Have you tried included the header file for the SD interface? That is mfhdf.h.
When you use the SD interface, you'll need mfhdf.h, which includes hdf.h. For
all the other interfaces, you'll only need to include hdf.h.

Subject: [Hdf-forum] Problem with include files when compiling HDF4 program
I'm trying to compile a program that uses the HDF4 libraries. I installed HDF4
on my computer in /usr/local/ and I have confirmed that all of the necessary
scripts, include files and libraries have been installed and that all
environment variables are set correctly. I created a Makefile that compiles my
two C files into object files and then links them together. When I compile the
first C file, "readHDFfuncs.c", the compiler tells me that all of the HDF4
functions being called have not been declared. This should not be happening
because my h4cc compiler is correctly including the proper directory.
I set the h4cc commands to -echo and have traced the compilation execution.
Everything seems to be correct, however for some reason the function
declarations are not getting through.
I have created a github to show you the
Included is the output of my make command (which, remember, includes the -echo
option for h4cc), the Makefile itself, my two C files, a header file, and the
contents of my include directory. I really hate dropping all of this on people
and asking for a solution but I have spent a lot of time trying to figure this
out and I would greatly appreciate it if someone could point out anything they
