Re: [FLASH-USERS] problem

Hello Malgorzata,

There are several things that might contribute to that
message.

First, I think that what the message is telling you is that you
need to set the environment variable "XFLASH_DIR" so that IDL will
know where to look for the routines. The routines are in the directory
tools/fidlr2 in the Flash source distribution.

For tcsh, this line works for me on one of our machines:

setenv XFLASH_DIR /scratch2/calder/FLASH2.3/tools/fidlr2

You could put the equivalent line in your .cshrc if
you are using that shell so that the environment variable would
be set every time you start a shell.

Then if you haven't done it, you add the same path to the
enviroment variable "IDL_PATH". Here's what mine looks like:

setenv IDL_PATH
/scratch2/calder/FLASH2.3/tools/fidlr2:/opt/pkgs/idl5.6/idl_5.6:/opt/pkgs/idl5.6/idl_5.6/lib

That adds the fidlr2 directory to the IDL path. Again, you could
put this in a .cshrc file.

Finally, be sure that you have compiled the shared executable using
either Makefile.linux or Makefile.sgi for linux or SGI machines, or
your own version for the system you are using. You most likely will need
to edit the makefiles to add the correct path in any case. Compiling
should produce a file named "h5_wrappers.so".

Hope this helps,

Alan
