Re: ISIS initialization error

John,

I actually don't have HEADAS at all so I'm not too sure why I had that at all in my ./configure.

I have cfitsio2 installed, pgplot compiled and installed in /usr/local/pgplot and libslang2 installed.

I had previously resolved this same error by pointing to the inc and lib folders for the compiled version of pgplot.  In the first message for this thread the path is seen as being different:

---------------
Error linking to /usr/local/isis/lib/modules/pgplot-module.so: /usr/lib/libpgplot.so.5: undefined symbol: png_set_text

vs

Error linking to /usr/local/isis/lib/modules/pgplot-module.so: /usr/local/isis/lib/modules/pgplot-module.so: undefined symbol: cpggray
---------------

Also, replacing the pgplot-module.c just advanced to cpgconf missing symbol.

I think my problem now is just that I need to get isis to use libpgplot.so.5 as it had during the first email I had emailed.  I have used the following configure command with no success (although it has previously worked)

./configure --with-pgplotinc=/usr/include --with-pgplotlib=/usr/lib

Thanks,
Keith

pgplot-module.so is part of the isis distribution.

For some reason, it looks like your pgplot library doesn't have
the 'cpggray' subroutine.  That's why you're seeing the message
"undefined symbol: cpggray".

It's strange that this symbol is missing.

I recommend using the cfitsio and pgplot libraries included in
the HEADAS distribution.  To do that, configure isis like so:

  ./configure --with-slang=DIR --with-headas=$HEADAS

Is cpggray missing from the HEADAS version of pgplot?

In case that's the problem, I removed the reference to cpggray
from pgplot-module.c.  That modified version of the module
available in:
  ftp://space.mit.edu/pub/houck/tmp/pgplot-module.c
and can be used to replace:
   isis-$version/modules/pgplot/src/pgplot-module.c

To build a new version of the pgplot module after replacing
that file, do:

  cd isis-$version/modules/pgplot/src
  make clean all install

I hope there are no more missing symbols.

Thanks,
-John
