Guangshan,<div><br></div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>If anybody else has successfully built HDF4 under MacOS 10.6 in 64-bit mode, we'd love to hear from you.</div><div><br></div><div>--Mary</div><div><br><div><div>On Nov 11, 2009, at 4:27 PM, guangshan chen wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Hi Ted,<div><br></div><div>I just tried to build HDF4 on 10.6 as the instruction.
