Re: [Lcms-user] Getting my feet wet with LittleCMS

[<Mar...@li...>]

Hello Roger,


The missing headers you report are probably libtiff and libjpeg.  
Unlike linux, there is no standard installation for those libraries in  
windows, so I assumed some directories: in particular C:\jpeg-8d and  
c:\tiff-4.0.2\libtiff
You may want to change those in configuration properties, VC++  
directories. But anyway those for tifficc and jpegicc and not strictly  
required for the core CMM.

The errors you get are because you are not linking the library with  
your project. Regarding lcms2.h, you only need to put #include  
"lcms2.h", you are not supposed to copy the whole file contents.

You could try a very simple program to experiment linking. In visual  
studio you can add a dependency and you got linking automatically.  
Take a look on any of the projects in the lcms2 solution, linkicc or  
transicc for example.

Please let me know if this worked for you.

Regards
Marti.
