comprehending the build message

[Sudeepam Pandey]

All,

    I was following the HACKING.md file to build octave dev. The *make -j2* command exits with the following message...

  MAKEINFO ../doc/interpreter/octave.info
  TEXI2DVI doc/interpreter/octave.dvi
/usr/bin/texi2dvi: etex exited with bad status, quitting.
Makefile:27883: recipe for target 'doc/interpreter/octave.dvi' failed
make[2]: *** [doc/interpreter/octave.dvi] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory '/home/sudeepam/SUDEEPAM/octave/.build'
Makefile:26444: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/sudeepam/SUDEEPAM/octave/.build'
Makefile:10182: recipe for target 'all' failed
make: *** [all] Error 2

Can anyone explain what this means?

What confuses me more is that, these 'errors' are there after the make -j2 command but I can run octave from the run-octave file inside the .build folder (basic operations like 5+5, 8*8 etc are all working).

I am confused whether Octave was build correctly or not. Can anyone help please?
