[Lcms-user] lcms-2.0 preview

[Guy K. K. <g....@ma...>]

To check it out I have created a little SConscript file to build lcms2 as a 
shared library (see the SConscript at end of mail). I don't know what other 
libraries are needed, but I just assumed for now the usual candidates that 
were also needed for versino 1.1.7 ['m', 'jpeg', 'tiff', 'z'].

Unfortunately there seems to be either something wrong with the code, or the 
code is pretty platform dependent and only works on M$ VisualWhatever 2008 (as 
I am implying from the included project files for that platform).

Any ideas?
