Therion expects to find a *bbox file for each scrap containing labels. It is generated by metapost when the labels are processed. In your case, you instructed metapost to skip all the labels in a scrap (so no *bbox file was produced), but therion knows there were some labels defined for that scrap (if you displayed at least one label in the scrap, the *bbox file would be generated). The easiest solution is to create an empty *bbox file if there is none by writing an empty string to it. Here is a modified Marco's macro: vardef p_label@#(expr txt,pos,rot,mode) = if known ATTR_visibility: if ATTR_visibility="on": % ADDED CONDITIONS if (mode=1) or (mode=7): interim labeloffset:=(u/8). fi; lab:=thelabel@#(txt, pos); if mode>1: pickup PenD fi; if mode=1: % altitude pickup pencircle scaled (u/6); drawdot(pos); process_label(pos,0); elseif mode=2: process_uplabel; % passage height positive elseif mode=3: process_downlabel; % passage height negative elseif mode=4: process_updownlabel; % passage height both elseif mode=5: process_circledlabel; % passage height unsigned. elseif mode=6: process_boxedlabel; elseif mode=7: process_label(pos,rot); % station name elseif mode=8: process_filledlabel(pos, rot); else: % mode=0 date process_label(pos,rot); fi; else: write "" to jobname & "." & decimal(charcode) & "bbox"; fi; else: write "" to jobname & "." & decimal(charcode) & "bbox"; fi; % END OF CONDITIONS enddef; > However, if I put in the –d command it compiles and produces the warning: > warning -- cavern exit code – 1 > But it creates a nice map showing the labels I want. There was surely some old data.8bbox file in the thTMPDIR, as therion doesn't clean this directory between runs in the debug mode. Check the timestamps of the files.
