Hi Pritpal,
Do we need to compile PRG/C application sources/third party libraries with exactly same switches with which Harbour is compiled? OR -DHB_MT_VM is enough?
It's only needed for some special cases dealing with HVM internals, like that file in xhb. For normal .prg files, it's never needed. For regular C interface code it should be never needed, but the .c (and also .prg) code should ideally be written to support MT mode too. It'd far from ideal to have two versions of xhb.lib, so if there is any chance to fix this, we should try to do it.
