[netcdfgroup] NetCDF 4.4.1 Compile Error on Centos 6.8.

Hello All:

I am getting the following compile error in the ./libdap2 directory when 
building NetCDF 4.4.1 with the opendap options enabled (the error disappears 
when I disable DAP on configure).

Making all in libdap2
make[2]: Entering directory `/usr/local/netcdf-4.4.1/libdap2'
/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..

Has anyone else encountered this?

I am building with libcurl 7.49.1 locally installed (it also happens without a 
local install and just using the centos rpmsâs libraries).

The pesky lines noted above are as followsâ

dceparselex.h:~11

/* Forward */
struct DCEparsestate;
typedef struct DCEparsestate DCEparsestate;



and

dceparselex.h:~49

/*! Specifies DCEparsestate. */
typedef struct DCEparsestate {
    DCEconstraint* constraint;
    char errorbuf[1024];
    int errorcode;
    DCElexstate* lexstate;
} DCEparsestate;

Cheers and Thanks Much
