I need GDAL with both Shapefile and HDF4-Support, if possible in 64 bit.
Since the normal GDAL-versions from http://www.gisinternals.com/sdk/ have Shapefile, but no HDF4 and the version from FWTools
has HDF4, but no Shapefiles, Im afraid I have to compile a GDAL-version by myself.
The problem is that Im 'just' a geographer with programming skills, but no real IT-expert, and Ive never compiled open source by myself,
so maybe my question is quite simple for you.

First Ive downloaded the source code from http://trac.osgeo.or.../DownloadSource.
The I opened makegdal90.vcproj with Visual Studio 2010. It needed to do some updates, then it opened.
If I compile it without changes, I get a GDAL-folder with a new GDAL19.dll.
If I try to use this whole folder in my C#-project that works with normal GDAL-versions, I get a error.
But if I only copy the new GDAL19.dll over the old one in the existing GDAL(32 bit)-folder it works.
Is this how it should be or is something going wrong here already ?

The second step is to switch to 64bit, in nmake.opt I changed the following entry:
# Uncomment the following if you are building for 64-bit windows
# (x64). You'll need to have PATH, INCLUDE and LIB set up for 64-bit
# compiles.
WIN64=YES
Then I changed the setting of the VS-project to X64 and compiled again.
It still works as before: I get a new GDAL19.dll that works fine in my old GDAL(64 bit)-folder.

But then I cant do the third step, including HDF4. I found and changed the following section in nmake.opt:
# Uncomment the following and update to enable NCSA HDF Release 4 support.
HDF4_PLUGIN = NO
HDF4_DIR = C:\HDF
HDF4_LIB = /LIBPATH:$(HDF4_DIR)\lib Ws2_32.lib
I tried it maybe 100 times, but it never worked. Sometimes I get a corrupt GDAL19.dll, sometimes I get >100 errors when compiling
and sometimes I get a working GDAL19.dll without HDF4-support. I've read almost every Google-hit in English and German I found,
but it never worked. One problem is that the files mentioned there do not exist in the HDF-versions Ive downloaded. I guess, this
tips were for much older versions of GDAL and HDF4.

So can anybody give a step by step tutorial "How to compile GDAL with HDF4 for dummies" ?
I need to know which HDF4-files I need, where to get them, and what exactly I have to write in nmake.opt.
Or is there a ready to use GDAL-download with HDF4 and Shapefiles somewhere ?
(32 bit would be OK to, that isnt that important)

Isn't there an osgeo or gdal mailing list that could provide better response? I had some issue at one point, I remember, and I managed to find an IRC group, where I chatted with Frank Warmerdam and got it resolved (FW is mr GDAL)

Yes, find the GDAL IRC group on freenode. FrankW helped me through many issues I had with GDAL, and other developers are often in there to help as well.

Try installing GDAL/OGR with OSGeo4W, my installation has the HDF drivers (HDF4, HDFImage, HDF5, HDF5Image) with it on Windows 7. You can include (or add/remove later) optional features and drivers with the "Advanced Install" option.

I'm not sure about 64-bit versions, I have not built GDAL for a few years (a colleague did it including HDF4), but last time I looked you could not build for 64-bit using the free version of Visual Studio.

BTW, what makes you think that FWTools does not have the ESRI Shapefile driver? It always did for the builds I used.

What makes you think it's not there? You should see it near the top of the list with ogrinfo --formats.

[David_1980]

We've got the commercial version of VS 2010, it is able to compile GDAL (without HDF4) or other applications in 64 bit.

About FWTools:
I found out it should have Shapefiles from another tip yesterday, but for some reason, C# doesnt recognize any feature-type-drivers, trying to show the ogr-drivers throws an exception when using the FW-Tools-GDAL. With other GDAL-version the same code works fine, thats why I thought FWTools has only raster-drivers build in.

The error is:
The type-initialiser for "OSGeo.OGR.Ogs" has caused an exception.
System.EntryPointNotFoundException: The entry point "CSharp_OLCDeleteField_get" was not found in the DLL "ogr_wrap".
at OSGeo.OGR.OgrPINVOKE.OLCDeleteField_get()
at OSGeo.OGR.Ogr..cctor()
(translated from German by myself)

My code for that:
(..)
//Without Ogr.RegisterAll() it works fine:
Ogr.RegisterAll();
(..)
for (int i = 0; i < Ogr.GetDriverCount(); i++)
Console.WriteLine(Ogr.GetDriver(i).name);
(..)

As said, the same code works if Im using another version of GDAL, I already created a lot of shapefiles with it. (32 or 64 bit)

@frax:
To be honest, I asked in several forums, including the official mailing-list-web-interface.
At least I have found out that there is a tool for converting HDF4 to HDF5 and that FWTools should work with Shapefiles, so there are 2 new options. But Ive got no new hints about compiling GDAL+HDF until now.

PS.:
I already tried OSGeo4W some time ago, but as far as I remember it didnt work at all, maybe its worth another try..

FWTools is really out of date, so I doubt it's sensible to compare. I would check assumptions with the GDAL utilities first.

[David_1980]

Maybe I need another(older) version of the GDAL-C#-bindings to use the Shapefile-support from the FW-Tools-GDAL ?
As said, the raster-formats are already working, if I could use Shapefiles at the same time, it would be enough for now.
(Maybe we would need a newer version of GDAL later, but one step after the other..)

Has anbody of you used the FW-Tools-GDAL in a C#-project ?
