[mkeeter]

If you revert back one commit (to 8b805c6), does it work?

It seems like the failing step is

/usr/local/bin/lemon -q -c -s /home/alex/soft/cad/antimony/lib/fab/src/tree/v2syntax.y

Can you try running that on its own, possibly using ptrace to figure out where it's trying to find lempar.c? It appears that lempar.c is a part of lemon, but dunno where Ubuntu normally puts it.

It now fails in a different place:

I'll see about ptracing that command.

[prokoudine]

locate tells me this:

/usr/local/share/lemon/lempar.c
/usr/share/lemon/lempar.c

The former one was installed along with brl-cad. The latter one was installed as part of the lemon package on Ubuntu.

[mkeeter]

Okay, this appears to be a disagreement between the lemon executable and the Ubuntu package.

lemon looks for lempar.c in the same directory as the binary (see pathsearch here), i.e. /usr/local/bin/lempar.c, but Ubuntu has put it in /usr/share/lemon/lempar.c.

Homebrew patches this here; perhaps Ubuntu should be doing something similar?

(I also can't explain why this worked in the past!)
