I did as that but came across some problems,these are the jobs and the errors: 1) I copyed the files to the sys/dev/mydevice and added "dev/mydevice/mydevice.c optinonal mydevice" in the file /usr/src/sys/conf/files.i386,and added a line "device mydevice" in the sys/i386/conf/MYKERNEL(a copy of GENERIC),but met a error when config MYKERNEL:syntax error (the line I just added). 2) Then,I modified line in files.i386 as "dev/mydevice/mydevice.c standard",configed successfully,but another error occured when make depend(make buildkernel KERNCONF=MYKERNEL the same): ... ../../../dev/mydevice/mydevice.c:27:20: mydevice.h: No such file or directory ../../../dev/mydevice/mydevice.c:28:44: mydevicekern.h: No such file or directory ../../../dev/mydevice/mydevice.c:29:49: mydeviceioctl.h: No such file or directory mkdep: compile failed *** Error code 1 ... and the source code of mydevice.c is as follows: ... #include "sjy22b.h" #include "sjy22bkern.h" #include "sjy22bioctl.h" ... the three headers are just in the sys/dev/mydevice directory,I don't know why this happened. Need your suggestion! Thanks Yong -- ___________________________________________________ Play 100s of games for FREE! http://games.mail.com/help
