[netCDF #WEP-155858]: NetCDF 4.2 Fortran on Ubuntu 12.10 (Intended to be used with ROMS ocean model)

Hi Alexis,

The error message you are getting

  /usr/bin/ld: ../f90/.libs/libnetcdff90.a(netcdf.o): relocation R_X86_64_32 
against `.rodata.str1.8' can not be used when making a shared object; recompile 
with -fPIC

indicates that you need to add "-fPIC" the the compiler options for gfortran 
when configuring
the netCDF Fortran library.  It may also be necessary to add -fPIC to the gcc 
options when 
configuring the netCDF C library.

Sometimes -fPIC is needed for 64-bit shared libraries but not for 32-bit shared 
libraries.  I
thought libtool was supposed to figure this out and provide the Position 
Independent Code
option automatically when needed, but it doesn't seem always do that when 
needed.

Please try configuring and building the netCDF C library with CFLAGS="-fPIC" 
and then 
installing it again.  Then try configuring and building the netCDF Fortran 
library
with FCFLAGS="-fPIC".  If "make check" doesn't work after that, please let us 
know.
We don't have an Ubuntu platform configured on which to test the netCDF Fortran 
build,
so we'd also like to know if this succeeds, in which case we'll add to the 
instructions.

Thanks for reporting the problem!
