The additional forge-pkgs (ex. Octave3.6.4_gcc4.6.2_pkgs_20130331.7z) contains the already compiled

==== signal ====
+
Normally windows users can't just install octave forge packages with
* findpeaks.m, print error if data is not a column vector (error: vertical dimensions mismatch (1x10000 vs 1x1)
+
  pkg install package
 +
or
 +
  pkg install -forge package

because their system lacks a build system with autotools, make, c++ compiler etc.

=== bisect bug 42612 ===
 
 
For bug #42612 I created a minimal script which fails: clf_fails_42612.m
 
subplot (2,1,1);
 
plot (1:5);
 
legend ('hello', 'location', 'northwestoutside');
 
clf
 
 
And the script which runs it, bisect_clf.sh:
 
#!/bin/bash
 
SRCDIR=~/src/octave-untouched-src
 
BUILDDIR=~/src/bisect_build
 
cd $BUILDDIR
 
## Try a simple build first
 
if  ! make -j 6
 
then
 
  # make failed, run bootstrap and configure
 
  cd $SRCDIR
 
  ./bootstrap || exit 127
 
  cd $BUILDDIR
 
  $SRCDIR/configure FFLAGS=-g CFLAGS=-g CXXFLAGS=-g --enable-bounds-check --disable-java --disable-gui --disable-docs|| exit 127
 
  make -j 7|| exit 127
 
fi
 
cd $SRCDIR
 
$BUILDDIR/run-octave -q clf_fails_42612.m
 
ret=$?
 
echo $(hg id) $ret >> clf_fails_42612.log
 
exit $ret
