I am trying, without success, to build a FreeBSD kernel with Linux compatibility. I have installed the package linux_lib-1.0 which seems to come with only the following brief instructions :- These libraries are part of the linux compatibility options for FreeBSD. To get linux compat working you will need 1) A linux binary such as doom, Wingz, or maple 2) a kernel with ``options LINUX_COMPAT'' in the config file 3) these libraries 4) the linux compat lkm (ie run /usr/bin/linux) then run the linux binary. I added the "LINUX_COMPAT" option to the config file, I also tried "COMPAT_LINUX" as other options which include "COMPAT" are of the format "COMPAT_xxxxx", but in both cases the Makefile produced contained no reference to "linux", except for the options line. I would expect the build to include some or all of the files in /usr/src/sys/i386/linux. Also, the instruction 4), " the linux compat lkm (ie run /usr/bin/linux)" is puzzling me. There is no file called "linux" in /usr/bin, or anywhere else on my system (there is an executable "linux_mod" but that just produces the error "Exec format error. Wrong Architecture" which all Linux programs seem to give. I am at a loss as to how to make it all work. Any help would be greatly appreciated. Regards, Mark Ovens (100104.10@compuserve.com)
