Hi Guangshan,

    I remember running into difficulties while compiling HDF4 on my Snow Leopard, but I eventually managed. I do not exactly remember how, but one of the problems I ran into was what you reported. Some versions of gcc (such as gcc-4.4.x) do not accept the "-arch" flag. Try removing that from your cflags, or try using gcc-4.2.x.

    I also had problems compiling HDF4 with Mac's compiler. I finally managed with gcc-4.4.1 installed by fink (without the "-arch" flag, of course).

Hi Ted,

I just tried to build HDF4 on 10.6 as the instruction. I am failed. Could you forward my email to your colleague? I would like to discuss with him.

I came to the "configure" step. But I could not use "CFLAGS="-Os -arch i386 -arch ppc -arch x86_64 -arch ppc64"

It gave me the following error:

checking whether make sets $(MAKE)... (cached) yes

checking for gcc... gcc

checking for C compiler default output file name... 

configure: error: C compiler cannot create executables

See `config.log' for more details.

I got rid of this option, it could be configured. I finished the left steps and type "make check".

It would pop out this error:

make[3]: *** No rule to make target `../../mfhdf/libsrc/libmfhdf.la', needed by `fortestF'.  Stop.

I cd to mfhdf/libsrc directory and typed "make" to make libmfhdf.la.

The building progress continued, but it stopped again at reading 24-bit JPEG compressed image.

Testing  -- 24BIT RASTER IMAGE INTERFACE (24bit) 

24-bit JPEG quality 80 image was incorrect

ret=-9, sizeof(jpeg_24bit_orig)=3174

24-bit JPEG quality 30 image was incorrect

ret=-5, sizeof(jpeg_24bit_orig)=3174

24-bit JPEG quality 75 image was incorrect

ret=-4, sizeof(jpeg_24bit_orig)=3174

Mary, et al:

A colleague found instructions for building HDF4 on OS 10.6 in 64-bit  
here:

http://www.kyngchaos.com/macosx:build:hdf

He followed the instructions exactly, and was able to compile a 64-bit  
HDF library just fine.

Best,

Hi folks,

I've been working offline with Guangshan Chen who attempted to build  

NCL V5.1.1 on a 64-bit Mac OS 10.6 (snow leopard) system.

Unfortunately, there was a problem building the HDF4 library, and  

the HDF folks do not have a fix yet.  Guangshan contacted them and  

they responded that they will be getting such a system soon and hope  

to get it working.

Until this happens, building NCL from source code will not be  

possible, because HDF4 is not an optional package.
