Dear list, I am currently trying to test the lmt_axis exemple in luametafont.pdf. I am working on linux/ubuntu. The exemple leads to compilation errors below. The current version of context that I am using is from last july. I have succeeded with other examples, e.g. surfaces or lmt_text Any insight about this issue ? Many thanks.
