[FLASH-BUGS] Re: [HACKERS] Trouble with postprocessing files (fwd)

[JB Gallagher]

Vijay,

Vijay, it seems something is weird with h5_wrappers.so, in your original 
message I could see that the idl is running in 64-bit mode, so you would 
need a 64-bit h5_wrappers.so , I think on AIX that cc without arguments 
will default to 64-bit I think, however the -q32 and -q64 will force 
this. If you are stuck with the 32-bit hdf5 I suggest the following, 
edit the h5_wrappers.so Makefile and put "-q32" after the cc directive. 
Then see how idl is invoked on your system, it will be either aliased or 
linked under /usr/local/bin, if linked under /usr/local/bin just type 
"idl -32" , if aliased, then type "unalias idl" and then 'alias idl 
"/path-to-idl-installation/bin/idl -32" ' , the main thing is that the 
h5_wrapper.so and idl need to be running in the same bit mode they both 
have to be either 32 or 64-bit, if the hdf5 you link to to make 
h5_wrappers.so in 32-bit this will definitely cause a problem, and I 
would thnk it wouldn't even build. Anyway try what I suggest above and 
let us know what happens.
