[netCDF #RBY-219136]: netcdf-3.6.2-beta4 build problem

> Hi,

> I think netcdf 3.6.2-beta4 may disregard or over-ride user-specified

> 502  export CC='gcc'
> 503  export CXX='g++'
> 504  export CPPFLAGS='-DNDEBUG -DpgiFortran'
> 505  export CFLAGS='-O -fPIC -m64 -march=opteron -mmmx -msse -msse2
> -m3dnow -pipe -fexpensive-optimizations -mfpmath=sse,387'
> 506  export FC='g95'
> 507  export F90='g95'
> 508  export FFLAGS='-O -g -fno-second-underscore'
> 509  export F90FLAGS='-O -g -fno-second-underscore'
> 510  ./configure --prefix=/usr/local --disable-shared >

Howdy Charlie!

Hope you are having a nice New Year so far!

I am just about to release a beta5 which eschews all setting of flags. At 
least, that is the goal. However it is a challenge to do this and still not 
require the user to know what flags to set. However, I think I can manage it.

I'll send you email when the new beta5 release is ready...

Thanks!

Ed
