Hi Orion:
The current status of this effort is I am done with all the relevant
epa_build configuration, but the result segfaults at run time.
Here is what I have done so far.
1. Implemented an epa_build of lapack and blas. ctest of that build
passed 100 per cent of all the many tests.
2. Upgraded the epa_build of swig-2.0.11 to swig-3.0.6 with your patch applied.
The result works well with PLplot for the non-octave case. For
example, the swig-generated Python, Lua, and Java bindings all work
well.
3. Implemented an epa_build of octave_lite which is octave-4.0.0 with
all optional components disabled. This version passes the simple test
octave:1> x=-pi:0.1:pi;
octave:2> plot(x,sin(x))
octave:3> exit
with the plot done with the default gnuplot. However, valgrind of
that simple test loses control of octave_lite (see below).
4. epa_built plplot_lite against this octave-lite version with no issues.
5. However, when I try the above simple test in a directory which
contains the following file (to enable the PLplot version of plotting)
wine@raven> cat .octaverc
warning("off","Octave:shadowed-function");
addpath("/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/build_plplot_lite/bindings/octave/PLplot","/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/build_plplot_lite/bindings/octave/PLplot/support","/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/build_plplot_lite/bindings/octave/misc","/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/build_plplot_lite/examples/octave","/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/comprehensive_test_disposeable/shared/build_tree/bindings/octave","/home/wine/newstart/build_script/build_dir-linux/epa_build/Source/comprehensive_test_disposeable/shared/build_tree/bindings/octave/PLplot");
global pl_automatic_replot
pl_automatic_replot=1;
where the form of this file has been suggested by bindings/octave/USAGE
the above simple plot test segfaults (where normally with PLplot built
against octave-3.x.y, this simple test generates a plot using the xwin device).
I would like to do further debugging of this segfault with valgrind,
but somehow valgrind is losing control of octave_lite so never
generates any messages after the normal burst of initial messages and
the commands go the same speed as usual (not the slow speed you
normally get with valgrind) regardless of whether I use gnuplot
(without segfault) or the .octaverc trick above to attempt to use
plplot (with segfault).
Tomorrow I will play with the configuration of the epa_build of
octave_lite to see if I can figure out a way to beat this valgrind
issue.
