Dear Graeme, group, I am having difficulty compiling the latest development sources (as of 2012-01-25). Lots of executable's are not build. The main problem seems to be the lack of "xvec.c" and "xvec.h" in xicc folder. Placing (possibly) older versions here, fixes most errors :) Still 5 executable's are not being build, mainly due to: "lack of <spectro>libdisp.lib". From the build log: ------ cl /nologo /c /Fospectro\mongoose.obj /DNT /MD /Od /Z7 /DARGYLLCMS /DNATIVE_USB /DENABLE_SERIAL /DENABLE_USB /Ih /Inumlib /Iicc /Icgats /Irspl /Ixicc /Igamut /Ispectro /Iplot /Iusb\driver /IC:\Program\Include /IFiles\Include /I(x86)\Microsoft\Include /IVisual\Include /IStudio\Include /I10.0\VC\\Include spectro\mongoose.c ...failed Cc_ spectro\mongoose.obj ... ...skipped <spectro>libdisp.lib for lack of <spectro>libdisp.lib(mongoose.obj)... ------ Please could you have a look? The last version which build well (on my system, that is), is the development version from 2012-11-26. My compiler is Visual C++ 2010, 32 bit. Thanks and greetings, Auke Nauta
