I am building a custom kernel based on = FreeBSD 6.0 kernel (I have to use this version cause I need to run an = application which is only available for FreeBSD 6.0). I conform to the = handbook to add the following lines in kernel configuration file to = enable DTrace support: options KDTRACE_FRAME options KDTRACE_HOOKS options DDB_CTF makeoptions WITH_CTF=3D1 Then I use the following commands to recompile my kernel and install = this new kernel: make buildkernel KERNCONF=3DKERNELNAME make installkernel KERNCONF=3DKERNELNAME The compiling process encounters an error: Unknown option "DDB_CTF", I = have no idea how to fix this? Could anyone help me to see why this happens?? Thanks in advance. Best, W. Wang
