Seb,

I've dropped the graphics list from this reply as three copies of all of 
the messages in my inbox seemed silly.

Why will static linking help you? Why only to liboctave? liboctave will 
only give you the libocatve_error_handler and 
liboctave_warning_handler.  For the Ferror function you'll also need to 
link against liboctinterp.

What about the octave_stdout [ie octave_pager_stream::stream()] . 
Doesn't it help here? As for cerr, unfortunately in error.cc the verror 
function is called with std::cerr as the output stream, so the Ferror 
function calls go straight to std::cerr. As for the 
liboctave_error_handler and liboctave_warning_handler functions defined 
in lo-error.c, these fprintf directly to stderr as well. So for the 
errors, as you say you have to capture cerr, but you'll also need to 
capture stderr for the liboctave errors and warnings...
