[Gdal-dev] Compiling ECW JPEG 2000 SDK 3.2 beta

[Tom Lynch]

That's a peculiar situation - the makefile for libNCSEcwC (see 'makefile' in 
$INSTALL/Source/C/NCSEcw/NCSEcwC_SDK/) explicitly requires linkage to 
libNCSEcw, libNCScnet and libNCSUtil, so you shouldn't be able to build it 
without those libraries present on your system.

What are the contents of <install directory>/bin/<platform> after you run 
the build script?

Also, what edits have you made to NCSNightlyBuildUnix.ksh? It is usually 
necessary to edit the shebang line and the value of $NCSTOP - the shebang 
line should point to your shell of choice, and $NCSTOP should be the dir in 
which you unzipped the SDK archive.

Maybe the files are being created somewhere you don't expect them to be.

Tom.
