Hi, I am trying to compile IOAPI 3.2 with ifort, and it succeeds when “make” under /ioapi, and there is libioapi.a under /Linux5\_x86\_64ifort.
My loaded modules include:
intel/19.1.2.254 cray-hdf5/1.12.1.1 cray-netcdf/4.8.1.1
But when I tried to compile m3tool, it shows the attached air2m3 error message.
I also attach Makefile in m3tool.
Thanks your time.

Thanks for your time.
If I understand correctly, adding --disable-netcdf4 --disable-dap is in Makefile of NetCDF4 compilation. Is that right?
If so, I may not be able to solve it because NetCDF4 was not compiled on my personal computer but on the super computer (NERSC Cori). Should I connect with the helpdesk?
Also, I tried an alternative to compile with ftn, because in the previous Cori, ftn works.
Still, ioapi compilation succeeds, but m3tools compiling still has the attached error message.

Thanks for your reply, @cjcoats .
I tried the following 4 combinations for compiling ioapi/m3tools, but only ioapi succeeded. m3tools compilation still failed.
Under Linux5\_x86\_64ifort:
(1) -DIOAPI\_NCF4=1 in _Makeinclude.Linux5\_x86\_64ifort_
(2) activate -DIOAPI\_NCF4=1 in _Makefile_ without -DIOAPI\_NCF4=1 in _Makeinclude.Linux5\_x86\_64ifort_
Under Linux5\_x86\_64ftn:
(3) -DIOAPI\_NCF4=1 in _Makeinclude.Linux5\_x86\_64ftn_
(4) activate -DIOAPI\_NCF4=1 in _Makefile_ without -DIOAPI\_NCF4=1 in _Makeinclude.Linux5\_x86\_64ftn_
I attached the error message.

Run the net CDF commands _ncconfig_ and _nfconfig_ to find out what extra libraries you will need. Then contact your system administrator for where to find these libraries.
Or else build your own netCDF (as most people do), following the I/O API recommendations.
And note that you need to build netCDF with the **same compiler** you use for everything else: for example, an _ifort/icc_ netCDF won’t necessarily work with a _gfortran/gcc_ I/O API and vice versa…

Hi, @cjcoats
Some updates and one naive question.
The system administrator suggests exporting CRAYPE\_LINK\_TYPE and LIBRARY\_PATH before the m3tool compilation.
So I add the two command lines in m3tools/Makefile as follows:
export CRAYPE\_LINK\_TYPE=static
export LIBRARY\_PATH=$LIBRARY\_PATH:/global/common/cori/usg/curl/7.50.1/hsw/lib
I attach the message. It seems there is no error but I am not sure.

Can you give me a hint how to make sure I successfully compiled m3tools?
