Re: [netcdfgroup] NetCDF 4.4.1 Compile Error on Centos 6.8.

Not sure what is going on; it seems to compile ok for me
using gcc version 4.9.3 (under cygwin).
It is possible that other version will not allow
specifying the same typedef multiple times.

In any case, I am attaching the modified dceparselex.h that you
should use (I think is the same as the changes I suggested).

Thanks Dennis.

That got me over one hump.

Alas there is a new hump though (also in the libdap2 directory):

Odd, something changed at some point.
In any case try changing line 50(?)
from
typedef struct DCEparsestate {
to
struct DCEparsestate {

and line 55(?)

};

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).

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 rpms’s libraries).



The pesky lines noted above are as follows…



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
