Yesterday I spent what little time I had to mend the FLTK and graphing code so it worked. Today after an update I find that it is broken again. Please can whoever fiddled with this yesterday please either restore or fix the code?

I had a browse through the sourceforge CVS html browser and it says there that neither widgets.cpp nor FL_graph.cpp have been changed for the last 2 weeks. Yesterday I updated SConstruct to do with Tclcsound building on linux, but never touched anything else. What was supposed to have been changed?

If I knew what had changed I could (probably) fix it. What I do know
is that following the search for why there were no graphs I fixed it,
and on Monday 14:15 lecture I used Csound5 in my class, and in
particular showed them a graph. This morning I did a cvs update (as I
do most mornings before breakfast) and rebuilt. Now there are no
graphs, so something changed to cause them to break.
I did restore the error messages in csmodule.c so I now know that the
problem is related to the undefined symbol _ZN9Fl_Widget5labelEPKc
which is referenced in libwidgets.so but does not get resolved. C++
name mangling I suspect (one of the reasons I dislike C++) would
suggest that this is a method on FL_Widget but which one and where I
am unable to determine. (no I did not update FLTK -- unchanged since
August). I suspect a change in SConstruct but am very unsure as to
where. Could
widgetsEnvironment.ParseConfig('fltk-config --ldflags')
not do what I expect? This area does not look like it is not exactly
what I wrote but I cannot find out what differs.

I have just updated and rebuilt. FLTK widgets work on Linux as
before, as well as the graphs. The only thing I noticed, but
that's how it was yesterday, is that on ctrl-c I get
"csound tidy up: segmentation fault", which is a little nasty
and wasn't there before. Perhaps Istvan (if he's still here) might
have a clue why (it doesn't happen on OSX).

It seems as the problem I was having was that we now require FLTK 1.1.6 but I only had 1.1.4 installed on that machine. Some change triggered a rebuild of libwidget.so and hence the problems. Still very confused as to exactly how/why. ==John ffitch ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ Csound-devel mailing list Csound-devel@lists.sourceforge.net |

1.1.5 also seems to work, but I would trust 1.1.6 more.
