[ncl-install] Status of NCL under MacOS 10.6 (64-bit)

[Mary Haley]

Guangshan,

Ted sent me a personal email and said that the HDF4 code was actually  
compiled under 10.5 and not 10.6, so he's not sure it will work under  
10.6.

I see that Sourish posted a response. The question I have about using  
gcc 4.2 is whether you get a 64-bit compile by default. I think this  
is the heart of the issue: HDF4 is not expecting the MacOS build to  
be on a 64-bit system, so it tries to treat the configuration as if  
it's a 32-bit one. This causes conflicting information during the  
"configure" phase.

I believe that you could do a build from source if you went into 32- 
bit mode, by forcing the "-m32" option. However this defeats the  
purpose of getting a 64-bit system.

If anybody else has successfully built HDF4 under MacOS 10.6 in 64- 
bit mode, we'd love to hear from you.
