graphviz-2.39.20150325.0445 has the same problem.

If the update procedure opens graphviz.sln first with MSVS2010, save and close,
and then with visual studio express 2012, the project is correctly updated.

Please add this information to the

After correct update, the build fails.
It is missing zlib.h and expat.h.
However, zlib and expat are marked as an optional libraries in [^]

So if they are required in windows, this should be stated. If they are not, a suitable config.h should be added to the windows folder, or some instructions added to winbuild.html

I removed the relevant lines from config.h, confirming that zlib and expat are really optional.

sfio.h does not compile, giving 830 errors.
First one is error C2143 on line 109:
    typedef ssize_t(*Sfread_f)
    _ARG_((Sfio_t *, Void_t *, size_t, Sfdisc_t *));

Other users are also affected by this, see for example [^]

The compiler error is due to VS getting confused since ssize_t is not defined at that point.
There should be a
#include <stddef.h>
somewhere in the beginning of sfio.h

Correction to previous note:
stddef.h does not define ssize_t.

I removed the include and added
#if defined(_WIN64)
typedef signed __int64 ssize_t;
typedef signed int ssize_t;
#endif /* _WIN64 */

as per [^]

getopt is also a dependant library, but it is not mentioned in [^]

It should be added there, with a mention of whether it is an optional or required library.

libltdl is not in the sln, and no other visual studio solutions exist withing libltdl.
How is this library compiled?
Please add a solution as with the rest of the modules.

Unfortunately, you cannot build Graphviz on Windows by just unwrapping the source code and double-clicking on the .sln file. Setting up the build process for Visual Studio is, for historical reasons, more complicated than it should be. See the top of [^]
and the link there for more information. In particular, the build assumes you have installed the gtk+, Qt, ltdl, GTS and ANN libraries. These provide such sublibraries as zlib and expat. For Windows, Graphviz provides its own version of the getopt library. The ssize_t type is defined in ast_common.h. At some point, we do need to see what changes are needed for a 64-bit build.

In summary, and ignoring 64-bit builds, if everything is installed in the right places, one can just run fire off the .sln file and get a clean build.

Ah, I had thought these were optional libraries.
If you can comment that at the moment, the libraries are required for the windows builds, that´d be helpful, especially for us which only need a minimal graphviz library to embed.

There seems to be something funny going on in ast_common.h:
the definition of ssize_t is commented out.
This should probably be fixed somehow.

#define _typ_ssize_t 1 /* ssize_t is a type */

<removed some non-relevant lines here>

#if !_typ_ssize_t
# define _typ_ssize_t 1
typedef int ssize_t;

While getopt.h is provided by graphviz, the LIBRARY (or the C files providing
    extern int getopt(int, char *const *, const char *);
    extern char *optarg;
    extern int opterr, optind, optopt;
) is not included in graphviz-2.38.0

Various libraries are optional: one doesn't strictly need any of gtk+, Qt, ltdl, GTS and ANN. For the Windows build we distribute, we include all of them to provide the most features. Indeed, without gtk+ and GTS, many valuable features will be unavailable.

There are various Windows-specific configuration files stored in the windows subdirectory. These are copied into the root directory before the build. In particular, windows/ast_common.h has #define _typ_ssize_t 0.

The implementation of getopt is included as part of the Windows version of the ingraphs library, which is link in by all programs using getopt.

As I wrote above, everything is there and works properly if one follows the procedure outlined in build.bat and further detailed at [^]

Ah, sorry about that. My browser was displaying the previous version of winbuild.html, which did not mention the new procedure for Graphviz versions ≥ 2.30.

In any case, since you cannot mix libraries compiled with previous versions of VS [^]
and some of graphviz dependencies do not compile in VS2012, I will not be able to get a working version anyway.

Thanks for the support.
