[Gdal-dev] GDAL with ECW SDK 3.3 on Mac OS X

[Armin Burger]

Hello

I guess that some folks succeeded in compiling GDAL with ECW support 
under Max OS X (Tiger).  I tried the combination GDAL 1.3.1 and ECW SDK 
3.3 RC1. After applying the once on this list mentioned small patch for 
the SDK it compiled fine.

Then GDAL gives an error during the configure script:

...
checking for libNCSEcw.so or libecwj2... configure: error: not found in 
/usr/local/lib or /usr/local/bin.


The libraries of ECW are under /usr/local/lib. I checked the configure 
script and just tried a link

  /usr/local/libecwj2.dylib -> /usr/local/lib/libNCSEcw.0.0.0.dylib

The configure then went on. Also the compilation went quite far. But 
somewhere towards the end of the make I get the error

...

Does anybody have a clue what this could mean?

I set the LD_LIBRARY_PATH and LD_INCLUDE_PATH to all directories where I 
think it was needed.

Thanks for any help,

Armin
