hdf4_read.py and hdf4_write.py tests failed on 64-bit Debian Lenny

[dron]

I have a lot of HDF4 tests failed on my 64-bit box using GDAL 1.6.0 RC3. I haven't much time to dig into this now, but I will return back ASAP. Meanwhile anyone interested is welcome to try to reproduce.

Andrey,

These tests pass fine for me on 64bit linux (ubuntu) but I use my own build of HDF4.2r1. I'd suggest starting investigations with the version and build of the hdf4 libraries. Perhaps build a local copy of hdf4 libs for comparison.

My experience is that a recent build of HDF4 lib is necessary on 64bit Linux. I've no problem with HDF4.2r4, but got crashes with earlier versions
