Greetings list users,

I got a problem compiling iptables for an embedded system (kernel 
2.4.19, ported gcc version 2.95.3 ). I use the folowing make command 
which stops in compiling extensions/libipt_TCPMSS.o

bash# make NO_SHARED_LIBS=1 KERNEL_DIR=/opt/embedded/kernel
Extensions found:
tricore-gcc -O2 -mtc13 -mall-errata -Wa,-mdmi12 -s -static  -Wall 
-Wunused -I/opt/embedded/kernel/include -Iinclude/ 
-DIPTABLES_VERSION=\"1.3.1\"  -DNO_SHARED_LIBS=1 
-DIPT_LIB_DIR=\"/usr/local/lib/iptables\" -c -o iptables.o iptables.c
...

make: *** [extensions/libipt_TCPMSS.o] Error 1

When I use
make NO_SHARED_LIBS=1
I can compile libipt_TCPMSS.o but get an error with the next:
extensions/libipt_TOS.o
cause it cannot find
linux/netfilter_ipv4/ipt_TOS.h
which does not exist in my kerneltree.

Anybody an idea. I'm clueless in the moment.

Regards Marcus
