I’ve built netcdf using  
ifort 17  
netcdf-c-4.4.0  
netcdf-fortran-4.4.3

for c: ./configure --disable-shared --enable-parallel-tests --disable-netcdf4 --disable-dap --prefix=$NCDIR  
for fortran: ./configure --prefix=$NCDIR

I soft linked all files under /storage/highspeed/apps/netcdf\_4.4.x\_ifc17/lib to /storage/highspeed/apps/ioapi-3.2\_ifc17/Linux2\_x86\_64ifort

[jhuang@ncaqc2017 bin] nc-config --libs -L/storage/highspeed/apps/netcdf\_4.4.x\_ifc17/lib -L/storage/highspeed/apps/hdf5-1.8.18\_ifc17/lib -lnetcdf -lm [jhuang@ncaqc2017 bin] nf-config --libs  
unknown option: --libs

I also changed `-lnetcdff -lnetcdf` to `-lnetcdf` in all IOAPI makefiles, I am not sure should I do this or change opposite way in netcdf makefiles.

I am using nocpl for ioapi make file with Linux2\_x86\_64ifort  
I searched the questions on the forum, and tried all suggestions I learnt, but still it returned some undefined reference errors related to netcdf

Detailed error messages can be found:

Any suggestion will be helpful,

Thank you

Please check the Makefile in the m3tools directory and change it from

```auto
LIBS = -L${OBJDIR} -lioapi -lnetcdf $(OMPLIBS) $(ARCHLIB) $(ARCHLIBS)

```

to

```auto
 LIBS = -L${OBJDIR} -lioapi -lnetcdff -lnetcdf $(OMPLIBS) $(ARCHLIB) $(ARCHLIBS)

```

sorry for that. But, the method doesn’t work! I have created another topic ([https://forum.cmascenter.org/t/installing-netcdf-classic-for-cmaq-isnt-working/941](https://forum.cmascenter.org/t/installing-netcdf-classic-for-cmaq-isnt-working/941))  
Thank you.
