Oyvind,

I tried adding those defines on ecw/makefile.vc and it did worked but I don't know if that is the right thing do to:

-        /DLIBECWJ2 /DWIN32 /D_WINDLL -DFRMT_ecw -DNO_X86_MMI
+        /DLIBECWJ2 /DWIN32 /D_WINDLL -DFRMT_ecw -DNO_X86_MMI -DECWSDK_VERSION=41 -DNO_COMPRESS

And, of course, I changed the setting on nmake.opt:

-#ECW_PLUGIN = NO
-#ECWDIR  =     C:\warmerda\libecwj2-3.3
-#ECWLIB  =     $(ECWDIR)\Source\NCSBuildQmake\Debug\libecwj2.lib
+ECW_PLUGIN = YES
+ECWDIR  =     "C:\Program Files\ERDAS\ERDAS ECW JPEG2000 Read SDK"
+ECWLIB  =     $(ECWDIR)\lib\vc90\win32\NCScnet4.lib \
+            $(ECWDIR)\lib\vc90\win32\NCSEcw4_RO.lib \
+            $(ECWDIR)\lib\vc90\win32\NCSUtil4.lib

That worked on 1.8dev and 1.7.3 as well but I guess we would need an expert opnion on that.
