thank you for reading.
