[gdal-dev] Re: dev-version of HDF4

[Knut-Frode]

The paths are taken care of by configure, and they are checked to be ok. 
I also tried with standard installation folders (/usr/lib/ /usr/include/ 
etc) but no difference. I did not compile, since configure fails.
So I believe it must be some incompatibility with the GDAL configure 
script and the standard HDF4-libraries I have used. The "lib not found" 
message from GDAL configure seems to be misleading.

Best regards from Knut-Frode
