*** There is another problem after that one was solved: "make" bombs after a
short while with

cd tmp; make default
make[1]: Entering directory `/root/plplot-octave/plplot/plplot-961023/tmp'
make[1]: *** No rule to make target `stupidtk.c', needed by `stupidtk.o'.  Stop.
make[1]: Leaving directory `/root/plplot-octave/plplot/plplot-961023/tmp'
make: *** [all] Error 2

I seem to have solved it with

/root/plplot-octave/plplot/plplot-961023 # cp bindings/tk/stupidtk.c tmp

from the plplot-961023 directory that the tar file unpacks into. However, this
is not the correct solution which is to mend the Makefile!

*** Having done that, there is yet another problem!

After "make cdemos", many C functions compile to .o and then

gcc -c -DDOUBLE    -O  x17c.c
x17c.c:33: poll.h: No such file or directory
make[1]: *** [x17c.o] Error 1
make[1]: Leaving directory `/root/plplot-octave/plplot/plplot-961023/tmp'
make: *** [cdemos] Error 2

I solved this one by editing examples/c/x17c.c to change

#include <poll.h>


#include <.usr/include/sys/poll.h>

since that's where my (S.u.S.E-5.1 Linux) system has it ...

*** And, having done that, there's still another problem:

The library gets into


but when you try to run the cdemos you get, for each demo:

./x01c: can't load library ''

etc. I haven't solved this one yet ... (tried running ldconfig)
