No, Example: two modules kld.c and kld1.1: kld: http://pastebin.com/m67799565 Makefile: http://pastebin.com/m5418e5a7 kld1: http://pastebin.com/d154e8474 Makefile: http://pastebin.com/m79723138 In kld is public int var_from_kld declared. To access this variable from kld1 you have to uncomment macro MODULE_DEPEND My system: % uname -v FreeBSD 7.0-RELEASE-p5 #0: Tue Oct 7 19:05:20 CEST 2008 Tell me please if I do something wrong!
