i use cross-compiling from win32 to (target)linux... and get this error; "Recompiling BaseUnix, checksum changed for System"

i am using this snapshot:

You are mixing units from different snapshots together. While I think that in theory this should work if they are compiled from similar svn revisions, this is not tested and unsupported.

You have to compile you own Linux-i386 units instead of copying them from a binary Linux snapshot inside your Windows directory.
