[Gdal-dev] hdf4, hdf-eos and gcc 3.4 issues

[Vincent Schut]

My previous messages about this probably disappeared somewhere between 
servers, that's why resending...

GDAL-cvs doesn't build for me since a couple of days, and I think the 
combination of using hdf-eos and my compiler: gcc3.4, could be the cause.

So far I found out:

- the include of HdfEosDef.h from hdf4dataset.cpp doesn't work, because gcc 
can't find it. After changing the compile line to include '-I./hdf-eos', this 
was solved. I however don't know the appropriate place to add this 
(GNUmakefile?).

- gcc complains about not finding includes if they are between <> when they 
should be between "". This is the case for <ease.h> from HdfEosDef.h, and for 
<HDFEOSVersion.h> from EHapi.c.

- after these changes, I get the following error which is beyond my knowledge:

vincent at timo hdf-eos $ make

I think the lines from HDFEOSVersion.h generate the real errors, the other 
ones seem just warnings.
As I said, I'm stuck here.
