Current CVS doesn't build using ECW support with GCC 4.1

[luca.casagrande@…]

Hi to all!
I am trying to build current CVS, using GCC-4.1.1 and enabling ECW support for ECW-3.3

This is the configure summary:

Thanks for your help

I'm taking this bug after longer talk with Luca on the #gdal channel.

[Mateusz Łoskot]

Summary from chat with Luca:

1. Luca uses libecwj2-3.3 but installed form Gentoo packages
2. I use the same version but compiled and installed manually
3. We've revealed that there is problem with files from Gentoo. Comparison of header NCSJPCBuffer.h file (ECW SDK version 3.3) on Luca's and mine installation gives different results:

a) Luca's file: NCSJPCBuffer.h:178

CNCSJPCBuffer::CNCSJPCBuffer( const class CNCSJPCBuffer& src )

b) Mateusz's file NCSJPCBuffer.h:178

CNCSJPCBuffer( const class CNCSJPCBuffer& src );

So, it seems ECW 3.3 from Gentoo has some problems - old files.


I'm going to leave this report open and wait for new notes from Luca.

Additional note, GDAL (current CVS) builds on my Ubuntu 6.06 using GCC 4.0.3 and libecwj2-3.3-2006-09-06.zip with success.

After recent Luca's note, I close this bug as fixed, but in fact NOT A BUG in GDAL, but problem with Gentoo packages of ECW SDK.
