Well, I can forward you complains to the plplot list :-) Might I? I've
done it!

PLplot is going to have a CVS, and I hope that this will give a warp in
development. After all PLplot is the only GPL multi-platform/language
graphics library, isn't it?

What is your OS? there is a pre-built plplot and plplot_octave debian
package, maintained by Rafael, which is also an Octave user.

I configure plplot with all but the xwin and tk driver; I would
recommend to even discard the tk driver for start. *my* configure
options are:

./configure --with-double --with-gcc --disable-dp --with-opt \
--with-shlib --disable-cxx --disable-f77 --disable-itcl \
--disable-linuxvga --disable-python --disable-mskermit

you might also try leaving out the --with-shlib, which often is platform

My tcl/tk is in /usr/local, and is founded. But sometimes the generated
makefile contains the incorrect version of the libraries,
libtcl7.6.a(so) instead of libtk8.0.a(so) etc.

What is your tcl/tk version? perhaps you should configure with
--disable-tk, for start.

My makefile (in plplot-990122/tmp) has the following references to

$(PLLIB_SO):    $(LIB_OBJS) stupidtk.o
    -$(RM) $(PLLIB_SO)
    @echo ""; echo "Building shared library"; echo ""
    cd shared; \
    $(SHLIB_BUILD) ../$(PLLIB_SO) \
        $(LIB_OBJS) stupidtk.o  
    ln -sf $(PLLIB_SO) $(SONAME)
    @echo ""

    $(CC) $(CC_FLAGS) stupidtk.c
    cd shared; $(CC) $(SHLIB_CCFLAGS) $(CC_FLAGS) ../stupidtk.c

stupidtk$O: stupidtk.c

Perhaps we should maintain any further conversation private? unless
someone says no.
