Ref - Packet Filter compilation problem

Hi ,

I have copied the sample code for PF from QNX site and try to compile in QNX x86 PC but it throws an error.

Please tell me how to compile and load.

make -j 1 -Cdll -fMakefile
make[1]: Entering directory `/home/senthil/pfil/x86/dll'
../../common.mk:10: /home/senthil/pfil/../lsm.mk: No such file or directory
make[1]: *** No rule to make target `/home/senthil/pfil/../lsm.mk'.  Stop.
make[1]: Leaving directory `/home/senthil/pfil/x86/dll'
make: *** [all] Error 2

Thanks
K.Senthil

Looks like you didn't copy enough.  Please see this page.
Picking out an isolated piece and trying to build it
isn't a supported configuration.

You need to include <net/pfil.h> and have _KERNEL defined.

The following works for, where /home/seanb/io-pkt
is where I have the networking repo checked out.

$ cc -shared  -I /home/seanb/io-pkt/sys -Wall -fno-builtin-log \
 -D_KERNEL -Wp,-include -Wp,/home/seanb/io-pkt/sys/qnx.h \
 -Wl,-Bsymbolic -o lsm-senthil.so s.c
