Hi I included the two files in my kernel module : #include <netgraph/netgraph.h>#include <netgraph/ng_message.h> And here is contents of Makefile: =C2=A0 KMOD=3D echo=C2=A0=C2=A0 SRCS=3D char_dev.c =C2=A0 .include <bsd.kmod.mk> When I try to run make I face the following errors: @/netgraph/ng_message.h:59: error: expected specifier-qualifier-list before= 'u_char' @/netgraph/ng_message.h:227: error: expected specifier-qualifier-list befor= e 'uint32_t' @/netgraph/ng_message.h:269: error: expected specifier-qualifier-list befor= e 'u_int32_t' @/netgraph/ng_message.h:283: error: expected specifier-qualifier-list befor= e 'u_int32_t' @/netgraph/ng_message.h:294: error: expected specifier-qualifier-list befor= e 'u_int32_t' @/netgraph/ng_message.h:306: error: expected specifier-qualifier-list befor= e 'u_int64_t' @/netgraph/ng_message.h:332: error: expected specifier-qualifier-list befor= e 'u_int' @/netgraph/ng_message.h:352: error: expected specifier-qualifier-list befor= e 'uint32_t' In file included from @/sys/lock.h:36, =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0from @/netgra= ph/netgraph.h:52, =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0from char_dev= .c:2: @/sys/_lock.h:36: error: expected specifier-qualifier-list before 'u_int' In file included from @/netgraph/netgraph.h:52, =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0from char_dev= .c:2: @/sys/lock.h:60: error: expected specifier-qualifier-list before 'u_int' In file included from char_dev.c:2: @/netgraph/netgraph.h:1187: error: field 'tag' has incomplete type *** [char_dev.o] Error code 1 Stop in /extra/char-dev.

My suggestion is to start with that and add in your code a bit at a time To see it compile, go to /usr/src/sys/modules/netgraph/sample and type "make to make your own module, copy the build directory to /usr/src/sys/modules/netgraph/mymodule copy the source files to /usr/src/sys/netgraph/ng_mymodule.h /usr/src/sys/netgraph/ng_mymodule.c and replace all instances of 'sample' in all the files and the Makefile with 'mymodule' Then go to /usr/src/sys/modules/netgraph/mymodule and make sure it still compiles then add all your own code, adding include files as you need them recompile it every time you have the oportunity while you are working on it. > > And here is contents of Makefile: > > KMOD= echo SRCS= char_dev.c > > .include <bsd.kmod.mk> > > When I try to run make I face the following errors: > > > @/netgraph/ng_message.h:59: error: expected specifier-qualifier-list before 'u_char' > @/netgraph/ng_message.h:227: error: expected specifier-qualifier-list before 'uint32_t' > @/netgraph/ng_message.h:269: error: expected specifier-qualifier-list before 'u_int32_t' > @/netgraph/ng_message.h:283: error: expected specifier-qualifier-list before 'u_int32_t' > @/netgraph/ng_message.h:294: error: expected specifier-qualifier-list before 'u_int32_t' > @/netgraph/ng_message.h:306: error: expected specifier-qualifier-list before 'u_int64_t' > @/netgraph/ng_message.h:332: error: expected specifier-qualifier-list before 'u_int' > @/netgraph/ng_message.h:352: error: expected specifier-qualifier-list before 'uint32_t' > In file included from @/sys/lock.h:36, > from @/netgraph/netgraph.h:52, > from char_dev.c:2: > @/sys/_lock.h:36: error: expected specifier-qualifier-list before 'u_int' > In file included from @/netgraph/netgraph.h:52, > from char_dev.c:2: > @/sys/lock.h:60: error: expected specifier-qualifier-list before 'u_int' > In file included from char_dev.c:2: > @/netgraph/netgraph.h:1187: error: field 'tag' has incomplete type > *** [char_dev.o] Error code 1 > > > Stop in /extra/char-dev. > > > What's the problem?? > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org" > >
