Hello,  
I find the error when I was compiling MCIP, please help me to figure it out if you know it.

The makefile:  
FFLAGS = -O3 -I$(NETCDF\_DIR)/include -I$(IOAPI\_ROOT)/ioapi/fixed\_src  
LIBS = -L$(IOAPI\_ROOT)/Linux2\_x86\_64gfort -lioapi   
-L$(NETCDF\_DIR)/lib -lnetcdff -lnetcdf -lgomp

Thanks.

This may be a netCDF-4.7 bug. This looks like _libnetcdf.a_ has been configured using the flag  
`--disable-netcdf4`  
while _libnetcdff.a_ has not. “net.rumor” says that this is a bug in this particular version of netCDF.  
netCDF (both C and Fortran) is known to work correctly; perhaps you should try that.

Oops – the known-=to-work version – 4.4 – somehow got lost here.
