[Gdal-dev] missing/wrong compiler option in nmake.opt

[Oscar ter Hofstede]

Hi,

I am trying to build a debug version of my application with the latest 
version of GDAL (1.2.6), including MrSid and ECW support.

I need to build with the debug run-time libraries (by specifying the option 
/MDd), since some other libraries I use are using debug functions that are 
only defined there (CrtDbgReport). However, if I build both my application 
and GDAL with the /MDd option, the application crashes in GDALClose() when 
closing a MrSid or ECW dataset.

Has this something to do with the MrSid and ECW libraries not being compiled 
with /MDd? I downloaded the latest versions of their libraries from their 
websites last week. Is there a solution to this problem?

Cheers,

Oscar.
