Hi,
I am trying to compile a package netcdf-3.6.2 on an ibm aix machine called IBM Regatta P690. The script i am using is:

#!/usr/bin/bash -f

export CC=xlc_r
export CXX=xlC_r
export F77=xlf_r
export FC=xlf90_r
export CFLAGS=-q64
export CXXFLAGS=-q64
export FFLAGS='-q64 -qextname'
export FCFLAGS='-qsuffix=f=f90 -qextname'
export FCFLAGS_f90=-qsuffix=f=f90
export CPPFLAGS='-DIBMR2Fortran -Df2cFortran -Dextname'
export ARFLAGS='-X32_64 -cru'
export NMFLAGS=-X32_64
export SED=/usr/bin/sed

./configure --prefix=/home/caos1/mecsmrao/netcdf_3.6.2 --enable-f90

gmake

hecking command to parse /usr/bin/nm -B output from xlc_r object... failed
