I think that the source of most problems is the link command used. On a=20
previous report there were many plplot API entries that were missing,=20
although the command line specifies -lplplot.

Perhaps Don's AIX isn't fully supported by libtool? Although libtool *say=
s*=20
during configure that it *knows* how to build shared libs in the detected=
=20
system!

   checking build system type... powerpc-ibm-aix4.3.3.0
   ...
   checking whether the linker (/bin/ld) supports shared libraries... yes
   ...
   checking if libtool supports shared libraries... yes
  =20
I'm afraid that without a AIX system it will be difficult for us to trace=
 and=20
fix the problem.

Yes,=20

1-Disable *everything*,=20
--disable-tcl --disable-tk --disable-itcl --disable-cxx --disable-f77 =20
--enable-dyndrivers --disable-static --enable-shared.
Only the C library will be build with shared libs and dynamic drivers. Do=
n't=20
forget to follow Alan's recomendations and unpack the sources fresh each =
time=20
-- or at least do a "make clean".

2-If the above don't work, the next step will be giving up of shared libs=
 and=20
build only static libs:
 --disable-tcl --disable-tk --disable-itcl --disable-cxx --disable-f77=20
--disable-shared

3-Don, you might need the fortran bindings, but if you can't compile the =
basic=20
C library there is no hope for you (for now, please be patient and wait f=
or=20
5.2.1)
