I'm trying to install libnet..
but at make is this error :
make[1]: *** [drivers/ipxsocks.o] Error 1
make[1]: Leaving directory `/home/strycnine/libnet/lib'
make: *** [lib] Error 2
the file ipxsocks.o is missing
but I have ipxsocks.c
Can I create ipxsocks.o?(or generate)

Odd, it should probably be there..did you have any problems during the configure part?

The file ipxsocks.o is not missing.

make is running gcc to compile ipxsocks.c (to produce ipxsocks.o), but ipxsocks.c is failing to compile.

Could you post the compilation error(s)?

The "make[1]: *** [drivers/ipxsocks.o] Error 1", etc. just states that an error occurred, not what the error was.

$make
make -C lib/ lib
make[1]: Entering directory `/home/strycnine/libnet/lib'

here is internet.o , it's the same thing

Find the part of the makefile which has the option -Werror.

Remove that option.

It's causing warnings to be interpreted as errors by the compiler.

Looking at libnet's Makefile (I just downloaded it myself to check), this might actually be in ports.mak
