Re: 20051101: netCDF Perl Interface - problem using netcdf-perl: __buitin__alloca

John,

Because the perl(1) utility was built using gcc(1), you'll have to use
that compiler to build the netCDF and NetCDF-Perl packages in order to
get them to link together.

I'm sorry, but that's just the way it is.

Regards,
Steve Emmerson

Hi Steve, thanks for your prompt reply.

Perl was made with gcc.  Tried building perl 5.8.7 with pgcc, here's
the tail of the 'make' output:

make[1]: Entering directory `/home/nordlie/download/perl-5.8.7'
cp ext/re/re.pm ext/re/re.tmp && sh mv-if-diff ext/re/re.tmp lib/re.pm

./miniperl minimod.pl > minimod.tmp

cd lib/unicore &&  ../../miniperl -I../../lib mktables -w

Nope, built that with PGI:

        Built and installed
        NetCDF 3.5.1, using following environment variables:

        setenv CPP_NETCDF -I/usr/local/include
        setenv LD_NETCDF "-L/usr/local/lib -lnetcdf"
        setenv PERL /usr/bin/perl
        setenv PERL_MANDIR /usr/local/man
        setenv CC pgcc
        setenv CFLAGS "-O -Msignextend -V -fPIC"
        setenv FC pgf90
        setenv F90 pgf90
        setenv FFLAGS "-g -w -V"
        setenv CXX pgCC
        setenv CPPFLAGS "-DNDEBUG -DpgiFortran"

        as per PGI webpage:
        http://www.pgroup.com/resources/netcdf/netcdf351_pgi5x_64.htm

I double-checked the macros.make file after running configure to be sure
it was using the PGI compilers for C and FORTRAN, it was.
